MH370 missing

Malaysia Airlines MH370 from Kuala Lumpur to Beijing is missing.
Flight MH370, operated on the B777-200 aircraft, departed Kuala Lumpur at 12.41am on 8 March 2014. MH370 was expected to land in Beijing at 6.30am the same day. The flight was carrying a total number of 227 passengers (including 2 infants), 12 crew members.
Rumors that the plane has landed in Nanning, China are debunked. Chinese media had originally reported Vietnamese officials saying they've picked up a signal, but this has also been refuted. There has been no contact nor distress signals, and the case is especially puzzling as the plane lost contact at the safest moment of the flight. posted by divabat (1934 comments total) 123 users marked this as a favorite

A modern plane just disappearing like that is terrifying. My thoughts are with all those poor people on board and their families.

"There has been no contact nor distress signals" makes me think of TWA flight 800. Other than total catastrophic in-air destruction, it's hard to imagine another event in a modern airliner that wouldn't allow at least some sort of communication from the crew.

People on Twitter are speculating terrorism - who has such a beef against Malaysia that they'd attack Malaysia Airlines?!

This has gotten me really spooked. I am a lifelong flyer who's spent a lot of time on Malaysia Airlines. My parents just flew to Korea yesterday, possibly on MAS. This is hitting so many personal buttons, just wtf.

From The Guardian:

James Fallows, following the story in The Atlantic, says whatever has happened to the plane is unlikely to be a result of chronic poor practices by Malaysia Airlines (“a good, competent and modern airline”). The Boeing 777 also has an excellent safety record.


So if it crashed, I'm wondering if it was due to human error, which is why the Air France flight went down a few years back.

divabat: "People on Twitter are speculating terrorism ..."

It seems like with modern security measures that terrorism would be one of the least likely reasons. A more recent crash with no distress signal was Helios 522, which was a bizarre one.

:S

My aunt works in Beijing and frequently flies back and forth between Beijing and KL to visit our family there. She's probably flown that route a dozen times in the last couple of years. Hell, I've flown that route.

This is hitting way closer to home than I'd like.

I hope against hope that it turns up safe but it's looking like it's crashed. I've flown MAS a few times and always found them competent and safe.

Thanks for the post. I'm Malaysian, and this hits altogether too close to home too - I've been tracking flights to Beijing from Singapore this summer, and I really really wanted to fly MAS for sentimental reasons. I still want to, but this is just awfully sad.

Meanwhile, some erstwhile acquaintances of mine are speculating that it's a ploy or hoax to divert attention from the Anwar case, which is the most WTF thing ever.

It's WAY too early to jump to that conclusion, but in light of recent events, I'd expect Chinese officials to (pretend to?) do just that.

Here's the (first) MH370 thread on airliners.net, which is where I turn to for air-disaster information. It's morbid but they really know their stuff. From there I've learned:

* Route was KUL to PEK
* Unconfirmed but they suspect the specific aircraft is tail number 9M-MRO. That plane is only 11 years old.
* From records, 9M-MRO was involved in an accident in 2012. "The wing hit the tail of a China Eastern A340 with the tip left hanging. Not serious but noteworthy."
* This would be only the 4th ever loss of a 777
* Event now has a Wikipedia entry

My dad was a frequent flyer, including in that part of the world, and for all that he's been gone for 25 years, I still get a chill when I hear about an air crash. A plane just vanishing is even more frightening. It feels like we ought to be able to keep better track, and yet, just losing things and people is the norm through most of history, and knowing where everything is all the time is the anomaly.

Thank goodness the fact that this is such big news is because it is such rare news; considering the number of planes in the air at any one time it is a feat of engineering and human ability that there are so few catastrophic failures.

It's not terrifying that a plane could be lost, it's stupid. Planes should have satellite uplinks reporting GPS position. Consumer versions of that cost about $200. But commercial planes mostly don't have them. Stupid.

Also stupid is the breathless breaking news and up to the minute speculation and rumor. The 24 hour news cycle and instant worldwide Internet communication makes it worse. It's ghoulish, unhealthy infotainment.

At the risk sounding like a one-upsman, I flew from Boston-Logan to LAX a week before 9/11, and never thought more than "hmmm, that's weird."

Is that the flight where one of the pilots was pulling back on the stick while the other pushed forward, thus locking the controls until the plane lost so much airspeed it stalled despite there being absolutely nothing whatsoever wrong with the plane? That one was chilling to read about.

Nelson is right; there isn't an excuse for every single commercial flight to be outfitted with a GPS uplink. Planes should never be "lost" in this day and age.

Well, to be fair that was also written by someone who has family in KL, and - at least for me, having grown up here - is likely to be connected to someone on that flight, as I am rather distantly. For some people that's close enough that it gives them chills and saddens them, for some it isn't. And while it's not particularly commendable, it's natural that the first thought for many is "well, there but for the grace of God (or luck)", while others see the flip side of that and see that well, it just wasn't you.

But as the speculation turns into concrete fact, what happens will be less abstracted, and "perspective" will probably be more grounded to begin with, so we'll deal more with facts than "that is so scary to me because [X]".

Dad's just apologised to me for the misinformation. Can't blame them really, my parents are worrywarts enough without a catastrophe.

They are flying MAS. I told them to anticipate being stuck in Korea for a while - been hearing flights cancelled today. (I doubt they'd cancel all international flights, but given that this is so new for MAS who knows what the response is.)

I've been working with a youth arts project where local youth collaborate with Malaysian youth on issues of citizenship and identity. A bunch of our kids are flying to KL and vice versa. I'm going to break the news to them in our next class. Hoping no one we know has been lost.

Much respect for the airline posting this:

"We regret to announce that Subang Traffic Control lost contact with flight MH370 at 2:40 am today.

We are currently working with international authorities on the search and rescue mission and as at 1400 hours, 08 March 2014, we have no information on the location of the airline."

Sadly, I cannot imagine a United States airline making such a clear statement.

Regarding perspective, my father was an airline pilot. When I was a little kid, I couldn't mentally separate the plane my father was flying from any other plane. When he was on a trip and there was a plane accident, I thought he'd died until he came home. When he was home, I always asked him how he was going to be able to go to work now that his plane had crashed.

Anyhow, obviously I'm older now and have figured a thing or two out about the total number of planes. Also, my dad retired years ago. To this day, when I hear about a plane accident, I experience a reduced version of the same anxiety I felt forty years ago. It's irrational, but there it is. I don't know that I've mentioned this outside of my therapist's office before.

Anyhow, we all react the way we react to news of tragedy. I feel for the families and friends of everyone effected by this tragedy. Part of the reason I feel for them is because of my own personal anxiety - and obviously part is empathy and basic decency.

My sincere condolences to the families and friends. This is dreadful.

How is this supposed to prevent airplanes from disappearing? The aircraft in this case was equipped with a location-tracking system that was broadcasting and then stopped broadcasting. That's why it's missing.

Of note, a Chinese plane with 200 people on board passed through the trajectory of a North Korean missile seven minutes after a test earlier this week. The plane was flying from Shenyang in China to Tokyo.

To be clear, I am not suggesting that North Korea was involved in this. Given the location, that seems highly unlikely. But given how recent that incident was, it felt worth flagging for the thread.

My condolences go out to the families of the passengers and crew.

the plane lost contact at the safest moment of the flight.

This is an absurd phrasing from CNN. Cruise is a safer phase of flight than landing or takeoff, but that doesn't make it "the safest moment".

It's not terrifying that a plane could be lost, it's stupid. Planes should have satellite uplinks reporting GPS position. Consumer versions of that cost about $200. But commercial planes mostly don't have them. Stupid.

The term "lost" is used when there is no conclusive knowledge of the state of the aircraft. It's a more complex situation than just "if only we had GPS tracking". The better phrasing would be that controllers have "lost contact with" the airplane, which is also mostly a statement of uncertainty but it at least avoids the implication that position is the operative issue. Perhaps some of your displeasure at news outlets for reporting speculation and rumor should temper your rash claims of airline and FAA stupidity.

Based on that Guardian feed, there's a lot of anger from the families of passengers due to lack of information. I guess that's understandable, but at the moment there really seems to be no information.

For some reason I'm following this closely, I guess because of several trips I've made to Malaysia over the years, and because of the way the airline has just disappeared without any indication of where or what went wrong.

I'm not one for praying, personally, but I'm sure hoping.

I think the problem with the wording there is that it implied that the safest moment is more like a singular peak (during which the plane disappeared), whereas the reality is that all the moments during cruise (which account for the longest portion of flight) are safer than the takeoff and landing phases.

amro: cellphones don't work too well when you're a hundred miles from land over the open ocean.

Justinian: "planes should never be lost in this day and age" — per the Aviation Herald incident log, the plane was on radar when it was observed to make a sharp turn and rapid descent, without any communication. Contact was then lost, presumably when the aircraft disintegrated in mid-air or crashed. The trouble is, it will have been cruising at approximately 550mph, at an altitude of nearly seven miles, when it went down. The wreckage could easily be scattered over an area of the South China Sea twenty miles long and five miles wide.

Adding a GPS location squawk via satellite link would tell us nothing useful that we don't already know about its location (from air traffic control radar). It would also cost a metric fuckton to retrofit every commercial aircraft in the global fleet (approximately 20,000 airframes in service), and probably require a whole new satellite constellation to handle the data from 20,000 aircraft making an average of over 50,000 flights per day, especially if we wanted it to do something useful like upload the Flight Data Recorder and Cockpit Voice Recorder logs in realtime (so that in event of another AF447 we don't end up waiting nearly a year to recover the black boxes—and, in the case of AF447, requiring a nuclear submarine, a couple of deep ocean exploration vessels, and costing millions).

Or did you mean "lost" as in "crashed"? Airliners are already the safest form of transportation per passenger-mile ever invented; you're more likely to die on one of a heart attack or other natural causes than in a crash.

My understanding is that Malaysia Airlines offers pay cell service on select Boeing 777 flights, and that it would normally work at anytime during the flight that it's permitted. I don't claim to be an expert, though.

Personally, I don't have any view about this at this point--who does[?]--but it it seems odd to me to call that a conspiracy theory... Just sounds like a hypothesis to me.

I don't really know anything about air disasters--few of us probably do. All people can do in such circumstances is cast about for hypotheses. And the disasters most of us remember are, perhaps, not representative... So, perhaps that's a bad hypothesis from the perspective of someone who is knowledgeable... But from my perspective, anyway, it seems like one of the two or three obvious hypotheses.

Pilots on PPRUNE, my go-to forum whenever there's an air disaster, are commenting that the sea over which this plane would have flown is crowded with fishing vessels, so many that it sometimes appears to pilots as a city beneath them.

It will take a day or two but I suspect some of the people on those vessels witnessed something in the sky, even though it was the wee hours of the morning. Perhaps someone shot some video.

Stolen passports were used to buy two tickets for Malaysia Airlines missing flight - South China Morning Post

Two people named on a list of passengers on board missing Malaysian Airlines flight MH370 were not on the plane, but both had reported their passports stolen.

Foreign ministry officials in Rome and Vienna confirmed on Saturday night that the names of two nationals listed on the manifest of the flight matched those of passports reported stolen in Thailand.


China Southern, who jointly shared the route with Malaysian Airlines in what is termed in the industry a 'code share', said in a statement they had sold tickets to one Austrian and one Italian.


The revelations will raise questions over security at Kuala Lumpur's airport, and how the stolen passports were able to be used by people other than their rightful owners.

At a press conference on Saturday evening an airline spokesman refused to rule out terrorism as a possible reason behind the very sudden disappearance of the flight.

The stolen passports could have been used for the cause of terrorism.

Or the owners of the stolen passports might have been crime cartel members, drug runners, people in shady "import/export" businesses, or have some other not-particularly legitimate reason to launder their identities regularly, and had the misfortune to be on a doomed flight.

There's no reason to rule it out and no reason to leap to conclusions yet either.

For this to be a meaningful terrorist act, somebody will eventually have to make a claim and stake a cause.

A terrorist incident that's indistinguishable from an accident is ineffective terrorism. It is like silently boycotting something you would never buy. So if there is terrorism underpinning it, there will either be follow-up news from a recognizable authority about communications they've had, or communications directly to the press, addressed either to the public or to relevant government or businesses. I think it's reasonable to wait until then before assuming terrorism happened.

If the cause is to deter people from flying than our hypothetical terrorists have no need to stake claims and in fact would be better off not taking credit.

I am suddenly feeling a bit paranoid.

The presence of one stolen passport shouldn't be too surprising. They get stolen for a reason, after all: people want to travel without being detected (or for identity theft and fraud, but that's not in the frame right now).

However, it gets interesting because two stolen passports were used to buy two tickets, via China Southern (the flight being a codeshare operated by Malaysian).

The probability of one person with a stolen/fake passport being on a given wide-body is not high, but is non-zero. But the probability of two stolen/fakes independently showing up on the same flight is vastly lower.

Inference: the presence of multiple stolen passports on a single flight is very unlikely to be a coincidence.

Next up: if you're part of a group using stolen passports and you simply want to travel from A to B undetected, you probably want to travel separately. (If one of you trips an alarm, you'd prefer that only one was caught rather than losing everybody.) KL to Beijing is a daily or more-frequent service -- they're both major regional hubs. So there's no obstacle to doing that.

Second inference: the folks with the stolen passports wanted to be on the flight together, despite the elevated risk of interception. Which suggests that for their purposes group action was the goal, rather than relocation.

Am I reading too much into this?

You don't know what the probability is of one person with a stolen passport being on the flight, so you can't say whether two on the same flight is unusual or commonplace.

if you're part of a group using stolen passports and you simply want to travel from A to B undetected, you probably want to travel separately

Nobody found out that there were two people traveling with stolen passports until they started looking into what happened to the plane, suggesting it would have gone undetected otherwise, and therefore there was no need to be so cautious.

Am I reading too much into this?

In the absence of more information, I'd say yes.

Eh. Passports get stolen all the time. A lot of the world isn't equipped to confirm passports are valid at ports of entry/exit. Unless you've got some specific numbers on probability of someone traveling on a plane in SE Asia on a stolen passport that are really minute, it just seems like a coincidence to me. How many people fly on domestic American flights with illegitimate ID? Keep in mind that there have been repeated occurrences of state licensing offices having fraud problems where employees were selling "real" documents, not to mention the thriving industry in making credible fakes. Even with a pretty small rate of travelers using stolen / fraudulent documents, two of them on a 400 person plane is going to happen pretty frequently.

Also this is sad obviously. :(

I wasn't able to find even one example of a crash with one person with a stolen passport on it. And this would pop up right away, as the "victim" announced that they were still alive. You can certainly find plenty examples of crashes with victims carrying fake passports...

Pending another example of a crash with even one victim carrying a stolen passport, I'd agree with cstross that having two such victims is extremely unlikely and has a strong possibility of being connected to the cause of the crash.

There were 119 plane accidents in 2012 alone, with 794 deaths. Since 2001, the world has averaged about 1000 fatalities a year. (Source.)

Most of these crashes are regional jets, but that's still a reasonable sample size. Pending anyone demonstrating even one stolen passport on any other crash, I'd say that the existence of two such passports on the flight is still deeply suspicious.

The antecedent isn't guesswork - we have a large volume of hard data on plane crashes. Given that we have pretty detailed information about many previous crashes, and given that there wasn't(*) even one stolen passport on any of them, the claim that "having two passengers carrying stolen passports on a crashed plane is not improbable" does not seem correct.

(* - more precisely, that no one here has come up with any example of a stolen passport being attached to a plane crash victim. More data could of course invalidate the conclusion, if not the reasoning.)

Ok, lupus, using math, please explain how a sample size of 1000 a year globally, let alone 229 mostly Chinese passengers traveling from KL, is statistically representative of tens of millions of passengers who fly each year on international commercial flights. Remember your sample has to include only international flights, worldwide.

I am asking sincerely. I know stats but it's been a while since I brushed up. Your claim rests on a premise ("travel on false passports is so rare that that no such person ever died in a crash before") that implies very few people ever travel on false documents. Depending on your definition of "very few," I doubt it is so few that there aren't regular situations where two such people might wind up on the same flight, for example traveling together.

Also, where did you find proof noone has ever gone down with a fake passport? Just because no one has a counter-example handy here? I'm an aviation buff, and I'm not aware I've ever seen that remarkable claim made, or on what basis it could be determined quickly. Most accidents happen on domestic flights without passport control, so noone would even collect such data even if passengers had fake passports for when they did travel internationally. So your initial annual death statistic, which includes a majority who would not have needed passports at all, is incorrect.

We will know what happened. We almost always do. The speculation in this thread is sort of gross, as well as irrelevant to the truth.

List of (in my opinion mostly bullshit) theories on WhoDunit that I've seen floated:

* anti-Islamic Chinese
* Ukraine/Crimea/Russia
* the pilot is Muslim therefore he crashed the plane on purpose
* alien abduction
* something Bermuda Triangle-esque
* Conspiracy by Malaysian Gov to distract from current political climate
* Conspiracy to hide MAS financial losses
posted by divabat at 10:43 AM on March 8, 2014


Likeliest explanations based on history, in rough order of probability for complete hull loss at cruise altitude (or controlled descent into terrain from cruise):

* Catastrophic mechanical failure
* pilot error
* combination of mechanical failure and pilot error
* terrorist bombing/hijacking or pilot suicide
* flammable/explosive cargo improperly secured
* mid-air collision with so-far undocumented other aircraft
* missile strike from hostile source (it's happened a few times, KAL 007 and IR 655, for example)

(Weather doesn't seem to be an issue or it would be high on the list.)

The first three, plus weather, explain the vast majority of hull loss incidents over the history of aviation. If you really want to use statistical reasoning, it's one of those explanations to a very high degree of probability, with terrorism/missle strike/pilot suicide being a wild card since it requires intentionality and the others are accidental catastrophes. Statistics don't explain the probability of intentional actions against the normal human interest in surviving one's flight. It's not a risk one can exactly calculate since it depends on non-aviation-industry countermeasures like passport control or mental health screening, not to mention regionally specific political contexts and security protocols.

Why repeat baseless conspiracy theories here? Why speculate based on rumors and irrational explanations ("Bermuda triangle" lolwut)? We will know roughly what happened, almost certainly, fairly soon. It's a settled science, and investigators are very good at it.

The info about relatives being angry comes from here:
Relatives of those on the missing flight who were waiting at Beijing Capital International Airport were taken to a hotel and kept waiting in a room for hours, prompting complaints. One woman said no one from Malaysia Airlines had come to the room to talk to relatives.

[...]

At the Kuala Lumpur airport, a grief-stricken relative of a passenger aboard MH370 screamed uncontrollably as he was escorted out of the terminal by airline employees.

“Be truthful about this!” said the man, Koon Chim Wa, whose booming voice echoed through the cavernous terminal.

“They say they don’t know where the plane is,” Mr. Koon said, his hands and body shaking. “Is this a joke?”
I can't tell if your comment about levity is sarcastic or not - I can tell you that the Bermuda Triangle comment was met with a lot of horror by Malaysians.

If p(person with stolen passport on flight) = 0.01, then for two persons, p(stolen passport) * p(stolen passport) = 0.001. Elementary stats.

[morbo] ELEMENTARY STATISTICS DO NOT WORK THAT WAY! [/morbo]

Even if you want to treat it the way you implicitly were -- as independent draws -- you have to start with the individual pr(carrying stolen passport). Call that x.

We know there were 227 passengers, so the probability of exactly zero passengers carrying a stolen passport is

pr(zero)=(1-x)^227

and the probability of exactly one is

pr(one)=(x)(1-x)^226 / (227!/(1!*226!))

And the probability of at least two people carrying stolen passports is 1-pr(zero)-pr(one).

If we use robotvoodoopower's back-of-the-envelope estimate that x=0.0016 then (using bitesti in stata because online tools get stroppy about calculating 227!) the answer turns out to be 0.052.

I'm not being sarcastic. I just don't see what purpose is served repeating tasteless humor.

Every time a plane goes down under hard-to-recover circumstances, relatives of the dead are understandably upset and angry with the carrier and government officials and feel they are being left in the dark. It is predictable and completely understandable. The wait is agonizing and every passing hour means hope slips a little further. But usually the carrier and involved governments are doing all they can. Their colleagues were on that plane too. My guess is they just don't have any news to give yet. It takes time to do search and recovery at sea.

The arc of this is predictable and bog standard.

So I don't really buy that MAS or the Malaysian or Chinese governments are acting incompetent or corrupt, and I certainly don't accept that the expected angry relatives prove any such accusation.

As I said, MAS had a nearly perfect safety record and is highly regarded for competence and service by international business travelers.

Incidents like this bring our own fears (and ignorance) to the fore, when we have very few "facts".

As spitbull points out, the likelihood of this being a "terrorist" act are far down the list of probables--but are high on the list of immediate assumptions.

That in itself points out how effective terrorism actually is--when people are so frightened that every major incident is subject to endless speculation about terrorism, the terrorists have, indeed, won. Terrorism is also a justification for "othering" a lot of the time; there is a (repellent) tendency for some to immediately look for and then post as "ahas!" surnames and the like when those things are, at best, poorly correlated with actually being a terrorist.

I hope that whatever befell this flight was over quickly, and that folks on board did not suffer. I also hope their family and friends get quick closure to the mystery of what happened, but experience tells us that will take a lot of careful investigation.

Associated Press:
If there was a minor mechanical failure — or even something more serious like the shutdown of both of the plane's engines — the pilots likely would have had time to radio for help. The lack of a call "suggests something very sudden and very violent happened," said William Waldock, who teaches accident investigation at Embry-Riddle Aeronautical University in Prescott, Ariz.

Instead, it initially appears that there was either a sudden breakup of the plane or something that led it into a quick, steep dive. Some experts even suggested an act of terrorism or a pilot purposely crashing the jet.

"Either you had a catastrophic event that tore the airplane apart, or you had a criminal act," said Scott Hamilton, managing director of aviation consultancy Leeham Co. "It was so quick and they didn't radio."
posted by Chocolate Pickle at 2:36 PM on March 8, 2014 [1 favorite]


Yeah, that's the implication of a plane "crashing" while at cruise altitude. It takes an unfortunately awful amount of time for a plane to fall from the sky if it stops working which would give the pilots plenty of time to contact controllers. Given there was no radio call the implication is that either the plane exploded in flight, someone prevented the pilots from calling for help, or one of the pilots crashed the plane.

Likeliest explanations based on history, in rough order of probability for complete hull loss at cruise altitude (or controlled descent into terrain from cruise):

Spitbull: A bunch of the "highest probability" explanations you list fall way down in plausibility when you take into account the lack of distress call from the pilots. Pilot error does not cause a plane to dive into the sea from cruise altitude without any sort of communication. Mechanical failure, ditto. Unless that mechanical failure causes the plane to completely break up in flight, of course, but those are extremely rare kinds of failure.

Not really. Mechanical failure and pilot error have indeed combined to bring down planes in uncontrolled descent from cruise alt. look at Air France. No distress calls because they didn't realize they were in trouble until too late. Explosive decompression from a blown hatch can rip an engine off a wing too.

You can look at the history of lost hulls at cruise altitude and find more examples of rapid decompression or collision than terrorist bombs. There are plenty where no calls were made too.

Yeah, I don't mean that the airframe breaking up has to be the result of a bomb or anything. Just that the sorts of mechanical failure which lead to rapid decompression or the airframe breaking up are much rarer than the sorts of failure which can lead to a crash on takeoff or landing.
posted by Justinian at 3:11 PM on March 8, 2014


My point being that while those are indeed "rare" kinds of failure (since failure is rare anyway), bombs are even more rare.

I'm not placing bets one way or the other, but I think there are reasons to be calm about the terrorism possibility for now. Sure it's possible. It's always possible. But the passport derail was leading us into total speculation, is all I'm sayin'

Reuters:

"John Goglia, a former board member of the National Transportation Safety Board, the U.S. agency that investigates plane crashes, said the lack of a distress call suggested that the plane either experienced an explosive decompression or was destroyed by an explosive device.

"It had to be quick because there was no communication," Goglia said.

He said the false identities of the two passengers strongly suggested the possibility of a bomb.

"That's a big red flag," he said.

If there were passengers on board with stolen passports, it was not clear how they passed through security checks.

International police body Interpol maintains a database of more than 39 million travel documents reported lost or stolen by 166 countries, and says on its website that this enables police, immigration or border control officers to check the validity of a suspect document within seconds.

Like who? Any fisherman likely to be up at 2am is probably not looking at the sky, but lines, nets, ocean, charts, motors, other boats. Besides, a plane breaking up is not necessarily going to produce a big light-filled explosion. Light comes from materials igniting, but it just takes a breach of the plane's physical integrity for an explosive decompression event. That can be caused by a bomb, but also by physical failure of some part. Not all explosive decompression events cause the plane to immediately crash, but it is one of the possible scenarios in this case.

Interesting comment from here:

I'm troubled and puzzled by the two passengers travelling on fake/stolen passports.

>>>

Just as an aside, on a course in the '80s about dealing with major incidents with numerous fatalities, one of the lectures was by Kentons, who at that time, and perhaps now, undertook the task of identifying victims from whatever remains were available at most of not all such events in the UK.

One of the many memorable things we learnt was the fact that in every such event, about 5% of the victims will be travelling under false identities, or secretly under their own identities, or otherwise are not quite what they appear to be. The speaker cited an amazing dance troupe of young girls, who turned out to be entirely male. Others were travelling on false passports, and on every flight, it seems, there is at least one gent with a lady not his wife/partner, who was supposed to be somewhere else entirely (the gent, not the lady).

So I wouldn't be too troubled or puzzled by this (I'm puzzled about why you are "troubled"); it's pretty much normal and doesn't mean anything.


I'm sure things have changed somewhat since the '80s, but a bit of data nonetheless.

oneirodynia: that sort of reminds me of a discussion I've had with a couple of Twitter folks about how the nationality lists on the manifests could be misleading, as they're basing that on passports but these people may be residents of some other country. For example, had I been on a flight that crashed about five years ago, I would be on the manifest as 'Bangladesh' despite being for the most part functionally Malaysian - trying to contact the Bangladesh government to look for me wouldn't work well. (And also I'd be resident in Australia at that point so you're better off looking for me there.)

Then there's this 2010 article: At least 10 passengers of crashed Air India plane had fake passports


At least ten passengers on the ill-fated Air India Express flight from Dubai were using fraudulent passports, it was revealed. Police in Mangalore in southern India, where the plane crashed last week killing 158 passengers and crew, have now launched an investigation into every travel document used on the flight.


India’s ambassador to the UAE, MK Lokesh, said 10 passports had been “tampered with”. Irregularities included false addresses and photos that did not match the user. The investigation was initiated when a Dubai resident registered a complaint with the Indian consulate after his passport number and other personal details, including his address, were listed as belonging to one of the crash victims.

This is one of the reasons behind the push to including biometric identifiers and RFID chip in each passport. You could possibly replace the physical photo on a passport (though that is harder and harder to do), but if the passport had a RFID chip containing a digital image of the photograph as well, it wouldn't match the fake. Likewise, the person with the altered passport would not have the same biometric measurements as the original bearer, and so would be flagged at a properly-equipped passport control station.

From the Grauniad's live blog, regarding the two stolen passports:

Both passengers used Thai bhat to purchase their travel tickets on 6 March, a day before the flight took off from Kuala Lumpur destined for Beijing.

The pair, who booked tickets with consecutive numbers, were due to fly to Beijing, then wait for around 10 hours before flying to Amsterdam. Once they arrived in Amsterdam, one of the passengers was due to travel on to Frankfurt and the other to Copenhagen.

posted by daveje at 3:05 AM on March 9, 2014


The brief communication and the turning back suggest a mechanical failure, I'd say. I suspect the passports will turn out to be nothing but the normal noise of false identities. It's unlikely that any incident executed by humans would happen so fast that there would be no communications, unless Malaysian Airlines doesn't lock cockpit doors. No one is going to be able to personally transport on board a bomb big enough to cause instant vessel loss. And if it was a bomb in cargo or planted elsewhere, the bombers would hardly be on board.

daveje: I'll take the "stolen passports bought tickets with consecutive numbers" as support for my hypothesis that whatever their motivation, the passengers with those two stolen passports were working together.

Those two stolen passports bought tickets on MH370 for Thai Baht, the day before departure.

The tickets were KUL-PEK (Beijing), then a long connection window, then PEK-AMS. Then they diverged, one to Frankfurt and one to Copenhagen. The tickets were bought via China Southern.

This is a very odd routing if you want to fly to AMS on Malaysian, because Malaysian fly KUL-AMS direct. (I've been on that flight! In fact, Malaysian had four B777s, which mostly operated that route. There's about a 25% chance I was on the plane that crashed around this time last year ...)

Let us bear in mind that while Uighur separatists seem happier attacking railway stations with knives, Al Qaida spokesmen have denounced China as an "enemy of Islam" in the not-too-distant past.

Airline security in that part of the world is lax compared to the USA/EU. KUL operates gate security with cursory passport checking. I've no idea how easy it would be to get a suitcase onto the plane un-inspected, but AIUI checking is rather less thorough than over here. Maybe somebody thought that tactics that won't work here any more might still come in useful ...

My new hypothesis: if you wanted to get onto a Chinese airliner packed with Chinese folks flying to or from Beijing by using stolen passports without raising flags when you applied for a Chinese entry visa, this would be how to do it. The fact that it was a codeshare operated by Malaysian, in this scenario, suggests none-too-bright bad guys; that 75% of the passengers were Chinese suggests a motivation for them bringing the plane down anyway. ("Wrong airline, right target.")

I am now hoping even more desperately that this turns out to be an airframe failure -- possibly the spar of that wing that got damaged 18 months ago -- and the stolen passports belonged to smugglers or some other species of ordinary criminal, because the last thing we need is another round of global security theatre.

This is why I asked how he knew that was true, which he did not answer, as it seemed wildly implausible. We can't of course extrapolate from ten such people being in one accident in India just a few years ago either, but I imagine the math jocks can show us that this one case probably ups the probability of there being fake passport holders on any given international flight fairly significantly.

My reality says nothing about whether the supposed two fake passport passengers played a role in bringing down the plane.

The idea that traveling on false documents is so rare that it guarantees these two were involved in causing the accident is what I find absurd. Your comment above is entirely plausible.

It seems to me if the plan was to bomb this flight, then you don't need or even want two fake passport people to carry the bomb on board. It's redundant and doubles the risk of detection. It just seems less likely to me you'd put two of your team on a single-bomb, single-plane suicide mission. So, if bombing was the idea, then it seems more likely that the target was multiple connecting flights out of Beijing to European cities, and then one of the bombs went off prematurely. This also fits with comments I've seen that those stolen Euro passports would definitely be detected on entry through European immigration, even if they are fine for just getting around in East Asia. So as a means of getting into the EU they wouldn't be a smart choice.

An alternative is, if the passports have anything to do with it, then the fact there is more than one of them suggests an attempt to take over the plane with a team of hijackers. This seems unlikely since everyone knows that'll be harder to do post 9-11 between the cockpit doors and the motivated passengers. The brief turning back, if that is validated, is maybe suggestive of this alternative. And Kuala Lumpur has an attractive target if you're thinking of a repeat of 9-11. I doubt this is the case only because it seems so obviously seeing the present through the rear view mirror, and also would seem to have a low chance of success from the perspective of the attackers.

If the passports have nothing to do with this, and that's certainly possible, then truly it'll have to wait for the investigation. It could be some kind of incident paralleling one we already know about, whether Air France style crew fuckup, or the faultily-repaired wing on this plane catastrophically failing like that Japan airlines case from a while back, where a badly-repaired bulkhead failed years after it was "fixed". Or, it could be some completely new failure mode, though chances are there'd be hints of that found retrospectively (e.g., freezing pitot tubes were a known issue for Air France already, they just underestimated the risk).

The fact there was no distress call seems to not mean a real lot yet, since aircrew are taught to Aviate - Navigate - Communicate, in that order, so if you can't get past the first stage (fly the plane) you never get to the next ones.

The passport business is basically looking for your lost keys only underneath the streetlight. If there were any other facts to go on, I think the focus would be elsewhere.

No distress call means a rapid deterioration of the situation, but not necessarily an instantaneous one. The only scenario that I think it would argue against is a loss of power from both engines, which at cruise gives the pilots quite a bit of time to work with.

I don't know why people are using the phrase "explosive decompression". Loss of cabin pressure is not a significant threat to the safety of the flight, as it is a somewhat common occurrence as far as in-flight incidents go. Donning of oxygen masks and a descent to 10k feet is all that is required. Structural failure is however a threat to the flight, in which case decompression may be a symptom but is not really a cause.

The purported turn-back is compatible with basically any scenario you can imagine (including bad radar data) and has very little discriminatory power at this point.

"The mysteries surrounding the disappearance of Malaysia Airlines Flight 370, and the true identities of some of its passengers, are as deep as the southeast Asian waters where multinational search teams are searching for the jet." This is the bullshit writing we get when there's nothing to report.

I'm still confused about the source and quality of position reports. Initial reports were that the plane was entirely lost, like no one knew where in SE Asia it was. Later reports was that the plane had some automatic GPS uplink independent of the ground-based ATC radar systems. But the reporting I've read indicates they still aren't really sure where the plane was, much less where it is now. I guess the ELT isn't working either.

Part of the problem is radar doesn't have complete coverage, particularly over water. You really want some GPS fix communicated from the airplane itself. In the US at least position uplinks are still not required for aircraft. Largely because of air carrier recalcitrance, also because of the hugely inflated cost of aviation-approved electronics. The $99 + $150/yr Spot receiver in my pocket does mediocre position reporting to satellites, but the equivalent aviation systems cost $20,000+ per plane.

Yes, catastrophic structural failure is obviously a risk. The point is that the decompression part has little bearing on the airworthiness of the plane compared to whatever structural damage caused that decompression. Glancing at the list of incidents you linked, in every one I checked the decompression was a symptom, not a cause. E.g., KAL 902 - shot down by a missile, loss of cabin pressure not at fault. Turkish Airlines 981 - "The crash resulted from the rear cargo hatch blowing off, causing decompression and severing cables that left the pilots without control." Several others are listed as midair collisions, obviously not caused by depressurization. The fact is that loss of pressure is survivable as long as the damage that caused it doesn't otherwise impair the aircraft.

You really want some GPS fix communicated from the airplane itself.

I'm not really understanding why this position business is throwing everyone for a loop. The last known position, as reported in the aviation herald, was N6.9 E103.6. Presumably something very bad happened after that. I'm not sure what you expect the aircraft or radar or GPS to do after that point, none of them are magic and they all have their faults, and if this was an in-flight breakup then I wouldn't expect any of them to keep working. Sure a few more position reports would be helpful for the search, but they're not going to really tell us much more about the incident. This is where the ELT is supposed to take over.

Killedtaco, Well, yes of course something has to cause a hull breach to cause decompression. I never said decompression on its own was causal. Planes are built to minimize the risk of rapid decompression, but it happens and can be the proximate cause of further system failures and deaths from barotrauma or suffocation.

You said explosive decompression didn't happen to airplanes. In major hull breaches, it does indeed happen. I don't quite know what your point is. Something has to happen to cause decompression, but when it does, if the breach is big enough, it's categorized as "explosive." That is a thing that happens to airplanes, and it's likely what happened here (due to some other ultimate cause) since the debris field now appears to be widely scattered.

Metal fatigue, bomb, missile, collision, fire can all cause it. Obviously it doesn't happen independently of other damage.
posted by spitbull at 1:49 PM on March 9, 2014


And you're wrong about the effect of decompression too. It's likely what kills most people in a mid-air disintegration. A complete loss of all pressure at 35k feet causes rapid pulmonary barotrauma, and certainly contributes to structural integrity failure independently from the initial breach if the hole is big enough.

divabot: Some people are claiming that if the plane exploded mid-air there would be debris all over the place by now. Is that actually true?

I'm one of those people. Yes, if the passenger cabin is seriously disrupted at 30,000 feet then it would spray debris, much of which floats, over an area of tens of square miles. The fact that *nothing* has been detected in relatively clear weather argues heavily against this. There would be dozens of seat cushions, suitcases, and interior finishings floating around.

For the plane to go down without creating such a wide field of floating debris would require for it to be intact on hitting the water. For no debris to be found at all, as seems to be the case, would require the plane to hit the water mostly non-catastrophically, so as to also not disrupt the cabin too much on impact, so that such debris would be contained within the cabin as the plane sinks.

That could happen if the plane was under partial control, or if it was in an unrecoverable flat spin as it hit the water.

Adding a GPS location squawk via satellite link would tell us nothing useful that we don't already know about its location (from air traffic control radar).

Charlie: Reports today are that they're shifting their search from the South China Sea all the way to the Andaman Sea.... which is on the other side of Thailand. They think the plane "may have turned around" and crashed in a completely different location. So clearly a GPS squawk would be a lot more accurate than what they got from radar since they apparently don't even know where the plane went down within a hundred miles.

I'm kinda wondering if that whole thing regarding the Andaman Sea / Straits of Melaka is a bit of a token effort - Malaysia obviously has a whole pile of boats on that side of the peninsula, and want to put them to use doing something. I find it incredibly difficult to believe the plane could have turned around, made it all the way back across Malaysia / Thailand, without it communicating or being picked up on radar somewhere across the peninsula. But then the whole thing is awfully, depressingly strange.

Malaysia Airlines' primary focus at this point in time is to care for the families. This means providing them with timely information, travel facilities, accommodation, meals, medical and emotional support. The costs for these are all borne by Malaysia Airlines.

Initial financial assistance has been given out to all families over and above their basic needs.

At least one caregiver is assigned to each family. These caregivers are well-trained staff and volunteers from Malaysia and other organisations.

As of now, there are more than 150 "Go Team" members consisting of senior management and caregivers at Beijing to attend to these families. In Kuala Lumpur, a different group of caregivers are attending to the families’ needs.

Families from other nations apart from China have been arriving at Kuala Lumpur since early yesterday. More are expected to arrive today.
That is great. Those poor, poor people. I can't imagine the anguish they are in.

Internal Probe On Immigration Dept Commences - Zahid:
Home Minister Datuk Seri Dr Ahmad Zahid Hamidi said the detailed investigation would give special attention to the department's Kuala Lumpur International Airport (KLIA) branch.

"We will conduct an internal probe, particularly on the officers, who were on duty at the KLIA Immigration counter during flight MH370.

"I am still puzzle how come (immigration officers) cannot think, an Italian and Austrian (passengers) but with Asian facial features," he told reporters at the Kembara Bumi Suci 2014 convoy participants meeting with Prime Minister Datuk Seri Najib Tun Razak at Seri Perdana here Sunday.
I was so hoping this was a hoax when I read a reference to this on another news site, but it seems not! I'm not sure where he's getting the 'Asian features' from, or why he thinks Asian-looking people can't also have European names, but I'm not entirely surprised that this attitude exists either.

In fact, it isn't the airline itself that's actually sending staff out there and searching - as we've seen so far, it's primarily the navies of the countries involved. I hardly think that MAS maintains such capacity for search and rescue operations year-round. It makes so little sense, then, for them to 'focus' on something they can't do anything about at all, and sit there twiddling their thumbs.

From the New Straits Times:

Vietnamese searchers on ships worked throughout the night but could not find a rectangle object spotted Sunday afternoon that was thought to be one of the doors of a Malaysia Airlines passenger jet that went missing more than two days ago.
Doan Huu Gia, the chief of Vietnam’s search and rescue coordination centre, said Monday that six planes and seven ships from Vietnam were searching for the object but nothing had been found.

This is the possible "door with window" that was spotted by a search plane just before sunset last night (March 9) which boats were not able to look for until this (Monday) morning.

Not the possible "yellow" debris that was spotted yesterday during the day which a search vessel reached about 7 pm last night and determined it was not MH 370-related.

I don't know where he's getting it from either (as far as I know there has been no public information about who was flying on those tickets?) but two people with Asian features flying together on passports from different European countries with European names would certainly be enough to flag them for further scrutiny such as checking if the passports have been stolen.

Baggage being removed from a flight because a passenger doesn't board is not uncommon. On a recent flight from JFK to Montreal we'd already pulled away from the gate when it was determined that a couple passengers hadn't boarded, but their baggage had been put in the cargo hold. We had to return to the gate and wait for a good hour for handlers to locate the baggage and remove it from the plane before we could take off. I recall the pilot saying this regulation applied only to international flights, but I may be misremembering.

I've been reading a bit about China Airlines 611, a 747 which suffered explosive decompression in 2002, killing all 225 people aboard. Like MH370, Flight 611 disappeared from the radar without any distress call. And also like MH370, which supposedly suffered previous damage to its wing, Flight 611 had sustained damage in a tail strike incident years earlier. 611's tail was improperly repaired, but it held for 22 years of flights until fatigue caused its catastrophic mid-air failure. The debris was located two hours after the disaster, and only 15% of the wreckage was recovered.

By all accounts, MAS's maintenance practices are substantially better than China Airlines' were, but if those reports of the MH370 aircraft's prior wing-strike accident are accurate, it wouldn't surprise me if a similar structural failure were responsible. It strikes me as being much more likely than silent foul play, in any case.

It would surprise me. A tailstrike is typically a violent and forceful action against the "spine" of the aircraft. On the other hand, I can't think of many things that could go wrong with a wingtip that could cause the instant and total destruction of a modern airliner (especially during a point of the flight when there is minimal load on the wings). The wings of a 777 are ridiculously strong.

This is absolutely something that should (and will) be investigated if the plane is located and recovered. However, until that point, any idle speculation is just that.

We have literally nothing to go on. Each of the theories being tossed around are almost beyond implausible.

Not a wing tip, a wing. Concentrating the impact force at the tip means you're applying the maximum bending moment possible for that amount of force across the wing spar. And yes, that static test looks impressive, but it's not telling you what happens if you just bend it 70% of the way to breaking and then go on to fly it for another decade or 2 under non-abusive conditions. These sorts of incidents affect the fatigue life.

"not decompression. It is not itself an event which can cause a loss of the aircraft."

Right, we agree on this. So maybe we are arguing in circles without agreeing on the meaning of "cause." Rapid, explosive decompression following hull damage caused by impact or bomb could potentially render the crew unable to communicate because they would be unable to breathe and be unconscious in a matter of seconds.

In most accidents, there are ultimate causes (a bomb, a missile, a collision, a mechanical failure, a pilot error, weather), and then there are proximate causes that escalate the situation. Among the escalating factors, fire and decompression are major ones, and can cause human effects that render the ability of the plane to keep flying moot. Pilots don't wear oxygen masks normally, so a structural failure at cruise altitude could cause pilots to lose consciousness really rather immediately. Like in seconds. That's why the degree of decompression (the size and location of the hole, effectively) matters. Same with a fire in or near the cockpit.

Most air disasters have multiple causes, usually including pilot errors in responding to the initial crisis out of stress or lack of preparation, or most commonly, communication failures in the cockpit (of the sort that also might preclude sending a distress signal, although why autobeacons wouldn't come on is mysterious).

The point at which they become unsurvivable may be well past the point where the crisis begins. Decompression is often a factor in that. Your plane can still fly, but no one is alive to fly it.
posted by spitbull at 2:27 PM on March 10, 2014


AF 447, for example, was not doomed the moment the pitot tubes froze over. It was doomed by the way the crew responded and failed at cockpit resource management, as all analyses I've seen agree. That was a survivable crisis.

Yeah, if you want to scare the fuck out of yourself, read the transcript of the AF447 accident cockpit communications. It was an utter fuckup, a failure of tried and tested CRM procedures, and an example of how the very best technology (although one could argue that the non-synched controls for P and CP on the A330 were a technological failure too, as were the faulty pitot tubes) is no defense against human error.

Even highly trained people lose a lot of edge under severe stress. That transcript is one of the saddest things in aviation history. No one needed to die on that flight.

And that's my point. Most accidents do not have a single proximate cause. Usually, crews have time to radio a distress call or hit the beacon, but sometimes they get so caught up in trying to understand the immediate crisis that they forget their training.

I got curious & googled wing flutter. NASA's Langley Rsch Center's YouTube page has a bunch of old flutter test videos that show (less modern!) planes hitting "Galloping Gertie"-like resonances and flying to bits, sometimes after only a few oscillations. Needless to say, modern aircraft are designed to dampen such oscillations and are extensively tested both in simulation & real life; here's a neat video of Boeing's flutter test of its new 787 Dreamliner.

I have absolutely no idea what happened in this tragedy, but I can certainly imagine how the loss of a wing-tip, and the resulting turbulence around the blunt edge, could compromise the 777's ability to damp aeroelastic flutter.

posted by travelwithcats at 4:31 PM on March 10, 2014


travelwithcats, I think you're confounding a couple of things. A "black box" is the Flight Data Recorder, the thing that's supposed to record what happened to an airplane to be recovered after an accident. They have been enormously useful to researchers to figure out what caused a plane crash. Recovery is not easy; it took two years to pluck the black box for AF447 from some 10,000 feet underwater, for instance. Closely related to the flight data recorder is the Cockpit Voice Recorder. In AF447, at least, they were separate boxes.

The Fox News article about plane tracking is talking about the ADS-B transponder, the thing on the airplane that's actively broadcasting the plane's identity during flight. There's a variety of transponder technologies in use right now. Long story short, airplanes mostly broadcast their identity, altitude, and (if you're lucky) GPS position and velocity. Those transmissions are designed to be picked up by ground stations for air traffic control and, in some circumstances, other airplanes. These transponders are the primary way ATC knows where airplanes are; passive radar is only secondary. We're in the middle of an FAA clusterfuck to upgrade these systems, I don't know the status of international law. But in general transponders work pretty well. What happened to the Malaysian plane's transponder signal is a central mystery that the black box may eventually unravel.

That Guardian article you linked is arguing that at least some of the data recorded in the black box should also be broadcast live from the plane during flight, so we don't have to recover the recorder to know what happened. That's a sensible enough idea, although as they say it's expensive and awkward. Something like that already happens now by the air carriers; IIRC Air France already had a fair amount of data from AF 447 the day it crashed thanks to engine monitoring, etc. (References welcome!)

I've been arguing something similar, which is that airplanes should be broadcasting their ADS-B information to satellites. In particular position data. And, this is key, up to satellites in orbit; not just down to ground stations. That way you get position coverage no matter where the plane is, in a global ATC system. There are a variety of technological and economical barriers to doing this, but I think it's doable.

It's not clear any of this discussion of transmitters on the plane is relevant; the lack of any voice radio communication from the pilot suggests no transmitter in the cockpit would have worked. Which then raises the question of the ELT, the emergency transmitter that's supposed to activate when a plane crashes. Modern ELTs include GPS receivers and broadcast identity and position data to satellites at 406MHz. They're also designed to work even in a catastrophic incident. Why there's been no ELT from this Malaysia Air flight is another mystery.

Can it be inferred that on the Helios flight the passengers were all dead of aphyxiation before the crash? The plane had 12 minutes worth of oxygen for passengers, the flight attendant had a portable oxygen canister. What a macabre scene that must have been.

Yet strangely better than the long silent glide after the engines cut out.

Kinda off-topic, but: I fly internationally maybe once per year. I check in online because...I don't know. I have absolutely no idea why I check in online. When I get to the airport, I still have to wait in the check in line in order to check my bags in. Online check-in, as far as I know, doesn't save me any time or effort or anything.

So, I guess, two part question: Part I: Am I missing something? Is my online check-in somehow offering me a convenience I'm not even aware of? Part II: Are there a lot of people like me who don't understand the point of online check-in? Are there any current or former MeFi airport workers who can estimate what percentage of people check in online vs. at the airport?

I check in online in case I can get a better seat, make sure there haven't been any changes in timing or anything, and to try to ensure a vegetarian meal. (Someone once told me that if they overbooked I'd be in a more advantageous position for having checked in early, but I don't think that's actually true.) I feel like it's slightly faster and it means I have to groggily talk less to people, but I don't know that it makes a huge difference.

Another interesting thing from that Prune forum is that one of the other major incidents involving a 772 was a cockpit fire that thankfully started on the ground. AvHerald has a report, along with pictures. The damage to the controls is astonishing. A fire like that might well be able to incapacitate a plane fast enough to mean no messages were sent, since it would burn the pilots to death to burn them until they flee to the temporary safety of the passenger cabin.

Oh, and the fire hypothesis has the added implications that the plane wouldn't have needed to broken up before it went into the ocean. Given the lack of debris field being found thus far, it doesn't seem like the plane disintegrated at 35000 feet, but rather nosedived into the water making as small a footprint as possible.
posted by barnacles at 7:43 PM on March 10, 2014


I believe they don't yet know for sure what caused that fire, but it involved the copilot oxygen line and burned hot and fast. Had that happened at altitude the pilots would have burned alive, or if not, and they had extinguished, their oxygen system would have been useless with a big hole under their feet. Seconds to loss of consciousness.

Creepy as fuck.

Missing Malaysia Airlines plane: Search now focused on west of Peninsular Malaysia: Official

The search operations for the missing Malaysia Airlines jetliner is now focused on the west of Peninsular Malaysia in the Strait of Malacca, as no signs of the plane has been found in the South China Sea, officials said.

"The search and rescue teams have expanded the scope beyond the flight path. The focus now is on the West Peninsular of Malaysia at the Strait of Malacca," Malaysia Airlines chief executive Ahmad Jauhari Yahya said in a statement on Tuesday.

He said the authorities are looking at a possibility of an attempt made by flight MH370 to turn back to the Subang airport in Selangor, about 50km from the Kuala Lumpur International Airport.

If the two passengers who traveled using stolen passports did effect the destruction of flight MH370, how will governments attempt to close this security issue?

I am concerned there will be calls for biometric scanning.

If we discover the disappearance of flight MH370 was the result of an act perpetrated by the two passengers using stolen passports, I hope we will have the collective sense to reject any calls for biometric identification at the ports through which we travel.

There already is a way to avert these kinds of situations - Interpol's Stolen Passports Database - the problem is that many countries don't use that database enough when checking in people (and they're pretty annoyed about that).

SkyNews Australia: Stolen Passport Held by Asylum Seeker

A man travelling with a stolen passport on a missing Malaysia Airlines jetliner was an Iranian teenager trying to migrate to Germany, and is not believed to have any terrorist links, police say.

The announcement is likely to dampen, at least for now, speculation that the disappearance of the Boeing 777 was linked to terrorism. ...

News that two of the passengers were travelling with stolen passports immediately fuelled speculation of foul play. However, Malaysian police chief Khalid Abu Bakar told a news conference Tuesday that investigators had determined one was a 19-year-old Iranian, Pouria Nourmohammadi Mehrdad, who was planning to enter Germany to seek asylum.

'We believe he is not likely to be a member of any terrorist group,' Khalid said.

He said the young man's mother was waiting for him in Frankfurt and had been in contact with police. He said she contacted Malaysian authorities to inform them of her concern when her son didn't get in touch with her.

Now at 22:20, the Deputy Minister of Transport has requested clarification from Malaysia since it looks like the Malaysian government has sat on this information for two days during which time Vietnam, in the spirit of cooperation, had allowed two Chinese navy ships to enter their territorial water, despite ongoing diplomatic tension between the two countries.

Yeah, I actually think a Helios or Lear Jet-type scenario sounds plausible. The longer the search goes without recovering anything, the more it appears the plane might have flown for a significant time after the reported last radar contact. If that is the case, then an abnormal response to an abnormal situation starts to sound like likely option, rather than the catastrophic failure/fire/bomb/etc scenarios. Or really, knowing nothing else about the incident our prior should always be a series of failures, but this one seemed so weird that it temporarily overrode that.

If true, it does seem to bring the possibility of human intervention back into the mix. Would it be possible to simultaneously have a power failure that cut off all beacons and communication, a decompression or cockpit fire that took away human control (at least, if the pilots were still flying, I would have expected they would divert to the nearest airfield after such a power failure) and the plane *still* fly for a hour?

Well, I know that a decompression incident could definitely lead to such a flight, so I guess the question would be how plausible it would be to have the transponders/beacons knocked out as well. Are they purely run off the plane's power system or does it take something else to put them offline?

Missing Malaysia Airlines Flight MH370: Passengers' Mobile Phones Ring But Not Answered

That phone ringing story seems to be based on an understanding of how telephones works that hasn't really been true since landlines were dominant. Hearing a ring while calling a cell phone doesn't imply anything about what's happening on the receiving side. It's a little unusual that it doesn't go straight to voice mail, but there are a lot of reasons why that may be. One may be that the system which provides service on the plane provides the appearance to the network that users are connected to an actual physical cell somewhere, while in reality, that connection is being relayed through a satellite network and is non-deterministic. None of the major news outlets with this story could find an expert who knows how this stuff works for sure?

The phone rings because the phone company routes the call to the last place it pinged, then tries to locate the phone by other cells before it routes to voicemail. That takes time, and if it were silent during those transfers people would just hang up.

It seems unlikely that they were pinging against physical cell towers vs. a "virtual" cell contained within the plane and connected via satellite. That's how the systems I've seen in the US work, but I'm not an expert on them nor do I know if this plane has the same kind of system. It's possible they could've pinged a real tower while over land, of course.

So how long does a big airliner have to be silent before people start going "hm"? I would have thought that was a period measured in minutes. (By silent, I mean any form of active communication from the jet, whether it's a ping to a satellite or ground receiver from onboard data transmitters.)

I think oneirodynia has it probably right. I think the phone ringing has to do with the phones having last connected to an overseas network and therefore the home network has to do some routing before it can work out if the phone is available.

There may also be idiosyncrasies to the Malaysian/Vietnamese/Chinese mobile network that cause this.

Only someone familiar with the mobile phone systems of at least Malaysia and China, and any mobile phone routing done via the airplane could say for certain what the phones ringing means.

However...
(Reuters) - Malaysia's military believes a jetliner missing for almost four days turned and flew hundreds of kilometers to the west after it last made contact with civilian air traffic control off the country's east coast, a senior officer told Reuters on Tuesday.
So, not by Berita Harian but maybe someone who reads Berita Harian? Also is a Facebook post by a Defense Journalist how one normally disseminates this information? The New Straits Times only got around to posting the BH story an hour and a half ago. The Straits Times at 8:28 PM.

It's also interesting combined with this article:
Four days after flight MH370 went missing in mid-air with 239 people on board, no nation has stepped forward to initiate and lead an official probe, leaving a formal leadership vacuum that industry experts say appears unprecedented.

Malaysian officials are conducting their own informal investigations, in cooperation with other governments and foreign agencies, but they lack the legal powers that would come with a formal international probe under UN-sanctioned rules...

Those powers include the legal rights to take testimony from all witnesses and other parties, the right to have exclusive control over the release of information and the ability to centralise a vast amount of fragmentary evidence.

Without a formal investigative process being convened quickly under rules set out by the International Civil Aviation Organization (ICAO), a UN agency, there is a risk that crucial early detective work could be hampered, and potential clues and records lost, air accident experts said....

A lack of clarity over the investigation already appears to be a source of tension between Malaysia and China, which had up to 154 citizens on the Beijing-bound flight and is pushing for a significant role in the investigation.

China's Foreign Ministry urged Malaysia yesterday to step up its search efforts and start an investigation "as soon as possible and correctly".

The deputy head of China's civil aviation authority urged Malaysia to help a team of investigators it has said is ready to fly to the Southeast Asian nation to help with the probe....

The official familiar with the preliminary Malaysian investigation said the Malaysian government could not launch a formal probe until the crash site had been found, and that it planned to work closely with US authorities and Australia.

Witnesses such as cargo handlers, mechanics and company officials might be reluctant to speak to Malaysian investigators who were operating outside a formal ICAO-sanctioned probe which could offer them some protection from law suits, experts said...

The lack of a formal investigation also means Malaysia does not have exclusive control over the release of information...

Someone expert in aviation: would the RAT deploy automatically in the event of a complete loss of engine-driven electrical power at cruise altitude without a pilot throwing a switch?
posted by spitbull at 11:42 AM on March 11, 2014




OK, this is just weird and I hope it's bullshit, but there is a report the pilot of MAS370 (at the time a copilot) had allowed (and in fact invited) two attractive young women to ride in the cockpit for the entire duration of an earlier international flight, takeoff to touchdown, and that the pilot and a different copilot had tried to get the women to stay with them for a few days in KL. What's more, the women report that the cockpit crew smoked throughout the flight. Which is like fucking crazy.

My understanding is that Malaysia cannot open an investigation yet because they do not know the country in which the accident occurred, which by ICAO procedures should lead the investigation.

And yes the RAT deploys automatically in the event of power loss on both AC busses, dual engine failure, or all three hydraulic systems pressures low (confirmed with boeing docs).

Here, I'll reproduce that 13th statement to save people a click:

Tuesday, March 11, 11:30 PM MYT +0800 Malaysia Airlines MH370 Flight Incident - 13th Media Statement

Malaysia Airlines has become aware of the allegations being made against First Officer, Fariq Ab Hamid which we take very seriously. We are shocked by these allegations.

We have not been able to confirm the validity of the pictures and videos of the alleged incident. As you are aware, we are in the midst of a crisis, and we do not want our attention to be diverted.

We also urge the media and general public to respect the privacy of the families of our colleagues and passengers. It has been a difficult time for them.

The welfare of both the crew and passenger’s families remain our focus. At the same time, the security and safety of our passengers is of the utmost importance to us.



ACA is showing photos that appear to confirm at least the basis of the story, and would seem hard to refute, of Fariq, the pilot, and the two young women with their arms around each other having a blast, with the comely Jaan Maree wearing the co-pilot's cap.

And no, of course, divabat, I agree. My main riff here is that hoofbeats mean horses not zebras until proven otherwise. The claim is so outrageous it would take more than a photo in the airport lounge to convince me, for sure. But there are going to be witnesses, and other people these women told the story to soon afterwards, if it happened.

On the surface of it, it's hard to figure out why anyone would make something like this up, though. The woman they interviewed seems believable to me, but also sort of used to getting treated special because she's so attractive, which gives her the blasé "yeah, it happened, it didn't seem like such a big deal, of course we went along because it's a cool opportunity most people wouldn't get."

But I utterly agree: prove it incontrovertibly, which they should be able to do, or it didn't happen. I'm sure the flight attendants would have noticed this if it happened.

Could someone explain more about ICAO procedure? I don't understand why the default provision, in case of a disappearance, is that there'd be a clear designation of who should run things until discovery jurisdiction, or whatever, comes into play. I'd imagine that it would be something like "until further evidence, the country of departure [or country of airline?] runs things." Is that not what happens? Is it complicated by the tensions in this region in particular, and/or is Malaysia ill-equipped to run this search and investigation?

It's not particularly remarkable that people fly on stolen passpoprts. And it's still unremarkable that when you call someone's cell phone, it rings, even if it's off network.

Some major revelations today: The pilots turned off the plane's transponder, then turned nearly around and flew back across the Malaysian peninsula and made it all the way to the Strait of Malacca before crashing. No one knows why they might have done that. (Evidently the authorities have known this for a while without revealing it, and that's why they've been searching in the strait.)

With their transponder off, the jet wouldn't have been visible on normal traffic control systems; only things like military radar could have tracked them.

Also, the two stolen passports were used by two Iranians, one 18 and one 29.

The RMAF has not ruled out the possibility of an air turn back on a reciprocal heading before the aircraft vanished from the radar and this resulted in the Search and Rescue Operations being widen to the vicinity of the waters of Pulau Pinang.
Note that Berita Harian and co are reporting that it's at Pulau Perak, while RMAF is saying that it may be in Pulau Pinang, two different places.

I'm not sure if this has been mentioned here yet, but do we have any examples of large jets disappearing and wreckage never being found? Today's WSJ says the last precedent was in 1962...

"In 1962, a Military Air Transport Service charter operated by Flying Tiger Line carrying 107 passengers disappeared on a flight from Guam to the Philippines. The Lockheed L-1049 Super Constellation was presumed to have crashed, but the wreckage was never recovered. According to the Aviation Safety Network, the search covered 144,000 square miles using 48 aircraft and eight surface vessels."

Third-hand via TPM:

Basically it's totally unclear what happened. But pilots who are discussing this on the cable nets point to another possible scenario: If the plane experienced a total loss of electrical power, that would turn off the transponders. But it would also allow the plane to keep flying, at least for some period of time.

So perhaps the plane experienced electrical failure, knocking out all communications and telemetry from the plane, the pilots turn around but somehow get lost and the plane eventually goes down.

Again, to be clear, that [is a] hypothetical sketched out by a highly experienced pilot. But purely a hypothetical based on an almost unprecedented and hard to interpret collection of data.

Yeah, I don't think the scenario on TPM makes sense unless some sort of decompression rendered everyone unconscious. One, for the reason you bring up. Two, the plane supposedly flew all the way across Malaysia and over the Andaman sea. If the pilots were in control and trying to recover from a loss of electrical power they would have tried to land somewhere rather than fly all the way across the landmass.

If you were making a Spy Adventure Movie Starring Top Actor, is there a plausible scenario where you could "steal" a 777 mid-flight by making it look like it vanished? Something like turning off everything that pings, taking it down to wave-top level and then hightailing it to your favorite handy abandoned airfield?

While unlikely, I had a similar thought today...and took it further with speculation on what could be done with a stolen 777. This isn't really speculation on this flight, which is absolutely tragic. But if one of these planes was stolen in this manner, what are the odds it could be later used as a weapon? With a traditional missile you'll light up radar screens like no tomorrow...but with an airplane, you have range and potential abilities to spoof a legitimate flight path. It's essentially a giant trojan horse that could be equipped with numerous kinds of payloads (chemical, nuclear, etc)

Again I don't feel that's what has happened here...but judging on how the response has been handled, and the complexity of the search...what once seemed unlikely to me suddenly seems plausible..and that's unsettling.

This seems like a decent theory:

PPRUN - 'onetrack'
Let's say an oxygen bottle in the cabin exploded and caused major decompression, and took out a heap of electrical wiring and comms, including the transponder.
The crew immediately commenced a left turn to return to KL and initiated a rapid descent. However, hypoxia took over prior to reaching a low level and the crew became unconscious. The aircraft continued to fly in a gentle arc, back over the Malay peninsula, at a steadily reducing height, or at a low height preset by the crew on the AP.

In that case, there's a strong possibility the aircraft crashed into the Gunung Leuser National Park - one of the largest, largely unpopulated, mountainous wilderness areas in Northern Sumatra. An aircraft crashing into a high-elevation area of this park at 3:00AM local time would be heard by very few people - and it would disappear into the jungle just as GOL 1907 did.

The Chinese are supposed to be using their satellites too but have not heard anything re that.

The thing to remember about satellite imagery is that if it detects a 2.5m x 2.5m object, that object will occupy a single pixel and won't be identifiable, so with a satellite of that resolution you'd be hoping to see a fairly significant debris collection. The higher resolution the satellite (you'd really be hoping for something with sub-meter resolution), the smaller its field of view, and the less frequently it passes over a given spot on the Earth. So unfortunately, it's not as simple as getting the high-resolution satellites that take the kind of imagery you see on Google Earth to take images of the whole ocean in the area. It might be weeks before they swing past again.

I for one had understood that they had detected something but were not sure what but it could have been the plane, having crossed the peninsula. Journalistic echo chamber where everyone reports on any detail until it gets amplified and distorted seemed to have turned it into: "MH370 tracked over peninsula".

From the WSJ:
U.S. investigators suspect that Malaysia Airlines Flight 370 stayed in the air for about four hours past the time it reached its last confirmed location, according to two people familiar with the details, raising the possibility that the plane could have flown on for hundreds of additional miles under conditions that remain murky.

Aviation investigators and national security officials believe the plane flew for a total of five hours based on data automatically downloaded and sent to the ground from the Boeing Co. 777's engines as part of a routine maintenance and monitoring program...

The engines' onboard monitoring system is provided by their manufacturer, Rolls-Royce PLC, and it periodically sends bursts of data about engine health, operations and aircraft movements to facilities on the ground.

Rolls-Royce couldn't immediately be reached for comment.

As part of its maintenance agreements, Malaysia Airlines transmits its engine data live to Rolls-Royce for analysis. The system compiles data from inside the 777's two Trent 800 engines and transmits snapshots of performance, as well as the altitude and speed of the jet.

Those snippets are compiled and transmitted in 30-minute increments, said one person familiar with the system.

If an aircraft, lost over the ocean and out of contact with all other forms of communication can send real-time data to Boeing, why isn't sending a bit of GPS data too?

Would my assumption if that is indeed true, the likely direction was SW? I would think anything over populated areas would have been noted.

And wouldn't a series of pings from the engines provide data, even if crude, as to direction and distance? I would assume (always a danger), that where the ping was received and it's strength would be part of the data. Hell, if I was RR, I would have GPS or something similar built in to the data, just for additional data when trying to debug anomalies.

Speculation about the Iranian dudes with the fake passports specifically or terrorism in general? I don't see why speculation about terrorism is inherently xenophobic although it ends up that way in practice far too often.

I wish somebody would confirm with certainty whether the plane was flying for hours after the transponders went offline. Either it was picked up on radar or it wasn't. If it wasn't, we are still stuck with "we have no idea whatsoever what happened". If it was we're really down to two theories. One, some sort of catastrophic failure which resulted in loss of electrical power to the transponders and rapid decompression which rendered the flight crew unconscious... but did not cause the plane to crash rapidly. Or two, some kind of hijacking situation.

It's hard to come up with other plausible scenarios where the transponders go offline but the plane flies around for 4-5 hours anyway.

As part of its maintenance agreements, Malaysia Airlines transmits its engine data live to Rolls-Royce for analysis. The system compiles data from inside the 777's two Trent 800 engines and transmits snapshots of performance, as well as the altitude and speed of the jet.

A few notes:

- This is primarily a Rolls-Royce thing, the data does not go to Boeing. It's a bunch of engine details, and since Boeing neither manufactures nor supports the engines, they don't have much of a part. The reason RR does this is because they frequently own the engines even when they're hanging on the airliner, and the airline pays RR for "power by the hour". This lets the airline focus on airline-things rather than detailed engine-things, and leaves the engines to the experts. RR tends to do this more than GE or PW.

- The engine data is transmitted via ACARS, which usually goes over VHF radio when possible (over land), but can also go over shortwave (over the ocean). There might be a satcom link too. This is where the first information about AF447 came from, prior to finding the black boxes. The 777 definitely has all this, as do almost all modern airliners. Exactly what sort of transmissions are enabled varies by operator.

- Most importantly: if someone is sitting on ACARS transmissions that were sent hours after the last radar contact, holy shit, that's a huge huge deal and needs to be made public right now.

Boeing and NTSB confirmed the last data transmission received from the aircraft was at 01:07L.

No, what Acting Minister of Transport Hussein said was:
I would like to refer to news reports suggesting that the aircraft may have been flying for some time after the last contact. Those reports are inaccurate.
It's a war of words now. Neither Boeing nor RR will make a statement regarding the data although Hussein stated: "Since today’s media reports MAS has asked Rolls-Royce and Boeing specifically about the data. As far as Rolls-Royce and Boeing are concerned those reports are inaccurate."

If we're talking about a scenario where everyone on board the plane was incapacitated fairly quickly, but the plane kept flying until it ran out of fuel, that suggests a few possibilities:

1. The slow decompression scenario, where the crew doesn't realize what's happening until it's too late, tries to turn back, and then passes out before they can complete the turn. Plane full of dead people flies for thousands of miles until it crashes into the ocean. This scenario has the advantage of having actually happened before, only not on this scale.

2. Pilots incapacitated, reinforced cockpit door holds despite all attempts by passengers and crew to force it, plane runs out of fuel. What could incapacitate the pilots like that? The passengers and crew would have several hours to work on the door. Could the cockpit door hold up that long? Would there be a way the crew could try to communicate with the outside world that would be accessible from outside the cockpit?

3. Terrorism. Could a shoe bomber, for example, blow a big enough hole in the hull to decompress the cabin and kill the crew before they could communicate? How much nerve gas would it take to kill everyone on board?

4. Theft. Hijackers quickly take over the plane, fly it to an out-of-the-way airstrip, land, then use their new 777 for nefarious purposes. There are many problems with this scenario. You'd have to control the passengers for a long time to get where you needed to go, and then make provision for them once you've landed. Maybe it would be easier to just kill them in the air. Can you do that without killing yourself, too? How do you navigate to the secret airfield undetected? How do you hide an airfield big enough land a 777 from satellites? How do you hide a 777 once it's on the ground? Remember, if this airliner is going to be of use to you in the future, you'll have to take off again. That implies a lot of support equipment, which only makes the stealth problem harder. This is Bond supervillain stuff. It would require months, if not years, of preparation with plenty of opportunities to be discovered along the way as you hew the runway out of the jungle and try to buy and get the support equipment in place. The only point in the favor of this scenario is that there is a lot of potentially usable land within 2,000 miles of the plane's last known location.

Slow decompression seems incredibly unlikely. The pilots would notice (and almost certainly be aware of the previous accident involving a 737 to ignore any alarms to that effect, or ignore the automatic deployment of oxygen masks).

WaPo is also reporting the 4 hour thing. No word on where that data came from (so.... most likely some military or intelligence program that nobody wants to talk about in any detail).

From reading the helios 552 investigation it seems the crew have a emergency access code to open the flight deck door:

Frankly, I am getting very suspicious of all the news reports quoting unnamed "officials". There is no way for us to evaluate the reliability of these comments and many times it seems journalists have misunderstood the nature of these comments. If these "officials" want to comment, why not make actual official comments on the record. It's notable that all the official statements by the Malaysians, the party responsible for communication as per ICAO protocol has been fairly straightforward and consistent, but very very sparse due to lack of information to disseminate.

I have pity on the Malaysian authorities at this point. They don't have anything conclusive to say and various folks inside and outside their government are anonymously leaking left and right. Leakers always have an agenda, usually to get some fact out into the public and sometimes just to inflate their own egos. I wish reporters were more skeptical before repeating what they hear.

Rolls Royce is in an awkward position here. They may have data, but I've got to believe they'd wait on Malaysian Airlines' permission to say anything. Not just to save them embarrassment but also because this lost plane will no doubt end up in a zillion lawsuits. The ACARS system is essential to Rolls' jet engine business; the last thing they want to do is get into conflict with paying customers on who they share ACARS data with. Let's hope the search and rescue teams are privy to relevant information, though.

I'm more than a little curious about what the various military radars know. That part of SE Asia is pretty well armed and watches their airspace and borders. Even with all transmitters turned off, strange aircraft should be identifiable. I feel certain if the plane got anywhere near China's ADIZ it would not go unnoticed, less certain of Vietnam. Again, I hope the search teams at least have access to the relevant data.

Re: deliberate act:
This ABC report quotes a US source saying the two communication signals were shut off at different times, which the source says indicated a deliberate action rather than a single accidental cause:
Two U.S. officials tell ABC News the U.S. believes that the shutdown of two communication systems happened separately on Malaysia Airlines Flight 370. One source said this indicates the plane did not come out of the sky because of a catastrophic failure. The data reporting system, they believe, was shut down at 1:07 a.m. The transponder -- which transmits location and altitude -- shut down at 1:21 a.m. This indicates it may well have been a deliberate act, ABC News aviation consultant John Nance said. U.S. investigators told ABC News that the two modes of communication were "systematically shut down." That means the U.S. team "is convinced that there was manual intervention," a source said, which means it was likely not an accident or catastrophic malfunction that took the plane out of the sky.
Re: decompression:
In this Guardian article, Boeing says this particular plane did not have the satellite transmitter thing that was being mentioned as a possible cause of decompression:
Boeing did state that an airworthiness directive about possible fuselage cracks issued by US authorities in November regarding 777s, which had been linked in some theories to flight MH370, did not apply as the missing plane did not have the specific antenna installed.

Mmm. I'm not sure I buy that 14 minutes apart means human intervention, as opposed to a progressive problem. If they were a minute or two apart, sure, but if you are Bad Person who had taken over the plane and is turning off the various beacons, it seems rather odd to turn off data reporting and then wait around for 14 minutes to turn off the transponder. And I'd really expect them to turn off the transponder first, which is the most obvious and most heavily tracked of the beacons.

Agreed about the progressive problem, tavella. It's weird to me that their expert doesn't see it that way.

And re: the Boeing/Rolls Royce data, from this AP report (via Guardian liveblog):
The official said the Boeing 777-200 wasn’t transmitting data to the satellite, but sending out a signal to establish contact. Boeing offers a satellite service that can receive a stream of data during flight on how the aircraft is functioning. The official, who spoke on condition of anonymity because he wasn’t authorized to speak publicly, said Malaysia Airlines didn’t subscribe to that service, but the system was automatically pinging the satellite anyway. The continuing pings led searchers to believe the plane could have flown more than 1,000 miles beyond its last confirmed sighting on radar, the official said. The plane had enough fuel to fly about four more hours, he said. Messages involving a different data service also were received from the airliner for a short time after the plane's transponder — a device used to identify the plane to radar — went silent, the official said.
So it sounds like, the plane sent the engine-data report twice while it was still in contact. Then ceased to send that data report, but still was pinging the satellite for (several hours?), and that's where the "it was still in the air for several hours afterward" is coming from? And the Malaysians have said they asked Rolls Royce and Boeing, and they said there hadn't been more engine data reports... but maybe RR and B don't have access to the record of the satellite as to who pinged it? Maybe that ping information only became available for whatever reason once the US govt got involved?
posted by LobsterMitten at 4:20 PM on March 13, 2014


Is the fact that ACARS stopped transmitting notable at all? I thought that the system only sent periodic transmissions?

The more notable thing would be if the plane disappeared from radar significantly earlier or later than the transponder stopped transmitting.

The seeming inability to establish a timeline is frustrating.

Here's a new theory.

The idea is that there was slow decompression caused by a non-catastropic crack in the skin of the jet, not noticed by the pilots, who didn't put on oxygen masks and then blacked out from hypoxia.

I mean, I can see why they are thinking human intervention, just because it starts to be hard to figure out a limited sequence of failures that result in first the data reporting system failing, and then the transponder, and the pilots being incapacitated or at least unable to control the plane at all, and yet it is in good enough shape to keep flying for hours. Various subgroups of those, but the whole sequence starts to look weird. But I don't think the 14 minutes is evidence for, and even kinda evidence against.

Though I wonder -- does this pinging system have any location data? And what powers it? I.e., is there any possibility that it was pinging from the wreckage from some standalone power source?

My pet theory is that the newly-found "pings" were actually detected by the NSA -- after all, one of their main purposes is to monitor radio transmissions. They could have recorded the signal from their own satellites or even highly sensitive ground stations. Then the spooks had to do the "parallel construction" thing and come up with a plausible way that civilians could have gotten the same information. That would explain why everyone denied that ACARS data existed right up until today when everyone started confirming it.

Finally, one horrifying possibility: we may never know what happened, since the black box only records the last hour or two before a crash, and there was at least 4 hours between the precipitating event and the crash itself in this case. If there was a struggle in the cockpit, it probably isn't on the cockpit voice recorder anymore; if there was a mechanical failure, the signals leading up to it are probably lost.

Two points from the Guardian's liveblog-
-The transponder will only respond if it's (in-effect) queried by a ground station, so if it were out of range of a ground station it wouldn't be surprising that it was silent. (According to their reporter Warren Murray.)

-NBC reports that US infrared-detecting satellites didn't detect anything (heat signature) that would suggest an explosion around the time the plane lost contact "or in the hours immediately afterward". (That also suggests to me that if the plane was shot down, the US would have detected the missile launch/strike, so, a point against that theory.)

Ugh, no. I've been letting this go for now, but since you keep bringing it up, there's a bunch of reasons why this sounds so great now but doesn't actually have any serious relevance. The biggest issue is that you're comparing an idealized perfect "GPS pinging" device to what has been a complete mess of misinformation and confusion both from the relevant authorities and from news services. Of course the idealized position reporter will look better by comparison. But two points 1) why would that actually behave any better than, say, radar, which requires zero hardware on board the aircraft to work, and 2) why would the information from this device not be similarly corrupted by this mess of a process by which the authorities have been releasing and then de-releasing and then leaking and then denying information about the position reports that do exist. Seriously, there is someone who the newspapers are willing to use as a source who claims the plane flew for hours after loss of contact; how is a "GPS pinger" not going to be embroiled in the same clusterfuck? Between primary radar, secondary radar and ACARS there is already plenty of position reporting for this aircraft, why would this hypothetical device be any more reliable?

BTW there's nothing in the aircraft that cannot be turned off—period. Even the CVR and the FDR have circuit breakers; there is zero hardware that you will be able to certify to fly on a plane that is always-on. So if communication was lost intentionally, same result. Catastrophic electrical failure, same result. Breakup of the airframe, same result. We don't have a damn clue which of these scenarios actually happened, so it's awfully premature to feel vindicated that your hypothetical solution would actually solve a problem when we don't know what that problem is yet.

This situation is overall ridiculous and has nothing to do with a lack of hardware on the plane.

This is completely crazy if some unnamed source has information that the NTSB doesn't, or it's outrageously reprehensible for the news outlets to be reporting this if it's not true.

kiltedtaco,
the WSJ mixed it up, it was not the engine that sent out data. The WSJ published a correction, it says: "The investigators believe the plane flew for a total of up to five hours, according to these people, based on analysis of signals sent by the Boeing 777's satellite-communication link designed to automatically transmit the status of certain onboard systems to the ground." (emphasis mine)
And further: "[...] the link operated in a kind of standby mode and sought to establish contact with a satellite or satellites. These transmissions did not include data, they said, but the periodic contacts indicate to investigators that the plane was still intact and believed to be flying."
And even further: "An earlier version of this article and an accompanying graphic incorrectly said investigators based their suspicions on signals from monitoring systems embedded in the plane's Rolls-Royce PLC engines and described that process."

There are some pings of data - might be just passive - that were picked up by military radars along the coast. Detailed map of radar pings with corresponding flight path. It's confusing and unclear if this are the transmissions WSJ was talking about or some additional contact.

They are splitting hairs -- there were no successful ACARS transmissions, but there were connections to the satellite that is used to send ACARS transmissions. So Boeing, Rolls Royce, and the airline never got a normal ACARS message through on their networks, but the satellite operator can see the "pings."

I don't think the press releases are contradictory, just incomplete.

The satellite operator in this case is Inmarsat but we haven't heard anything directly from them.

The available data on this is totally contradictory, so I think it's way too early to start ruling out scenarios. The ABC report says that (presumably) ACARS was turned off at 1:07L, and the transponder turned off at 1:21L, but every other report has said that radar contact was lost at 1:07L. There's also an ambiguity with turning ACARS off; did it transmit a signal indicating it was being turned off, or are they just reporting the time of the last transmission, after which it could have remained on and just not transmitting. And as I've said before, there is very little confirmation of the satcom reports and many sources denying that anything was received after 1:07L.

why would [a GPS pinger] actually behave any better than, say, radar, which requires zero hardware on board the aircraft to work

A GPS pinger would help in a lot of cases, including maybe this one. ATC radar generally relies on an active transponder on the aircraft responding to pings. Radar works without the transponder, but not nearly as well (no altitude, no plane identity, less accurate position). Radar coverage is also limited to line of sight, which works out to about 100 miles from land in most cases. There's lots of radar holes over water, also low in mountainous terrain. Military radar has better coverage, it's designed to find aircraft that are not looking to be seen, but it's not perfect. Finally, radar is a per-country system, a GPS pinger would be a centralized system whose data goes straight to the air carrier or the public.

You're absolutely right that a GPS pinger could be turned off just like the transponder and voice radios apparently were on MH370. I like the idea of an isolated GPS transmitter that can't be disabled, but it seems very unlikely. Aviation assumes you trust the pilot; no one seriously considers systems for doing something with a plane that's being flown by an untrusted pilot. Which is what makes hijacking so dangerous; there's very little anyone outside the plane can do.

I went researching the AF447 ELT, even scanned the final BEA report, but couldn't find a satisfactory discussion. The ELT apparently didn't work on impact. The report does recommend in future emergencies that the ELT be manually activated by the pilots; I don't think that's been adopted, and it's not clear it's even practical. ELTs are not completely reliable of course, and I imagine they work particularly poorly underwater. Whatever the case, all reports indicate MH370's ELT didn't activate. (ELTs can be disabled from the cockpit, at least in little non-commercial aircraft.)

Today's anonymous reports that the plane was flying navigation fixes is interesting. Flying airways requires a GPS receiver or at least a VOR receiver to find them. If the plane was accurately flying airways that'd make complete electrical failure unlikely. (Even if the pilots had a handheld backup in the cockpit, I can't imagine a pilot choosing that route in an emergency for which they are in control.)

1) Turning off the transponder or any other transmitter is trivial. There are switches to do just that, plus circuit breakers. If the story that the ACARS stopped some minutes after the transponder, that's evidence for human action turning them off.

2) ATC adars work with the transponder. The radar scans, sending a beam of RF energy out. This bounces off the skin of the aircraft and is reflected back to the radar. The radar knows what direction the beam was pointing, and knows how long the beam took to be transmitted, reflected and returned, that gives the radar the distance. This is known as the primary return, and all radars have it.

The transponder* on the plane senses the radar beam and the *transmits* a message. This is picked up by a different antenna on the radar. On the very common ASR-11, the beam energy is picked up by the parabolic antenna, while the transponder's signal is picked up by the flat antenna on top. The primary return, or "skin return" needs the gain and narrow beam width of the parabolic antenna for two reasons. First, because that energy travels twice as far (out and back), it is four times weaker, plus most of the beam energy misses the plane and doesn't come back. Secondly, a wide beam width means the plane is somewhere in that beam, so a narrow beam makes the radar's position report more accurate. The transponder receiver's antenna on the ground has to have a wider beam because it take a tiny fraction of the second for the transponder to actually respond, at long range, the primary beam might not have it in view any longer.

The basic transponder return is a four octal digit code, ranging from 0000 to 7777. Mode C transponders provide the plane pressure altitude, a computer on the ground links the transponder code and pressure reading to a screen, where it then puts the flight number (it knows, say, that AA1186 is on 3471) and the altitude. Mode S transponders provide indicated air speed, plane's rate of altitude change, position, and other details. The ground radar integrates position over time to get ground speed, and altitude over time to see if the plane is climbing or descending, the speed and a climb/descend indication are then added to the standard data block next to the primary return "bilp" on the ATC radar screen. The block looks like this.

AA1886 48
348 ^24
S270N30 H187

This translates to:

HI! I'm American Airlines Flight 1886, and my speed-over-ground is 480 knots
I'm at FL348 (34,800 feet) and I'm climbing at 2400 FPM
I'm set to fly at FLY370, my indicated air speed is 300 knots and I'm flying at 187 degrees.

Turning off the transponder means that the plane's reported altitude and indicated airspeed will disappear. Furthermore, since the transponder's code disappears as well, the ability for the computer to link that blip to that flight number goes away as well. The radar still see the primary skin paint, and can still integrate ground speed. The trace will indicate direction, but altitude information is gone.

All radars have a primary return. You can see airplanes on weather radars, you just can't track them well because the radar turns too slowly. Turning off the transponder doesn't make the skin return go away. Integrating the transponder's info with the primary return is called "secondary surveillance radar," with the secondary data being the transponder's response.

FlightAware and other sites use the Mode S broadcast to get position, altitude, airspeed, heading, etc., but they're not radars -- they're listening for the transponder info and plotting it. They need a radar *somewhere* to scan that plane and trigger the response, but they don't need to be at the radar to hear it, they can then get the position/speed/altitude/heading data from the Mode S data block.

So, when you turn off a transponder, you lose most of the data block on an ATC radar, and anybody tracking via Mode S transponder returns will lose the plane entirely. But the ATC radar still sees the plane.

This is the thing bothering me. When a transponder goes away, an indicator on the blip appears. It's an odd thing to happen. A controller seeing it would be paying attention to that blip. And, if that plane then turned, he would see the plane turn.

Yet, nothing about that came out for days. Another mystery.

Possible flight path plotted according to data from military radars

That's…odd. It's zig-zagging, and yet, it's hitting waypoints?

If it's a hijacker, it's a hijacker who knows how to fly -- that is, not only keep the plane in the air, but use the nav systems to go to a certain point. The chances of hitting four waypoints in the sky by simply flying random turns is astronomical.

A GPS pinger would help in a lot of cases, including maybe this one. ATC radar generally relies on an active transponder on the aircraft responding to pings.

The aircraft also had an ADS-B system that broadcasts it's location on open frequencies and was well within range of receivers, I dont' see what kind of functionality a hypothetical GPS pinger would have over that.

Flying airways requires a GPS receiver or at least a VOR receiver to find them.

No, airplanes have inertial navigation systems, but yes if the plane was indeed flying on an air route, that would indicate someone was in control.

The latest from James Fallows, a reporter who is also a pilot: "explosion now is much less likely; deliberate destruction, by crew or attackers, more so"

I can't disagree. Transponder off, flying all over the sky to waypoints, and then trying to fly to a destination? If the flight track report is true (IF, KIDS, IF, NEVER FORGET THE IF) then the plane clearly flew far beyond the point that the plane when RF quiet, and apparently with purpose.

Who would receive the GPS's reports?

The tragedy has been the disappearance of the plane, but since that moment the problem has entirely been one of communication and coordination between authorities. Years from now it might be revealed that Chinese, Vietnam or Malaysian air authorities had been sitting on data without sharing it, or had been receiving signals from the plane but not logging it, or had deleted their logs.

There should already have been multiple signaling systems that would have reported things but haven't. Another device that should have been sending a signal but didn't wouldn't have helped.

Apparently, it is also possible to switch off the satellite communication. This did not happen at the time the plane vanished from civilian radars. Now, did it switch off after the 4+ hour flight due to the plane powering down or because it was turned off intentionally?

There are several airports in Andaman and Nicobar Islands, only one (IXZ) is open and operated by the Indian Navy. IXZ has a runway of 3,290 m (10,794 ft).
The other airport, CBD, has a runway of 2,717m (8,914ft). Theoretically, both would be long enough for landing a 777, which needs (at max. landing weight) a runway of 8,000ft. The other two airports have shorter runways.

If the signal the military radars picked up was indeed MH370, it's interesting that all of the other countries involved let an unidentified aircraft pass through.

Flying airways requires a GPS receiver or at least a VOR receiver to find them. GPS, VOR, or Inertial guidance, all of which a B777 flying oceanic would have. Indeed, the whole thing would be integrated into a flight management systems. You could even punch in a series of waypoints and then tell the autopilot to fly the plane between them.

The ability to fly without VOR air routes is called "RNAV*" -- instead of flying between beacons, you flight from waypoint to waypoint. To do so, you need to know where the waypoints are, and you need to know, at all times, where *you* are.

RNAV routes aren't uncommon over land**, and are basically the default over ocean. I suppose a B777 could be delivered that wasn't capable of RNAV, but I doubt it's ever happened. Every modern airliners has RNAV on board.


* Originally "Random Navigation", but now, it's called "Area navigation."

** Many of the northern Transcon routes in the US are RNAV, because of the mountains in the west and the Great Lakes, beacon airways are thin. Being able to scoot across the lakes off the beacons makes it much easier to avoid weather.

This is the part that I don't get. Regardless of all the transponders/signal doohickys on the plane itself, it's pretty nerve wracking to think a huge plane can fly for any period of time on/over/or even near a landmass without someone tracking it and asking questions.

Yes, pedants, an inertial navigation system would work for that waypoint navigation in addition to GPS or VOR. INS is an electrical system too. My point is if that plane flew those airways, then the electronic navigation equipment was most likely working. Also goes without saying, that's not a route you voluntarily fly. If that route report is accurate, some sort of hijacking seems much more likely.

BTW, this version of the map (from this blog) is the best I've seen in that it's drawn on top of an aviation map with the intersections marked. Here's a map I plotted of the route on Skyvector's charts; the high airways view shows the intersections. I'm refraining from speculating on these routes because I don't really understand high airways or international routing. One thing I'd love to know is if the plane actually hit those points or just got kind of near them; that makes all the difference.

I suspect that since the radar data has not been released to the public and the original news article simply included waypoints with which the radar contact lined up with, those maps are actually made by linking those waypoints on the map and that's why they match, instead of the tracked contact matching the waypoints exactly.

Or does the new information (if accurate!) really strongly deliberate and conscious flight westwards towards waypoints, and human rather than mechanical means?

Well, if you are looking on your radar logs for an airplane, and there is some probability you will interpret a blip from another airplane as the one you want, then most of your false positives are going to be on heavily used routes. These people are under a lot of pressure to find any blips that might be the right plane but they may just be looking at other planes with no transponder data. So I wouldn't necessarily believe the waypoint stuff.
posted by miyabo at 10:08 AM on March 14, 2014


The possibility that the plane was flown by waypoints for several hours is interesting given that contact was lost at a waypoint. If true (and it may well just be an artefact of how the information was released) it would be highly suggestive. Were this kind of navigation intended from the start then this would not be a coincidence, and whoever turned off communication and made the change of course must have been somehow in control some deal of time before the waypoint.

Having sat in the cockpit of an aircraft in flight for several hours, I learned that there are literally roads in the sky and intersections where these airways meet. So you fly to one, then turn up another airway and then fly to another. Its not really zig-zagging, its going from one intersection to the other. Air traffic control usually routes you on which airway, which altitude and which waypoint you are headed for.

This could mean they wanted to appear like a random flight to air defense radars.

It would have been very wrong. It would be obvious what to go for -- WMKN, Sultan Mahmud airport at Kuala Terengganu, which has an 11,400' runway pointing in from the ocean, so you don't even have to worry about minimum safe altitude. If that was too far, the 6800 foot runway at WMKC, Sultan Ismail Petra Airport at Kota Bharu, would be closest that they could confidently land on, but Narathiwat wouldn't be much farther and have 7000' of runway to work with.

It would be very unusual to program waypoints in a diversion situation. You'd punch up an airport and hit "direct." If (again, IF) they flew those waypoints, it's because they didn't want to land in Malaysia or Thailand. And since those aren't VOR intersections, the only way you could fly them is with RNAV.

Well, if you are looking on your radar logs for an airplane, and there is some probability you will interpret a blip from another airplane as the one you want, then most of your false positives are going to be on heavily used routes

Except look at the high altitude chart. That line of waypoints isn't on a route, it's crossing lots of routes. It's only at the end that it looks like it's trying to head at least somewhat in the general direction of the traffic, roughly along the P628 airway.

Indeed, it sort of looks like they were trying (or trying to make) people think that first, they were going for Banda Aceh in Jarkarta, then they turn towards Phuket in Thailand, then towards Port Blair (VOPB).

If that's the case and they were trying to steal the airplane, I would take a look at Car Nicobar AFB (VOCX). If they drop low at IGRX, they might drop off Jarkart/Thailand/Malaysia radar, then a turn to the left and make for Car Nicobar. Issue: It's a military airport, an Indian Air Force base.

Thinking about it a little more, I don't think that it is quite right that whoever made the course change must have been in control for some time before the communications were turned off. The turning off and reaching the waypoint were several minutes apart, not at the exact same time. However, if the person making the course change meant to navigate by waypoints then it is a coincidence that they took over just before the plane was to hit one on its route.

But also, Thing, didn't the turning off of the transponder and the shift westwards occur not only near a waypoint but also between the Malaysian and Vietnamese (?) air traffic control boundaries - right after the pilot had said goodbye to the Malaysian one and before entering the Vietnamese airspace? In other words, it seems that it would be a natural place to disappear if one wanted to disappear and were well-versed in commercial flying?

Yes, it would mean that if the plane was not hijacked by its pilots then whoever did hijack it had some existing knowledge of flying and technical details of the flight. The timing was not random but coincided with the steps that would need to be taken for the following part of the flight. Unless they "lucked out" the hijackers knew when to make a move.

Of course, this all still assumes some kind of hijacking, which might not be the case.

I would have thought a stolen airliner would be essentially unsaleable, much like a stolen van Gogh--except that a reclusive billionaire couldn't keep it in his basement.

Like I mentioned earlier, I think there are a lot of better ways to get a 777 cheaply than stealing it...especially as you don't really want 240 murder counts on your head(s) if/when they catch you. And if you don't plan on killing the hostages, you don't want to babysit 240 people, either.

There is no stolen scenario which doesn't make more sense to accomplish another way. Even if you don't purchase the rotting remains of a bankrupt airline, you could start a new one (cargo, preferably), lease a 777, send it off for "paint" or whatever, and never make a payment. Big business has shown that you need to invest very little of your own money to make this happen. Hell, make some podunk town your airline's new home base and you can probably get the local council to kick in the money to start it.

You can, in true spy-thriller fashion, then decide that they thieves really wanted a person or persons on-board, or an item the plane was carrying. Again, this is the riskiest way to accomplish that goal, perhaps with the exception of kidnapping a large group of people--maybe someone needed a team of calligraphers? An item so valuable that it was under intense security to the point this was the easiest way to get it would not have been on a flight like this.

Which isn't to say none of this is possible, it's just really unlikely.

Yes, but that's assuming you land right at the landing end. Any drift down the runway before touchdown and you go long.

Looking at a sat image of that runway, I'd be loathe to try. It's narrow, short, and there's nowhere to really run off the runway. You either stick it or you die. The only reason you'd even try is if the only other option is "or die."

I agree with maxwelton in that there are many compelling counter-arguments to the theft scenario. And yet, here we are.

Since we're already through the looking glass, here are some more possibilities:

1. The DB Cooper Scenario: The hijackers never had any intention of setting the plane down. They flew over the Andaman Islands at low altitude, bail out, and leave the plane and passengers to fly on to their doom deep in the Indian Ocean and distracting the search parties long enough to make a clean getaway. Why would someone do this? A) Simple terrorism. As we have seen, the vanishing airplane is good publicity, and terrorism is essentially a PR stunt. B) Kidnapping a specific individual. Good luck keeping track of him/her after you push them out the back door over a jungle at 3 AM. C) Stealing high value object. The valuable object would have to be in the cabin and not in the cargo hold, which seems unlikely. All told, chances of success also seem pretty freaking low. You'd have to smuggle one or more parachutes onboard the plane for starters.

2. Mass Kidnapping Scenario: The kidnappers have already contacted the authorities with ransom demands. The authorities are keeping it secret, which might explain some of the confusion and contradictory information we've been hearing. Why would the authorities keep it a secret? What other signs would we look for if this scenario is actually happening?

3. Massive Terrorist Screwup: Other scenarios depend on competent and well-prepared terrorists. Maybe they had something else in mind, lost control of the plane, and it flew off into oblivion.

I would have thought a stolen airliner would be essentially unsaleable, much like a stolen van Gogh--except that a reclusive billionaire couldn't keep it in his basement.

Well, as long as we're on the subject of theft: Would someone (maybe a company or country) be interested in stealing the plane to reverse engineer the technology for their own aviation program?

But, you'd still be reliant on a foreign manufacturer. Not only for parts, but probably for servicing, maintenance, and expertise.

And, if I buy a car, I can take it a part and do whatever I want with it. If someone bought a Boeing, do they have the same ability to take it a part and do whatever with it? Doesn't it come with certain obligations and legal promises not to do that sort of thing?

Also, the large airline industry is basically a duopoly between Boeing and Airbus. They sold $423 billion worth of jets last year. I'm sure there's a lot of non-American and non-European manufacturers that want to compete.

Eh, everyone has a crazy theory. This one's mine.

It's hard to see what the purpose could have been, though. The only obvious target in that direction with a history of high profile terrorism is India, and why would you hijack a plane in Malaysia for that? For that amount of effort, you could hijack one a lot closer, and thus have a full load of fuel. Planes aren't actually great weapons when mostly empty. If the plane itself was the target, for hostages, terrorists generally would announce that so as to, y'know, provide terror. If someone just wanted to steal a plane you can rent one a lot cheaper, and it's hard to imagine there is any person or item on board sufficiently valuable to justify non-ideological theft.

Alternate theory #3134 (aka 'Grand Unified Theory'): Plane is hijacked and taken off course to destination/purpose unknown. Unrelated, a lithium battery explodes in cargo rupturing the air frame, causing a slow decompression that incapacitates hijackers before their plan is complete.

Sharp Changes in Altitude and Course After Jet Lost Contact
Investigators have also examined data transmitted from the plane’s Rolls-Royce engines that shows it descending 40,000 feet in the space of a minute, according to a senior American official briefed on the investigation. But investigators do not believe the readings are accurate because the aircraft would likely haven taken longer to fall such a distance.

“A lot of stock cannot be put in the altitude data” sent from the engines, one official said. “A lot of this doesn’t make sense.”

For reference, falling 40,000 feet in under a minute is a minimum speed of about 450 mph, which would be consistent with a pilot suicide intentional dive or a United 93 scenario. It's not like it doesn't make sense because it's faster than a 777 can fly.

Yeah, a plane would take much longer than a minute to fall 40,000 feet. The question is how long a deliberate powered dive from 40,000 feet would take. That's just under 700 feet a second. Which is rather a lot but I have no idea if its too much for a powered dive or not.

I think a falling engine without any drag or lift from wings would take about 50 seconds to fall 40,000 feet. I doubt the terminal velocity of a tumbling engine would take off too much from that time. I don't know what it would take for an engine to fall off, but didn't one fall off the plane that crashed in Queens in 2001? I would think a powered dive is more likely, but it sounds like investigators have ruled that out based on their data.

I predict that the accident will turn out to be due to pilot error (not following standard procedures or failing to properly notice/respond to the situation) combined with a mechanical or systems failure caused by a manufacturing defect, improper maintenance, or substandard repairs.

I don't see any need to jump straight to OMG TERRORISM or crazy Tom Clancy plots until the black boxes are found and investigators rule out the above based on their data analysis. This effort takes much longer than a news cycle to play out, so we'll just have to be patient.

NYT update: "Sharp Changes in Altitude and Course After Jet Lost Contact"

... Because the plane stopped transmitting its position about 40 minutes after takeoff, military radar recorded only an unidentified blip moving through Malaysian airspace. Certain weather conditions, and even flocks of birds, can occasionally cause radar blips that may be mistaken for aircraft, and the Malaysian authorities say they are still studying the signals to determine if they came from Flight 370.

But the person who examined the data said it leaves little doubt that the airliner flew near or through the southern tip of Thailand, then back across Peninsular Malaysia, near the city of Penang, and out over the sea again. That’s in part because the data is based on signals recorded by two radar stations, one at Butterworth air force base on the peninsula’s west coast, near Penang, and the other at Kota Bharu, on the northeast coast. Two radars tracking a contact can significantly increase the reliability of the readings.

I have no idea how plausible this is but linking it anyway -- a DC area local news station is reporting that Boeing had previously warned the FAA about the possibility that a 777's computer systems might be vulnerable to attack, and also reporting on the demonstration of an exploit (using an Android phone to take control of some plane electronics) at a hacking conference last year - which we discussed here.

I don't see any need to jump straight to OMG TERRORISM

I don't have any idea what caused the plane to disappear but at this point I'm not sure it's fair to characterize speculation as jumping straight to OMG TERRORISM. There are lots of weird things that don't add up and which make the most common causes of plane crashes (which is what you predict) less likely.
posted by Justinian at 4:24 PM on March 14, 2014 [1 favorite]


For example, accounting for some of the "facts" (and I use that term loosely at this point) we think we know requires slow decompression which renders everyone unconscious. However, in such a case you would expect the plane to keep flying straight. But the latest info is that the plane flew in a pattern between waypoints after the transponders went offline. Which requires a conscious pilot. And rapid decompression or a catastrophic failure at altitude makes a plane flying that sort of pattern even less likely. The plane would crash relatively quickly.

Right now we're looking for an explanation which accounts for:

1) Various sources of information as to the plane's location, speed, altitude, etc going offline or being shut down at significantly different times.
2) No contact from anyone on the plane. Not from the pilots nor from anyone on a cellphone.
3) The plane keeps flying for hours after contact was lost.
4) The plane doesn't fly straight, it flies in a pattern indicative of either a conscious person at the controls or a pre-programmed autopiloted path that does not correspond to either the initial flight plan or a flight plan you would use in case of emergency. The plane should not have been flying in this direction under any circumstances.

Sure any of those 4 points could turn out to be based on erroneous information but as far as I can tell it's the best we have right now.
posted by Justinian at 4:34 PM on March 14, 2014


Oh! And the precipitating event takes place in exactly that very short window of time after the pilot has confirmed exiting Malaysian airspace but before the pilot has confirmed entering Vietnamese airspace. Obviously that's not evidence but it is a pretty terrible coincidence if a catastrophic event occurred then since it is the worst possible moment.

It's straightforward to rationalize almost any of the information taken by itself, it's when it all gets put together that it becomes more difficult.

No contact from anyone on the plane indicates to me that either there was a catastrophic mechanical failure, a slow decompression, or that the plane was hijacked. Are there other explanations?

And it's tough to explain away the flight path of the plane if there was either a mechanical failure or a slow decompression.

Even when I've landed (anywhere in the world, including Malaysia) and the plane's taxi'ed into the airport I still have to wait a while before the phone picks up any sort of signal.

To me, the new stuff reported in the NYT article suggests the Terrorist Screw Up Scenario: Plane takes off and climbs to altitude. Hijackers take over the plane, incapacitate the pilots, and turn off the transponders. Then, thinking they are no longer being tracked, they turn back towards Malaysia. Maybe the plan is to fly back to Kuala Lampur and crash the plane into the Petronas Towers, or maybe the target is in Penang. Either way, something happens en route. Maybe the passengers revolt, kill the hijackers, and realize there's no one left to fly the plane. Maybe they're not as good pilots as the 9/11 terrorists were. Maybe they just get lost flying at night over water. Maybe they depressurize the cabin and climb to 44,000 feet to kill the passengers, as the pilot in the Times article suggests, and accidentally deprive themselves of oxygen, too.

I've read that a plane with no radio communications can fly in a triangular pattern to signal distress; would that account for all the turns? (though, I think it's not meant for big airliner jets). The Tango thing might be part of a longer message, as Tango is the code/phonetic word for 'T'. If it was hijacked, there seems to be no attempt by the hijackers at making any kind of statement before the plane went down, except maybe these communications. (on preview, I see it's the Malaysian Airline distress signal).

I find this whole episode to be incredibly humbling. First, the ocean is so very large, and we are pretty small - even our massive aircraft carriers and navy vessels are still searching. And, second, while airline travel is routinized and dehumanized to a rather high degree, it's still a rather tenuous thing. All of the training and engineering and physics and nature have to come together for the plane to have a safe flight, but if you fuck up one tiny part of any of these, whether on purpose or not, it's all over. I feel so terrible and irrationally helpless for all the affected families that the world, for all that it's accomplished in science and military prowess, hasn't been able to find this plane yet.

No, a plane on an instrument flight plan (as here and essentially all airliner flights) has specific procedures for lost communications. If it's something more urgent they're not going to putz around flying in triangles; they're going to find a place to put the plane down as safely and expediently as the situation allows.

Malaysia Airlines Flight 370 Probe Sharpens Focus on Sabotage

"Officials suspect two different systems were shut off after the plane took off last weekend, one shortly after the other, people familiar with the investigation said. About an hour into the flight, the plane's transponders stopped functioning, making it much more difficult for air-traffic control personnel to track or identify it via radar.

In the ensuing minutes, a second system sent a routine aircraft-monitoring message to a satellite indicating that someone made a manual change in the plane's direction, veering sharply to the west. . .

[A]s details emerge an accident appears increasingly unlikely. The first loss of the jet's transponder, which communicates the jet's position, speed and call sign to air traffic control radar, would require disabling a circuit breaker above and behind an overhead panel. Pilots rarely, if ever, need to access the circuit breakers, which are reserved for maintenance personnel.

A physical disconnection of the satellite communications system would require extremely detailed knowledge of the aircraft, its internal structure and its systems."

Wiki article on Bayesian search theory. The important thing is that you incorporate both the likelihood of the plane going down at a particular spot, and the probability that you would actually find it if it did so -- for example there is no point in searching in a rainy area if you could search 100x faster in a sunny area. The whole process is automated by well-tested software so it is likely the search teams are using it now.

There are reports in the last few minutes from a Reputable International News Organization that "The plane could have flown 1,000km off the coast of Perth, Western Australia."

Okay, fine, cool, but here is a thing that's going on; media organisations are grabbing unsourced drips of information or vague theories from some "expert" who they talked to and posting it instantly online because, in doing so, they instantly get 800,000 clicks on the article.

CBS: Malaysian investigators conclude flight hijacked

Also I did listen to the Alex Jones show in its entirety. Link here. It was a pretty brutal four hours but it's OK if you only do it a couple times a year.

1. Jones speculates that some earthbound rogue hackers took control of the plane from the ground and steered it where they willed. Claims sources that the airplane's (and all commercial jets') computers are vulnerable to this type of attack from NSA or CIA or Chinese or Russian or Iranian or your own clever teenager's counterparts.

2. the McAfee interview starting at around 2:09:50 is compelling and was almost worth suffering through the first two hours to get to but you all can just skip that crap! McAfee's hair and beard are stunning so you can just take a peek for that much. He is far more lucid than in his other recent interviews. They have video of McAfee shooting a .50 caliber anti-armored gun hand held. He is like a most interesting man in the world character. He has a new smart phone app, cognizant, which purports to show you just what permissions you are giving to facebook, twitter, google, &c on your phone.

The last two paragraphs of the above WSJ link -- Malaysia Airlines Flight 370 Probe Sharpens Focus on Sabotage have been edited from:

If a criminal probe is launched, the FBI is likely to send in a phalanx of agents and other personnel. Such a probe is likely to involve many countries but aviation experts believe it would be headed by Malaysia because of the aircraft's nationality.

One U.S. official said Friday that pursuing an international criminal investigation would be "a huge challenge" because so many governments will have an interest in the process and outcome. So far, U.S. officials have not found derogatory information on the pilots or anyone else on the flight manifest, the official said.


to now read:

If a criminal probe is launched, the FBI is likely to send in a phalanx of agents and other personnel. Such a probe is likely to involve many countries, but aviation experts believe it would be headed by Malaysia because of the aircraft's nationality.

"The FBI would have full entrée into the case because of the American citizens on board," said Robert MacIntosh, who previously headed up international relations for the NTSB.

So far, U.S. officials haven't found derogatory information on the pilots or anyone else on the flight manifest, the official said.

Some U.S. aviation experts question how smoothly any complex criminal investigation would proceed. Already, Mr. MacIntosh said, "certainly there has been competition between [Malaysian] civilian and military officials."

As the demand for answers heats up, Mr. Healing asked: "Are they prepared to deal with this kind of massive international investigation?

however i want to criticise the general trajectory of the governance (and have!), the govt has always been committed in staying neutral diplomatically and maintaining relations with everyone (even Zimbabwe; though they were at the forefront at the anti-apartheid sanctions against pre-ANC South Africa), although now it's being confounded by all the latent fundamentalism and xenophobia that the domestic politicians are fostering. So even though at the highest levels they've remained pragmatic, the toxicity has pretty much affected the quality of their next gen of govt officials and diplomats.

Oh, I'm not sure why the talking heads on the TV say that without a claim of responsibility this is unlikely to be terrorism. Hell, the only claims of responsibility for the most spectacular act of terrorism in modern times (9/11) were false and retracted within hours.

1. Transponder manually shut off before the Malaysian east coast border.

from my fb feed:
My rough transcript of the useful part of Najib's update on MH370:

"...[W]e can say with a high degree of certainty that the aircraft communications, addressing and reporting system was disabled just before the aircraft reached the East Coast of Peninsular Msia. Shortly after, near the border of Msia and Vietnam air traffic control the transponder was switched off. Royal Air Force showed an aircraft did indeed turn back, flew in a westerly direction over Pen Msia then turned northwest.

"..These movements are consistent with deliberate action by someone on the plane. Today, based on raw satellite data...we can confirm that the aircraft shown in the primary data is MH370. FAA, NTSB, AAIB, and Malaysian authorities, working separately on the same data, concur. Last communication between plane and satellite at 8.11am on Saturday, 8th March.

"The team is making calculations where the aircraft may have flown after the last point of contact. Due to satellite data, unable to confirm the last location of plane. Based on this new data, the aviation authorities of Msia have determined that the last communication was in either 1) northern corridor stretching from Kazakhstan, Turkmenistan to Thailand; 2) indonesia to southern indian ocean. Turning back to examining crew and passangers. Despite media reports that plane was hijacked we are still investigating all possibilities. Stopping search in South China Sea."

Feel scarier to me too. But I'm telling myself that's because of the times. 20, 30 years ago hijackings happened all the time. Now they're rare as hen's teeth. But probability says they're never impossible.

Holy shit, if there was satellite ping on the plane at 8:11am that's more than enough time to have headed over the Indian Ocean and crossed India to Pakistan and points northwest. How can a plane do that without being intercepted by the air force?

It's got to have gone down in the ocean? Except then you have to explain what it was doing over the ocean for 7 hours. Circling? Why?

Either it was flying in circles until the fuel ran out or it flew over land and nobody bothered to check it ou. I don't know which is worse.

I could swear I'd read that it had 4 hrs left after "last contact" (the inital last contact, which started off the search).
posted by five fresh fish at 11:53 PM on March 14, 2014


7 hours of fuel is enough to get to Kazakhstan. 4 hours would get to India but no farther.

But again I can't imagine India wouldn't see a plane of this size over its airspace. It must have turned south and crashed into the ocean after running out of fuel. But that doesn't make any sense.
posted by Justinian at 11:57 PM on March 14, 2014


Does the satellite contact at 8:11a necessarily mean that the plane was still flying/operational, or is this something with a battery backup that could keep going after a crash/fuel loss?

I don't really buy this new direction, and it sounds like an incompetent bunch of government officials are trying to get rid of this hot potato as fast as possible so that someone else can be blamed. "Not our fault it slipped airspace and wasn't picked up by multiple radars -- go ask India or Kazakhstan some difficult questions, instead!"

So, several hours ago Nelson highlighted this quote from a WSJ story:

"In assembling the chain of events, investigators are trying to determine why the jet didn't travel farther from its takeoff point given the number of hours it apparently was in the air." [my emphasis]

Which I thought might be someone misspeaking -- because at this point, we don't know how far it travelled, do we?

Then I thought, ok, the US unnamed sources have seemed pretty univocal that they have some reason to believe (a) the plane crashed (b) into the Indian Ocean. If the US has some other source of info they are not releasing (some imaging or radar or something from a spy plane or sub or who knows that) that leads them to think firmly that they know broadly where the plane went down, that would make sense of the above quote.

The 7 hours thing fits with that... if they flew for 7 hrs, that means they could have made landfall in more places if they wanted, so maybe it makes less sense to fly over ocean until you just run out of fuel.

But the "we aren't sure which of two tracks it took" stuff is puzzling -- suggests the US info is not so clear on (a) and (b) as it had sounded like.
posted by LobsterMitten at 12:18 AM on March 15, 2014


It's happened otherwise before. From what I've seen online regarding the pilot, he seems to be a stand-up guy - an obsessive aviator, spending his spare time building cool flight-sim PCs. Of course, that's just an impression, and anyone can broadcast an impression. That's basically what social media is for. I don't know as much about the First Officer. But the tabloid of photos of the two guys chilling with chicks, I would think, would defeat any ideas of Nasty Angry Islamic Jihadists. Suicide, obviously, is always on the table. The Malaysian PM's comment, however, seem to suggest that they are doubling down on this line of enquiry.
posted by Jimbob at 12:19 AM on March 15, 2014


I first learned about the flight having gone missing last Friday afternoon (central time - 14 hours behind MYT before last weekend's DST), which would have been pretty close to the initial announcement from MA that they had lost contact with MH370 several hours earlier. It's kind of horrifying to me to think that the plane was potentially still in the air and flying at that time.
posted by triggerfinger at 12:22 AM on March 15, 2014 [3 favorites]


Here's a timeline of known events of the flight. It's a few hours old so doesn't include press conference info. I think all times are Malaysian times (i.e. the last communication at 1:07 am was in the same time zone as the last radar ping at 8:11 am).
posted by triggerfinger at 12:32 AM on March 15, 2014


Suicide, obviously, is always on the table.

But if it is suicide, then it would have been easier just to crash into the Gulf of Thailand anytime during it's regular flight path. Also, if the pilot or first officer wanted to commit mass murder and suicide, there were a lot of big cities along the coastline to crash into. But, they didn't do that either.

Instead, they flew west. Which makes no sense. What's out there?

I mean, if the Sept 11 terrorists used box-cutters, why not a broken bottle? All the time I see the carry-on bag allowance waived if you are holding armfuls of shopping bags from the duty-free shops.

From WSJ streaming:
Australia is waiting for a request from Malaysia before investigating a report that Malaysia Airlines Flight 370 may have sent a satellite transmission signal from over the southern Indian Ocean...

...a spokesman for Australian Defence Minister David Johnston said. “We have contacted the Malaysians to tell them we are aware of the reports. But it is a Malaysia-led operation and it’s up to them if they think it’s something they want us to look into.”

Australian security and defense experts expressed surprise that a civilian aircraft could have traveled so close to Australian territorial waters without being observed, as the country operates one of the region’s most sophisticated and powerful surveillance radar networks.

The Jindalee Operational Radar Network (JORN) can scan over the horizon across Australia’s north and west... tracking all sea and air movements over a distance of 1,000 to 3,000 kilometers, depending on weather conditions. That would likely have meant the the Boeing 777-200 would have been spotted and tracked, even with its identifying signal devices switched off.
Waiting for a request? What does that mean? Can't Australia looks at its own radar signals?

Harsh words from the Chinese:
Malaysian Prime Minister Najib Razak revealed a trove of new information that virtually made the massive rummage in South China Sea for the Boeing 777 aircraft and the 239 people on board a huge waste of valuable time and resources....

Given today's technology, the delay smacks of either dereliction of duty or reluctance to share information in a full and timely manner. That would be intolerable.

As the leader of the international search and rescue mission, Malaysia bears inescapable responsibility. Other parties that possess valuable data and information, including plane maker Boeing, engine manufacturer Rolls-Royce and intelligence superpower the United States, should also have done a better job...

it is vital and imperative that the Malaysian side work more thoroughly and efficiently and other major information holders -- not least the Unites States -- be more open and forthcoming.

I have to agree with the Chinese response on this one.

Yeah, China probably has a few cards that they're holding close to their chest, but all their past sins in this regard doesn't excuse Malaysia for wasting so much time, money and effort for a search that they knew to be pointless.

There is a lot of information that should have been shared sooner. Not really sure what the manufacturers should be sharing that they aren't already, but it would be very interesting and useful to know if the US have any information on the possible hijackers. They have a boarding list, after all.

There's no indication that anyone was sitting on the satellite data for more than a day or so, which is probably the bare minimum time needed to confirm that it was valid, so the Chinese venting is pretty unfounded. It also sounds like Inmarsat might have discovered this data on their own after the search wasn't turning up anything, and it seems like such an edge case that it might be understandable that the Malaysian investigators didn't know about it.

What makes you think that they knew it to be pointless. Both the radar data and the satellite pings were very tentative and even so, they actually widened the search area considerably after the radar data was available. This is the first time that an aircraft has been tracked using satellite data like that.

I'm strongly inclined to think that whoever turned off the communications systems also turned off the cockpit voice recorder and flight data recorder. Without data from those it will be very hard to know what happened. We might never know.

posted by YAMWAK at 7:52 AM on March 15, 2014


Last known contact was at 8:11am. The satellite handshakes hourly, so there is a possibility the aircraft flew for some time longer than that. The airline should know the exact fuel load, which puts a cap on flight time/distance, provided it was not refueled.
Here is a picture of the satellite position and where the aircraft could have been at the time of last handshake.
In the absence of raw radar data from the other countries, investigators can draw conclusions that a crash could be more likely because the duration of the flight corresponds with fuel load. If non-malaysian military radars picked up on MH370, that changes things. It might already have, according to this tweet by a BBC correspondent.

If your goal is to hijack a plane and take it somewhere why mess around? OTOH if the plane has some unusual mechanical problem or if the crew is incapacitated, all sorts of weirdness is possible.

The map pjenks linked to is very interesting but it does make the assumption that the plane was flying in something close to a straight line the entire time -- not circling for a period, doubling back, or (if we're going there) sitting still on the ground. So the map is just another educated guess.
posted by miyabo at 10:19 AM on March 15, 2014


True, though at least the last ping received from the plane put it somewhere in the blue-shaded region regardless of its path... which raises the quesiton, if all the satellite pings are of this form - i.e., they just give us a ring-shaped region that it was in - can we build a picture of its prior path and figure out if it had been circling/zig-zagging?

I gather they haven't released the intermediate ping locations, so maybe *we* can't, but I imagine the investigators are doing this.

I'm not sure if things have changed, but early on the Chinese government supposedly put a leash on the local media about this:
Central Propaganda Department: The media may not independently analyze or comment on the lost Malaysia Airlines flight. Related coverage must strictly accord with authoritative information issued by the Civil Aviation Administration of China and with Xinhua News Agency wire copy. The domestic aviation department can promptly provide related information to passengers’ family members. All media must refrain from interviewing family members without permission, and must not incite any discontented sentiment. All media continue to give increased publicity to the Two Sessions.
For obvious reasons, we're not going to find an official memo about this, so it's difficult to verify it.

It's been said elsewhere, but the US probably has very good radar coverage of Central Asia thanks to the bases in Afghanistan and nearby warships.

Re: Maps
My understanding is that a satellite does not give an exact position, hence the two corridors. Satellites tend to have more than one antenna, pointed in different directions, and make no distinction between the received information.
What the investigators did was to compare data from different satellites for overlap, they could exclude areas covered by other satellites, thus knew which satellite the last ping(s) had to come from.
The last assumed contact point on military radar was (Pulau Perak) at 2:15. After that the aircraft left Malaysian airspace.

Now, if one could establish which satellite recorded the handshakes from MH370, it would be possible to draw corridors for every ping between 2:15 and 8:11 am, or possibly from 1:22 am on - when the last proper contact was. Then a route could be traced.

But since the aircraft could have flown for a while longer than 8:11 (hourly handshakes), they are probably working on calculations for a probable further route, to refine the search and find the plane.

posted by rosswald at 11:14 AM on March 15, 2014


Neither of the corridors make any sense. The northern corridor requires the plane to fly over airspace in which is should have been constantly detected by radar. The southern corridor means the pilot was deliberately just flying around until he ran out of fuel and crashed. But in that case why not dive straight into the water much earlier in the flight?

But the "we aren't sure which of two tracks it took" stuff is puzzling -- suggests the US info is not so clear on (a) and (b) as it had sounded like.

The only tracking info they have from the satellite is signal round trip time, which gives you distance from the satellite. You plot that circle.

You now erase the part around Malaysia, which was under radar coverage, then you have two "tracks" -- the arc that's north of Malaysia, and the arc that was south. You then plot fuel ranges, and cut out the parts beyond max range. This gives you basically two patches where the plane could have been when that one satellite got that ping.

If they went north, between China, India, and the US in Afghanistan, they were tracked by radar -- both countries have extensive air defense networks, and we have significant presence in Afghanistan. If they went south, they were over the Southern Indian Ocean, near the Kergulan Islands, which don't have an airport. The entire area is basically ocean. If they were over that spot, they crashed into the ocean.

If they flew low to get under the radar, they would have to get much closer to those countries to be seen -- but flying low means you're both burning more fuel *and* your going slower. If they did fly low, they're not nearly as far out as they could have been if they'd flown at high altitude.

As far as I understand, data from just one satellite was used. Inmarsat IOR marked in blue here. It is parked in geostationary orbit over the equator at 64 Degrees East and what they did was work out how long the ping took to travel to the satellite. Thus the possible paths lying around a circle centered on that point.

I guess the working theory is that they wanted the plane to disappear completely. If it were a suicide it's even possible that they were already dead by deliberate depressurization and the autopilot was left to run the plane through a pre-programmed route. It would have been possible to disable the comms, program the route and initiate depressurization before the passengers were likely to notice anything wrong.

And this is of course complete speculation.

In absence of a map of location fixes, I'll take a simple list. Time, position, altitude. The reporting I've read is conflicted about what we know. Last night's WSJ article says "the plane kept broadcasting its location hourly via a satellite communication system for five more hours". That suggests a fairly regular set of positions for the plane independent of radar. I haven't seen those positions reported anywhere, just the last ring around the satellite.

Another WSJ article suggests most of the Inmarsat fixes include precise data: "the transmissions included detailed information about the plane's location, speed and bearing." IIRC the last position from Inmarsat data is only that vague ring because it's not a complete message. Ie: just detecting some sort of signal, and not the data in the message.

The usefulness of this Inmarsat data makes me once again reiterate my position that satellite uplinks of GPS position would be enormously useful in a case like this. Although if there's a determined attacker in the cockpit shutting off reporting, that GPS pinger could be shut off too. I wonder if the data got to Inmarsat only because some hypothetical attacker didn't know about the engine reporting system? Or it's self-contained and they weren't able to disable it?
posted by Nelson at 11:53 AM on March 15, 2014


So there's two possibilities, I guess. One, a strange and elaborate suicide by one of the pilots. It'd almost have to be one of the pilots, given the skill shown. In which case it probably flew off into the South Indian ocean and crashed when it ran out of fuel. But that seems really bizarre; you can certainly believe in the suicidal impulse where a depressed pilot dives his plane into the ocean, and it's even thought there may have been a case of it with Egypt Air 990. But that's a hell of a lot different than flying for *7* hours just to kill yourself, and if they merely wanted never to be found, flying back across Malaysia to ditch in the Indian Ocean would have likely done it.

Second, it's somewhere in the northern arc and was a hijacking. In which case, you have to ask _why the hell Malaysia_? If you wanted to hijack a plane to somewhere in central Asia, there's plenty of places far closer. So it seems like either there was some reason it was an easier target, i.e. they had suborned a crew member, or there was something or someone on that plane that they really wanted. The latter of which sounds truly ridiculous and movie-plot like, but the whole thing is just strange.

Either way, it seems like the passengers must be dead. Even if it landed rather than crashed in the northern arc, it seems near-certain that if the passengers were conscious for any significant amount of time that some text messages wouldn't have been sent, and even if they were later incapacitated they'd be sent if a cell tower came within range. Especially if a plane was flying low to evade radar. And I can't imagine hijackers keeping good enough control of 200+ people that they could collect all the phones and disable them, not post 9/11.

The suicide scenario reminds me in some ways of the Fedex 705 incident. In that case, a Fedex pilot who was not piloting the plane tried to kill the pilots and crash the plane so his family would get his life insurance. Not that that is specifically what happened here, it is just an example of a surprisingly elaborate and premeditated scheme for someone to kill himself using an airplane.

No. Only if the cabin lost pressure. The plane's not rated to 45,000' but that probably has more to do with aerodynamic performance than cabin integrity. Of course if an adversary in the cockpit wants to kill the passengers then they could deliberately disable pressurization, but again we're guessing.

It's funny how we keep looking for some rational explanation. Maybe the pilot went crazy. Maybe there's a crazy hijacker. Maybe something failed and a hypoxic pilot started acting irrationally. Maybe there's an unpredictable mechanical failure and the plane itself is behaving crazy. The truth doesn't have to make logical sense.

Worth mentioning that the 45000 ft estimate came from radar at a point where the plane was 150-200 miles from each of the radars - and at least based on one piece I read, altitude estimates from radar at that distance are quite unreliable*. When the plane was closer to the radars (i.e flying over the peninsular) the altitude was estimated at a more sane 30000 ft. So it's possible the "climb to 45000 ft" is simply a mirage.

(* would be interesting to know what the actual error bars on that estimate are.)

Today's NYT update contains a timestamped map like I've been asking for. However it only has the last military fix west of Malaysia after 1:34 of flight, then the satellite arcs for +7.5 hours. None of the reported hourly locations in the intermediate hours.

The sidebar says "A satellite picked up four or five signals from the airliner, about one per hour, after it left the range of military radar", which is in line with the WSJ article describing hourly messages. However the WSJ article says the messages include precise location and velocity data, whereas the NYT article says "The older satellite communications box fitted on the plane has no global positioning system ... But investigators have managed to calculate the distance between the “ping” from the plane and a stationary Inmarsat-3 satellite".

Also according to this article, the position calculation doesn't come from signal strength but rather "the angle from which the plane sent it". You can actually see the angles in the government position image at 40°. (One wonders what the error bar on that measurement is.)

I haven't seen any explanation on why there's such a big gap on the ring centered on Malaysia. it's nearly 25° of latitude or 1700+ miles. Do they exclude that from the possible range because of the satellite geometry? Or are they excluding it based on radar or other satellite location data?

I haven't seen any explanation on why there's such a big gap on the ring centered on Malaysia. it's nearly 25° of latitude or 1700+ miles. Do they exclude that from the possible range because of the satellite geometry? Or are they excluding it based on radar or other satellite location data?

Somebody said upthread that it was excluded due to having radar for the area which shows no airplane. The middle of the arc would be roughly (though not quite) right for Butterworth airbase which both naturally has radar and was earlier tracking the flight. However, that is only what was put forward above and which I'm repeating.

Re: big gap / two corridors
We've talked a bit about it further upthread actually. If you look again at the coverage of the satellites (linked here before) you can see that Malaysia is covered by two satellites, the data of IOR (blue) and POR (pink) overlaps. The last ping must have been picked up only by IOR, not by POR or AOR-E (yellow, over the Atlantic). So bits of a theoretical perfect circle can not be valid.
They also exclude bits of the circle due to fuel load. Possibly to radars and the SAR mission in that region. Hence we end up with two corridors.

US investigators are reported to believe the initial off-course left turn which precipitated this entire chain of events was likely pre-programmed into the plane's autopilot. That would basically require the pilot to be involved.

From the Jakarta Post:
In a development that could make the mystery surrounding the missing Malaysia Airlines plane more puzzling, the Indonesian Air Force has revealed that its radar in Sumatra, which is closest to Penang on the Malaysian Peninsula, did not detect any aircraft in the Malacca Strait area under its coverage, around the time Flight 370 was lost early last Saturday.
This was from Friday.

I know that the likely best outcome we can expect from this is finding the wreckage and being able to give some sense of closure for the families and friends.

But this past week has just been *so* weird and unprecedented that I can't help thinking how awesome it would be if the flight was hijacked, and the passengers are all safely released, after the Uighur hijackers get their ransom demand paid via Bitcoin, with the destination wallet and transactions being filtered by an underground crime ring in Crimea, who it turns out Edward Snowden has been freelancing for (when not breaching credit card numbers at Target), and that the Bitcoins are eventually used to buy flights on Virgin Galactic - which is then itself hijacked repeating the cycle. Watching CNN trying to find an expert to explain all that would be worth the price of admission. Plus the passengers would be home and safe. Huzzah!

MH370: life on hold for brother of missing Malaysia Airlines passenger
"I don't think I can get anything done," he said. His thoughts wander and at times he feels sick.

"This long wait is taking its toll on everyone. I don't really want to think about it too much; every time I think of it, it's hard to think through everything."

Wang's (not his real name, because he wishes to protect the privacy of other family members in China) sister is several years older than him and throughout their childhood she was his protector. She was just 16 when circumstances forced their family apart, and for several years she effectively raised him. "It was just the two of us," he said.

Even when he grew up, she would go out of her way to help him with anything he needed. Although he moved abroad some years ago, his daughter recently spent six months living with her aunt.

His sister had grown up into a lively, outgoing woman, "always busy doing things; always going places." Her son has told him she had been in Malaysia for business.

At first, no one dared to break the news to their elderly mother. But when she tried to call Wang's sister, and could not reach her phone, relatives were forced to explain that she was missing.

Well, you would have two points if two satellites received information about MH370 at the same time. The two points in the globe would be the two places where both bits of satellite information are true. I realize that image shown only marks the location of one satellite, but perhaps there is a reason the other was left off...

Yeah, irrational/deliberate crew activity is a deeply unsatisfactory explanation because it could be used to explain just about any kind of incident. And there is no evidence whatsoever of hijacking and it would have to have been very very lucky or very very sophisticated hijacking for there to be none.

MH370's original heading off the NE coast of Malaysia, waypoint IGARI, is an intersection of national airspace boundaries. Malaysia, Singapore, Thailand, Cambodia, and Vietnam all meet there. If you want to cause maximum confusion, that seems to be the place.

If you look at the timing, the plane took off and reached cruising altitude over the middle of the country at the 20 minute mark, so seatbelt signs would be on until then. 20 minutes later, the Air Traffic Control reported its last contact just off the coast. Before that, while it was still over land, the ACARS went off. After the last ATC report, the transponder went off. Then the indication on radar that the plane was changing course.

That's a lot of activity in a short amount of time if we're talking about an unauthorized intrusion into the cockpit at a time when the flight attendants are getting ready/serving the evening meal and at least some passengers could still be expected to be awake.

According to the New Straits Time the investigators re-enacted the suspected flight path to compare the radar and satellite data with data from the missing aircraft. From the article: "The official said the new findings generated data identical to that which is believed to show the missing airliner [...]."
And: "That is why we can conclusively say which two possible directions the plane flew [...]." (Emphasis mine)

Here's the link to the livestream.

Many interesting questions raised by the press. The authorities actually confirmed a few things that were already reported.

Families of both pilots have been questioned. It was confirmed that the pilots did not specifically ask to be scheduled for this flight together.
The police has the captain's flight simulator and is checking it out.
They refocus on the backgrounds of crew and passengers but said at least twice that they are treating everybody the same, alluding to no specific suspects. But not all countries got back to them with background info yet. They also said that intelligence agencies didn't reveal any suspicious details about the passengers. He refused to name which agencies.

It was confirmed that one of the tracking systems was switched off before the last official communication happened.

The suspected flight path has been re-enected with a flight simulator. The data gained suggests that it was MH370's signal that was picked up by radars and the satellite, although he used the word "could" and made no definitive statements, unlike the NST article.

They are pretty certain about the corridors and said the data was analyzed independently by experts from the UK and the US and later compared. It turned out that both parties came to the same results. They also said they made calculations how far the aircraft could have flown based on different speeds. It was confirmed that the aircraft had the regular, expected fuel load.

They said the cargo load did not contain anything hazardous. That was a bit of a round about answer I thought. The reporter asked a more general question, if they knew what was loaded and about the cargo manifest IIRC.

They thanked all the countries involved for their help so far, but asked "other countries to come forward" with data. So there might be some tension on that front, as the defense systems of the region seem not exactly the state of the art. They hope more data will narrow down the search area, but don't prioritize either corridor so far, it seems.

1. Search and rescue operational update
a. The search and rescue operation continues to be a multi-national effort, led by Malaysia.

b. Malaysian officials are contacting countries along the northern and southern corridors about MH370. These countries include: Kazakhstan, Uzbekistan, Kyrgyzstan, Turkmenistan, Pakistan, Bangladesh, India, China, Myanmar, Laos, Vietnam, Thailand, Indonesia, Australia and France. Officials are requesting assistance from these countries.

c. Malaysian officials are currently discussing with all partners how best to deploy assets along the two corridors.

d. Malaysian officials are also asking countries to provide further assistance in the search for the aircraft, including: satellite data and analysis; ground-search capabilities; radar data; and maritime and air assets.

e. Both the northern and southern corridors are being treated with equal importance.

2. Update on the police investigation into MH370’s crew and passengers

a. As per normal procedure, the Royal Malaysia Police are investigating all crew and passengers on board MH370, as well as engineers who may have had contact with the aircraft before take-off.

b. Police searched the home of the pilot on Saturday 15 March. Officers spoke to family members of the pilot and experts are examining the pilot’s flight simulator. On 15 March, the police also searched the home of the co-pilot.

c. We appeal to the public not to jump to conclusions regarding the police investigation."

I can't help but think that it would greatly help if the US could dispatch a few 688 fast attack subs to the search areas to listen for the pings from the black boxes. I realize the search areas are enormous and the 688s are probably busy tracking other subs, and I'm guessing the US doesn't have any "spare" subs, but nothing can hear in the depths like an attack sub.

I'll be the first to admit that, at this point, things look really grim, but I sure wish they could find those recorders.

WSJ: What Satellite Data Reveal About Flight 370's Location, an update with little new info. They correct one previous puzzling thing they reported: "However, the 12-year-old Boeing jetliner wasn't configured to broadcast those definitive points of data, people being briefed on the investigation say, as they first believed." That puts them in agreement with the recent NYT story that the satellite data does not include GPS fixes after all.

Still doesn't say anything about the locations of the 5 hourly pings. I'm very curious to see them because they should let you estimate the plane's speed and whether it flew a direct course, even if it's just more angles to the geostationary satellite. Maybe the data is so confusing or incomplete they don't want to publish it.

I have a nagging feeling that part of why information is so slow to come out is that it is embarrassing to the air defense networks. I'm sure it's painful for Malaysia to admit they don't have radar sufficient to track a target like this.

Although I'm not so sure it relates to the flow of information we are receiving in this incident, it does seem apparent that many military radar networks are not all they're cracked up to be. This is true in the US too; why was it so difficult to determine the locations of the planes on 9/11 after they turned off their transponders? The report plays up the confusion amongst the various FAA centers, but never seemed to ask the question "Why did NORAD not pick up on four airliners flying around the country with their transponders off?" It's clear that countries are very sensitive about revealing any details of their air surveillance networks, but the bits and pieces we do get tend not to inspire great confidence.

From the end of this article on the Guardian:
The satellite "pings" that were last read at 8.11am on Saturday – some six hours after Malaysian military radar last detected the aircraft over the Malacca Strait at 2.15am – could still have been transmitting data from the ground, if the plane were to have landed, said Malaysia's civil aviation chief, Abdul Rahman.

"The plane can still transmit pings from the ground as long as there is electrical power," he said.
I haven't heard this mentioned before in this thread. I suppose its not surprising that they can ping on the ground, however unlikely in this scenario.

TWinbrook8 mentioned Australia's JORN (Jindalee Operational Radar Network) upthread and although it can detect "planes as small as a Cessna 172" and "has an official range of 3,000 km" (both from the wiki), this JORN fact sheet [PDF] states on page 3: "JORN does not operate on a 24 hour basis except during military contingencies.

This is a nice map showing which parts of the ocean on the southern corridor are actually covered. It shows the Inmarsat satellites, point of last satellite contact and Australian radars. Source: Mark Reynolds, PhD. Professor of Computer Science and Software Engineering at The University of Western Australia.

Explanation of the pic:
The red line marks last contact of IOR with MH370 at 8:11am. The aircraft could have been at one point on that line at 8:11. The blue line marks how far the aircraft could have flown by 8:11.
The pink line marks where coverage of POR stops. The plane could not have been east of that line, if it had been POR would have picked up on it at 8:11 as well.
The white circle around Australia is an estimation of JORN's reach.
There also is a green line far to the west, where the plane can not have been, or it would have been detected by AOR-E.

I almost wonder if it did cross over land, was identified on radar by another country, and then because there was no communication from the plane it was shot down and whoever did it is trying to keep it quiet.

jason_steakums, unless it was shot down in a VERY remote part of the world without social media (which I guess is possible), that doesn't seem like a likely scenario to me.

Right, would whoever is piloting stick to the flight corridors? because IGREX on route P628 leads directly over Port Blair and the Indians have already said they didn't see it. IGREX is also the border between Malaysian and Indian airspace so if the pilot wanted to skirt the boundaries, flying from that point north via waypoints follows the perimeter of Indian and Burmese airspace and maybe the limits to their radar if anyone was watching in the middle of the night. I really have no idea, I'm just looking at the chart.

Possible over land ('northern corridor') scenarios:
  1. plane evades radar
  2. radar is not functioning (turned off; apparently that happens)
  3. data is missed; plane is tracked but not identified
  4. plane is given safe harbour/final destination by a country that colludes in the plan (conspiracy)
Anything else?

That's another thing I'm wondering about, what are the odds that US spy satellites were able to confirm what happened to the plane but aren't releasing the info so as not to tip their hand on their surveillance capabilities? I wouldn't be surprised if there were spy satellite eyes on that part of the world.

I'm not sure why anyone would be confident in the ability of satellites to detect an explosion. Such a capability severely depends on how bright the explosion is and where it occurs in the atmosphere. These satellites are fine tuned to detect specific types of events, usually rockets or nuclear explosions, so it's super non-obvious that they would be able to detect the in-flight breakup of an aircraft. I know of no such events that have been detected by satellites.

Again, the military is not magic.

"they know based on radar where it flew for approximately 7 hours."

Do you really think they know where it flew? It reportedly left Malaysian airspace (= areas covered by Malaysian radars). Did you mean satellites? The data from the satellites does not necessarily give a flight route if it was incomplete, and more importantly it was not shared with the public except the last handshake at 8:11am.

About satellites detecting explosion, see my comment here; the US said earlier in the week they have infrared detecting satellites and they didn't see an explosion -- at least in the immediate area, now, who knows if they checked far away places like Kazakhstan. But I imagine they could go back and check now?

Ok, if Richelson claims they have detected aircraft explosions in the past I'm willing to give some credence to it, but slightly grudgingly since he is often working with non-public sources. I guess that's just how it goes when it comes to stuff like this.

The statement alone that the satellites didn't detect anything is not particularly useful on it's own, since it doesn't tell you whether the satellites would have been able to detect the hypothesized explosion.

Series of Errors by Malaysia Mounts, Complicating the Task of Finding Flight 370

The radar blip that was Malaysia Airlines Flight 370 did a wide U-turn over the Gulf of Thailand and then began moving inexorably past at least three military radar arrays as it traversed northern Malaysia, even flying high over one of the country’s biggest cities before heading out over the Strait of Malacca. . .

Senior Malaysian military officers became aware within hours of the radar data once word spread that a civilian airliner had vanished.

The Malaysian government nonetheless organized and oversaw an expensive and complex international search effort in the Gulf of Thailand that lasted for a full week.

Only on Saturday morning did Prime Minister Najib Razak finally shut it down after admitting what had already been widely reported in the news media: Satellite data showed that the engines on the missing plane had continued to run for nearly six more hours after it left Malaysian airspace.

Grief, anger and despair: inside the Beijing hotel where relatives of missing MH370 passengers are staying.
On Friday, security guards tussled with several male relatives of the missing passengers who wanted to allow journalists into the hall to witness the poor treatment that they were receiving.

“It’s all bull****,” a man named Wang said of the conferences. “All they do is stall.”

Some family members said they were told not to speak with journalists, while others say they don’t want to give their names or appear on TV because they are shielding older and younger relatives from the news that someone they love was on the plane.

I'm intrigued by the idea that no one wants to confess that their radar couldn't have tracked them over land. So they are letting everyone assume the plane must have gone down in the ocean and all is lost. Of course that leads me to they could be marooned in some inhospitable remote location desperate for help which is agonizing also. I feel so bad for the families. The unknowing must be unbearable because the imagination can conjure such horrible scenarios.

Senior Malaysian military officers became aware within hours of the radar data once word spread that a civilian airliner had vanished.

Unidentified radar data that showed an uncertain contact. The more accurate radar paths have only been reconstructed afterwards from data from multiple radars. Meanwhile there was a complete loss of communications to the aircraft which very strongly indicated that it had suffered a catastrophic event. Thus the SAR effort was split into two areas.

Aviation experts said that a trained pilot would be the most obvious person to have carried out a complicated scheme involving the plane. Yet for a week after the plane’s disappearance, Malaysian law enforcement authorities said that their investigation did not include searching the home of the pilot, Zaharie Ahmad Shah.

Hindsight much? These aviation experts are only saying this because of the unprecedented use of satellite pings to verify that the plane had not suffered a catastrophic event.

Only on Saturday morning did Prime Minister Najib Razak finally shut it down after admitting what had already been widely reported in the news media

It had been widely reported in the news media because the data was being used to assist in the search effort and had been widely disseminated to US officials.

Most of the media reaction seems to reveal an attitude where information that is not disseminated to the public means that it is either not known to the investigators or that it is being suppressed somehow.

It's interesting to note that this kind of public confusion and media storm happens almost every-time a plane crashes and that the parties with the most experience about this kind of stuff, namely NTSB, FAA, Boeing and Rolls-Royce have not criticized the Malaysian effort at all. Not that I would expect them to at this point unless the effort was utterly and completely mishandled

Just looking at the map and the northern corridor. The investigators might assume MH370 could not have been in Chinese airspace at 8:11am, assuming strong aerospace defense. So a big chunk of the arc would not be valid. Kyrgyzstan, Uzbekistan, Tajikistan, Afghanistan and Kazakhstan would be left towards the west and Myanmar towards the east. Getting into Myanmar would be a fairly straight flight, yet it would be too short for ~7 hrs. There is another possibility, as Thing reminded us, the satellite can register pings even from an aircraft on the ground if it remains powered up. So....land it somewhere closer, yet on the northern arc, and let it run out of fuel. Does that even work with planes?

Now how to get to the western territory on the northern corridor from the last suspected point of contact at 2:15am? India was quick to posit no aircraft could have entered its airspace without detection. Which is probably not exactly true, as it was reported that the Indian islands are not monitored at night for example. Were the plane to fly around India and through Pakistan instead, it is certainly possible to make calculations about speed and fuel that could narrow down where a plane flying such a route could be at 8:11. That would be a long flight, probably longer than 7 hrs, so unlikely to reach any point on the northern arc by 8:11.

Another route could be through Bangladesh, Nepal and the Himalayas. The mountains lead towards the western territory mentioned before. It looks like a difficult terrain but the flight duration could be about right.

If all the pointers we have turn out to be true, this was a skilled person/group/agency/organization with solid knowledge of aviation including aerospace defense. If s/he/they know so much about how to do it in Malaysia, why not have the knowledge regarding other countries and their airspace/defense as well?

if this wasn't actually a real world situation (ie: a fiction), I'd say I loved where it was all heading. Instead, it's more of a Shrodinger's Cat sort of situation. Somewhere, some place, there's a plane full of passengers (or the remnants thereof) -- with uncertainty the only real certainty.

The white circle around Australia is an estimation of JORN's reach.

JORN doesn't see a full circle. The radar station watching that direction (JOR2) see about 180 degrees, centered north, so anything south of 23.6° S is going to be invisible to JOR2. So add a bit to that RED arc.

It also seems that whoever was flying was aware of JORN -- flying across Malaysia kept the plane well out of reach.

Not that I would expect them to at this point unless the effort was utterly and completely mishandled

Maybe not even then -- what they try to do is, in the background, explain why the matter was handled poorly, what could be done in the future, and if you need our help, please do ask. The NTSB has gotten vastly more cooperation over time with this approach. Part of this is that the NTSB and the UK's AAIB have a very strong and carefully defended reputation of completely honesty in their reports, including saying "we don't know" when they simply cannot find out what happened.

Which is probably not exactly true, as it was reported that the Indian islands are not monitored at night for example.

The outpost radar stations may not be monitored at night, but India has more than enough air traffic that the mainland ATC radars are being monitored 24x7x365.

Basically, to get to the "'Stans', that plane head three choices. Fly over large part of India, fly over large parts of China, or fly basically the China/India border and be seen by both of them.

The only way I see them going north and not being seen is if they go very low and land/crash in something like northern Myanmar or Bangladesh -- and even then, that's dicey. I'm not saying it's impossible, but it's dicey, and if they dropped low to get away from radar, the fuel burn went way up *and* the ground speed dropped to at least 350kts, probably lower, depending on how low they went. At that speed and fuel burn, they probably don't even make Bangladesh.

Finally, Malaysia's AD radars are one thing, China's are another -- they are known to have several OTH radars (and, like the old Russian Woodpecker, occasionally cause problems for HF radio users.)

I second that. There's no evidence of mishandling of the search and rescue or subsequent investigation. We don't know enough about the behind the scenes to really make a judgement. My gut says give them the benefit of the doubt.

However, It does look like the Malaysian officials saddled with the communication aspects aren't accustomed to the onslaught of the international press at this intensity. And possibly some people (in Malaysia and out) don't know how to keep their mouths shut or their opinions to themselves. (I guess that last part isn't much of a revelation.)

double bubble, my understanding is that ACARS usually transmits a rich data stream with lots of info about the engines etc, and *that* stream was turned off. Whoever turned it off didn't realize (and it sounds like even the officials may not have realized until the satellite company came to them?) that the unit was still pinging, i.e., just sending out what they're calling a "handshake" signal that didn't include any further data.

I think I read somewhere (sorry, will try to find link) that the satellite ping was not from the ACARS system but was instead something called Swift64, which is a communications system that uses the Inmarsat satellites. (I believe ACARS uses satellites from Iridium.)

I don't know anything about Malaysian culture. Do they typically promote the concept of family pride and family shame? If someone were to commit suicide, would that be seen to reflect badly on their family?

It's pretty outlandish, I realise, but could either the pilot or co-pilot decide that flying an aeroplane that just disappears into nowhere be a way of saving face for everyone involved? Their disappearance left a mystery?

If they placed no value on the lives of others (suicidal people are often not thinking clearly), they could do exactly what we've seen here. Take the plane off radar, disable all contact with the rest of the world that they were aware of, make a rapid course adjustment to confuse authorities and then fly into the middle of nowhere, ditching into the sea when the fuel ran out. They'd leave behind a mystery. They might even convince themselves that the hope that their loved-one was still alive would be better than knowing that they were dead.

YAMWAK: This is based on my own personal experiences as someone with mental health issues, who has been suicidal, and who has been diagnosed and treated in Malaysia (and elsewhere). The caveat is that this information is at least 10 years old, and I don't know if anything's changed since then.

Awareness of mental health is sorely lacking. Your personal self-care is not seen as a priority. My school's policy was always "unless you're bed-ridden or severely contagious, show up". My anxiety and depression was derided as "it's all in your head, you're making it up" - while tons of people in my school were having bouts of "hysteria" from just being so stressed. It doesn't matter if you're stressed, or sick, or sad - achieve anyway. Get good grades. Don't slack off.

One of my classmates also had mental health issues (incidentally we shared a psychiatrist, though we were never friends) and ended up dropping out of school (I think she moved somewhere else). My teacher made a quip about how he hoped she wouldn't take the SPM(O-Levels) at our school else we lose our 100% pass rate.

I was suicidal at 11. Tried to cut my throat at school. The only other person who saw me was another student who said "you will go to hell for that". Even when I was open about my own struggle and how I needed help, it wasn't until I was approaching 17 and getting nightly panic attacks that I got my diagnosis - and even then I was stigmatized for it.

People don't talk about suicide or mental health issues. At all. My psychiatrist was a pretty great guy, but I was also shuttled around multiple doctors (my parents wanted a definite diagnosis) and every doctor diagnosed me with something else: schizophrenia, Tourette's syndrome, neurological disorders, whatever. It wasn't until I got checked out at John Hopkins and got the same diagnosis as my first psych that my parents were satisfied.

(And now, 10 years later, there seems to be more with my mental/hormonal health than we know about. I have a letter from my Australian psychiatrist telling me I'm a "diagnostic dilemma".)

I am really wary about the possibility that this was pilot suicide. Not because I don't think that's the case (I'm trying not to have any personal theories about it), but because I have no confidence in the ability of the Malaysian authorities or public to be able to figure out any signs of suicidality or depression. The international media as it is has been abysmal in their coverage (and blaming the Malaysian authorities for it) and they're not always the greatest with mental health cases either, but at least in places like Australia or the US there are stronger support and advocacy networks for mental health. Malaysia? Not so much.

Sometimes people are suicidal and you have no idea. Sometimes people express suicidality but aren't actually keen on following it. Sometimes you are in situations like much of Malaysia where you don't have space to talk about your mental health issues, your main focus is on the job, your personal problems stay out of it.

It fits, but I think the problem with this is that we're assigning motives as a result of the conclusions we know now. If this was a suicide, then at the time it was being thought of, the person who piloted the plane would have been able to anticipate the response of not only the local government and media, but also the response of a number of international governments and media. They would have be certain that the plane would never be located, and that there would be great confusion, instead of being seen as a mechanical failure, suicide/mass murder, terrorist incident, or something else entirely.

Of course, this doesn't discount the possibility of suicide, but I don't think it's any more or less likely than it was before.

From roomthreeseventeen's link:

Way-point Tracks
• The use of way-points to the navigate are conjecture. They happen to line up with the direction indicated by the primary radar returns and Inmarsat data to the north.
• While many believe the aircraft was under control - we cannot conclude if these way-point were used, or just along the path.


That's rather interesting, as the use of waypoints suggested a knowledgeable person still flying the plane several hours after it stopped communicating.

Re: "use of waypoints suggested a knowledgeable person still flying the plane several hours"

IGREX is named as the last waypoint, the time was 2:15am. That's roughly one hour after last comms with ATC at 1:21am (on regular flight path's waypoint IGARI over to the other side of the peninsula).

There's a couple of nice maps in the thread roomthreeseventeen linked. I can't figure out how to link directly to the comment, but it's reply 45, by user socalgeo. He explains his calculations more fully, but:

Here he figures the maximum flight time radius from the point of last contact, and offers this map -- which shows the max straight line distance the plane could have gone, plus the two arcs where the last ping could have come from, all this superimposed on radar coverage. It shows what we've talked about -- that to get to the northern arc, you'd have to fly through dense radar coverage, with the least-covered area being Myanmar.

Here he figures the max flight distance if the plane turned south from its last known point... on such a path it would not have to cross any radar, and it would put it nicely at the southern arc.

Suicide would require either the pilot or co pilot (depending on who was committing suicide) to subdue the other person or otherwise render them unable to control the airplane. Is this plausible?

Re-reading, I think I've mis-stated the exact method that yields the last map - he says the second map is "a scenario where the plane continues to the IGREX waypoint and then turns south, skirting the Indonesian radars at Aceh, and then when clear taking a straight shot to the arc. The blue line is the flight path....it lines up right with where they have said they are searching." (But interested people will do well to just find his full comment.)

I wonder where on the timeline the climb to 41K and then "irregular" dropping was. Because people have been assuming that depressurization would automatically knock out the passengers... but the oxygen would deploy. So if you wanted to disable everyone else on the plane, depressurizing and then tumbling the plane around is a pretty good way to do it, especially to keep crew members from getting to the portable oxygen before they pass out. So if it occurred before the turn back across Malaysia, it may have had the goal of silencing the passengers and explain no text messages.

I can mostly make the suicide thing work in my head, if I assume the person doing it had the highest goal of never being found. Disable the passengers and crew, maneuver through the inhabited areas and radars, and then put an autopilot course for Antarctica and take off your mask. Or maybe make an error with your own oxygen and pass out before you can take the dive into the sea.

But *damn*, that's a lot of anger. Not just depression, but really intense focused anger. You'd probably have to kill the other pilot personally, and then probably deliberately kill the passengers or at least terrorize them, all over a period of hours, and there are a lot of ways to kill yourself with minimum chance of detection with less effort. Depression can turn outward into violence, but the targets are usually people who the person thinks have wronged him.

People brought up the Fedex attack, and that's a good example -- you had a guy who was about to be fired, and not only did he want to kill himself he wanted to destroy Fedex for firing him, which explained the target and violence of the attack. So far we don't have any such thing for either pilot, no known job difficulties. Maybe something will come out that will give a sufficiently powerful motive. Being pissed about Anwar hardly explains it -- that it's vile behavior on the part of the Malaysia government is pretty much the opinion of any decent person, not a sign of extremism.

The autopilot ("flight management computer") navigates using waypoints. So it could imply the pilot was flying the plane, or the pilot could have entered in the waypoints before becoming unconscious, or a hijacker could have had a list of waypoints in his pocket to type in.

One other thing -- the default behavior if you reach the last waypoint is for the airplane to circle the waypoint and wait for further instructions. So if the pilot is unconscious it would be plausible that the plane reached the end of its program and just circled in place for hours before running out of fuel. In that case the searchers are looking in the wrong place because they seem to be assuming the plane was flying in basically a straight line in some direction, not circling.

Or the goal could have been to embarrass the Malaysian government. The pilot or copilot kills the other, programs waypoints into the autopilot, and depressurizes the plane. Everyone dies quickly, and the plane flies to the south Indian Ocean where where the pilot assumes it will never be found (not expecting the satellite data that has complicated the search). The plan would have been to make it look like it crashed shortly after the last radio contact, and the Malaysian government would come off very poorly after being unable to find the plane where it "obviously" must have crashed.

It's also been mentioned elsewhere that the person in control of the plane might have changed his mind at some point after turning the plane around, ie he had second thoughts about whatever he'd planned to do with the airplane/passengers/cargo and having committed a despicable and monumental crime, the only way out would be to ditch the airplane in deep water where his actions would remain a mystery. For someone who absolutely loved flying, changing the heading to fly over the vast Indian Ocean (southern arc), setting the autopilot and flying on until the fuel ran out might be a peaceful ending. I'm not explaining this very well but I can't find the original post

But the authorities have paid scant attention to the southern arc, not even contacting Australia to search with Jindalee so I've also discovered there is a runway that can accommodate a 777 in northern Burma and that would explain the last ping although nobody on any side up there would want to piss off the Chinese.

No info regarding the earlier pings was released. And it was stressed how both corridors are being treated with the same importance. The pings must have been analyzed by now, most likely at the same time they analyzed the 8:11am ping. If the data for the time 1:20-8:11 was received, it could be that it leads to an inconclusive analysis. That might explain why the SAR efforts slowed down a bit and we haven't seen much movement towards search sites in the Indian Ocean. The last two or more pings being on the same circle, would suggest a landing on land. But not necessarily.

This is all nuts. Why spend so much effort to avoid radar if you're going to let yourself run out of fuel in the middle of nowhere west of Australia? The only thing that makes sense is the northern corridor. Maybe we're giving too much credit to the air defense networks of India and China and a 777 really could fly low over their airspace without detection...

SAR efforts in that southern corridor would be pro forma anyway. There is too much ocean and too much time has passed. Finding the wreckage would be a fluke unless they have information they aren't sharing about where in that corridor the plane would have been.
posted by Justinian at 6:18 PM on March 16, 2014


One other thing -- the default behavior if you reach the last waypoint is for the airplane to circle the waypoint and wait for further instructions. So if the pilot is unconscious it would be plausible that the plane reached the end of its program and just circled in place for hours before running out of fuel. In that case the searchers are looking in the wrong place because they seem to be assuming the plane was flying in basically a straight line in some direction, not circling.

Is this really possible? It seems so straight forward.

A 777 at 5000 feet is going to be pretty loud. Heck, the MD-80's that pass over my house at 10k are already noisy enough, even in the dark I think a 777 would be notable. Unfortunately that article gives no indication of why unnamed investigators might think the plane was flying low.

The intermediate satellite data would be useful to see how far into the open ocean it flew. If it stays at the same range then those arcs are probable tracks, and either it crashed at the most distant ends of those arcs (or it landed and continued transmitting closer). If it flew into the ocean and then back away from the satellite, the focus would be on the closer end of the last-position arcs.

Re: "If it stays at the same range then those arcs are probable tracks, and either it crashed at the most distant ends of those arcs (or it landed and continued transmitting closer)."

If it circled around the same spot for a significant amount of time, several pings could indicate the same distance.
posted by travelwithcats at 6:55 PM on March 16, 2014


The corridors we're seeing are just a mental aid. The plane was in only one spot along those arcs at 8:11am.

Yes I understand that. But between 1:27 and 8:11 it can either 1) Fly roughly along the arc or 2) Fly off the arc, towards the ocean and then back out to the arc, so those seem like worthwhile scenarios to consider (I guess I'm also going on the assumption that the plane was flying at fixed mach number and not intentionally slowed down). Landing early or circling are clearly possible but seem hard to justify, but to be fair none of this is easy to justify.

Agreed, knowing the earlier pings (and therefore the inferred arcs/estimated positions of the aircraft at time of ping) would be helpful to make assumptions about the flight path of MH370. We could establish average speed from that and possibly even exclude an unlikely corridor. But like I said a few comments upthread, there are reasons why that info is not made public.

From the Guardians live update site:

I’ve just spoken to Sidney Dekker, a professor at the Safety Science Innovation Lab at Griffith University and expert on aviation safety.

He dismissed the idea that flying at 5,000 feet would put extensive strain on the airframe, as some have suggested: “The only really relevant effect is a dramatic increase in fuel use - its range would be very much shortened by that; probably halved, at a very rough guess.

“Other than that, it would be perfectly capable of flying - if you go into Heathrow you are circling at 5,000 feet before they let you land,” he said.

He added that it is difficult to overstress a fly-by-wire (rather than mechanical) plane such as the 777, though he did add one caveat: if a plane was in an extremely fast dive and abruptly pulled out of the dive at its bottom, that could cause problems.

But perhaps more pertinently, he pointed out that altitude readings taken from radar recordings should be treated with extreme caution: “Particularly over oceanic areas, radar coverage is extremely unreliable and partial,” he warned.

Finally, he added one note of caution regarding the focus on the airline crew, based on his years of examining aviation disasters.

“In the absence of knowledge, it is so easy to blame it on the little guy - particularly if he isn’t there to answer back. It is so easy to say ‘the crew must have done something wacky,’” he said.

Let me tease futz* a little more by expanding on my Fukishima comment: we're surely all aware of Tepco's incompetence and the controversies about unethical things its done in the past. And I've read that the clean-up effort was shopped out to the Yakuza. They, of course, are even more unethical, hiring the homeless to do the work and not bothering to adequately protect them, for instance. And the Yakuza aren't much different from the Sicilian Mafia, who are known to dump toxic and radioactive wastes willy-nilly along Africa's coast, violating all sorts of laws. Nor so different from the Russian Mafia, who sold nuclear warheads during the Soviet breakup to the highest bidders.

So here we have a metric shitton of highly radioactive waste and spent fuel rods, a corporate owner that is at best negligent and at worst will do anything to make or save a buck, and a criminal gang with direct access to really bad shit, an urge to make dirty money, and no scruples whatsoever.

Plus a very large and powerful aircraft that may be hauling several tons of lithium batteries**, which can be made to go off like a bomb.

Plus incredibly sophisticated hijackers who have potentially routed the craft to terrorism central.

Put it all together and what do we have? Paranoid thinking? Sure.

On the other hand, everything that has been confirmed as true so far is no less crazy.

Scary. I hope my fevered imagination*** is an order of magnitude more wacko than what has already happened.

*Note to futz: don't take this post seriously.

It seems that the Acting Transport Minister is preparing a briefing for MPs, but not Opposition ones.

The letter translated, reads: "the Right Hon member is to be informed that the Ministry [of Transportation - that's their letterhead] will hold a briefing regarding the incident of the disappearance of Malaysia Airlines flight MH370 to be tentatively held at the following:

Date: 18 March 2014 (Tuesday)

Yes, taz. Sorry, taz. You too, futz.

J, the leading theory is that the airplane was jacked, right? So then the next concern is "what do they intend to do with it"? Well, one of the bigger terrorist threats has been that of dirty nuking a city. Fortunately, matériel, delivery, and effective dispersal have been their challenge. If this was a successful hijacking, two of those problems might now be solved. Corruption at a nuclear disaster site provides the missing piece.

It'd work for a Clancy novel or Hollywood movie.

Anyway, enough of that. It's wild speculation. Granted, that's all we've got for any explanation right now, but this one is particularly grim. I'm done with it.

One of the horrfying things about the WTC attack was that normal planes with no special weaponry, full of everyday people, were turned into weapons that took down buildings. That aspect of the attack was as important as bringing down the buildings themselves, from a terror point-of-view. And it worked: Witness the vast awfulness that is the TSA, and the sad police state that has arisen from the ashes of the USA.

Had the 9/11 perpetrators used planes they had, say, stolen from a "banana republic" airline, loaded with explosives, and flown into buildings, the towers falling would have been just as horrible, but the state response would have been quite a bit different.

The goal of a "nuclear incident via plane" is to make the nuclear part happen, that's the real terror bit. And if that's the case, hijacking is about the worst way you could go about procuring a plane. Getting the plane is the least of your worries.

If a 777 goes missing with 240 people aboard and there is even a 1% chance that it might have been successfully stolen (ie, it could be flown again), if I'm Government/Boeing/Rolls Royce, I'd be doing what I could to really grill any 777 flying into my airspace for the next few years (at least) to make sure it's what it says it is. So, in addition to the very risky and prone-to-failure part of getting the plane in the first place, you now also have a shaky platform for delivering your nuclear threat.

I think all scenarios involving theft of the plane, either for re-use or re-sale, suffer from these two weaknesses.

However, Flight 714 is a pretty obvious red herring; a piece of deliberate misinformation, perhaps. The real key to the mystery lies in Tintin in Tibet.

"Alright, good night" comes around about half an hour after take off, shortly after the plane reaches cruising altitude and on the point where they have just handed off from Malaysian airspace and are yet to check in with Vietnam.

That's incredibly common on handoffs. No sense not being polite, right? Plus, it acts as an acknowledgment of "I understand you are no longer then controlling ATC and that I have been directed to another."

So, you get things like this all the time.

Dramatis Persona:
ZAU: The Chicago Area Traffic Control Center
ZKC: The Kansas City Area Traffic Control Center
AA1186: A plane flying from Chicago to St. Louis

Scene: FL280, heading southeast, near Vandalia, IL.


ZAU: "AA1186, continue as directed, contact Kansas City on 127.1"
AA1186: "Roger 1186, Kansas City 127.1. Good night."
ZAU: "Good night."
AA1186: (switches to 127.125MHz) "Good evening, Kansas City, AA1186 entering."
ZKC: "AA1186, good evening, squawk 3252 and ident"
AA1186: "3252 and ident, 1186"
ZKC: "AA1186, radar contact, continue as filed."
AA1186: "Roger, 1186."

And, AA1186 has been handed off from the Chicago Area Traffic Control to the Kansas City ATC.

So, ending with "good night" is very typical. Up until that point, nobody would think anything is out of the ordinary. The Vietnam area controller, however, may well have started making phone calls when they didn't get MH370 checking in as expected, the question is how long would they have waited before contacting Malaysia's ATC and asking "Hey, we have MH370 filed through here, they haven't checked in, can you reach them?"

That's common because sometimes people forget to change frequencies on a handoff. Normally, you have two radios, and you leave one on your last frequency and change the other to the new one. That way, if you screw up that change, you can be contacted on your last known frequency.

Daughter returns to Malaysia to await news of her father.
MELBOURNE - The daughter of the pilot who flew the missing Malaysia Airlines flight MH370 was living in Australia when the plane mysteriously vanished from radar screens.

Ms Aishah Zaharie, who lives in Melbourne, has returned to her family in Malaysia as she awaits news of her father, Captain Zaharie Ahmad Shah, Australian news website news.com.au reported.

Ms Aishah, 27, graduated from Deakin University in Geelong in 2010 where she studied architecture. Her boyfriend Hazwan Anuar, also from her hometown of Shah Alam in Malaysia, graduated from Deakin University in 2011 with a masters in the same field, reported the website.

Ms Aishah and her boyfriend both studied at the International Islamic University of Malaysia in Kuala Lumpur before moving to Victoria, said the report.

A friend of Ms Aishah, who did not want to be named, was quoted as saying that speculation about Capt Zaharie was "killing the family".

"On what the international media wrote about Captain Zaharie is not true (and) ridiculous. He's a nice man and loving father to his children," she said.

"What has been reported in the news by the international media ...very frustrating.

"They (are) waiting to blame the pilot. Speculation like this is killing the family," she added.

--

"Captain Zaharie is our friend's daddy. (our Melbourne's buddy).Our heart sank upon hearing the appalling news abt #MH370 .Thoughts n prayers goes out to the passengers on board also to their families," he tweeted,

The athlete's wife Tya Boo (@tyailyana) tweeted: "Pray for MH370 ...indeed so sad the pilot is my friend's daddy. Hope Aishah and family bersabar and banyak (patience and a lot of)."

As the search for MH370 entered its tenth day, Capt Zaharie's relatives posted a moving YouTube tribute to the man they love.

The three-minute video features a series of family photographs of Capt Zaharie and call it a "tribute to a man well-loved by many. The guy we all call Ari, Uncle Ari and Tok Manu Ari."

The video clip describes the pilot as "loving, reflective, generous, cool, sporting, intelligent, supportive, the list goes on and on …"

Well, one of the bigger terrorist threats has been that of dirty nuking a city. Fortunately, matériel, delivery, and effective dispersal have been their challenge.

Most of the stuff I've read/seen suggests that it's not just a challenge, but that actually building a dirty bomb that would kill significantly more people than a normal bomb is basically impossible -- if you disperse the radioactive material widely, then your large bomb that would kill 1000 people without radioactives kills 1000 plus a few more people than would otherwise be expected die from cancer later, and the threat to humans basically disappears the next time it rains. If you don't, then hazmat crews pick up the chunks of crud, and your bomb that would kill 500 people without radioactives still kills 500 people and maybe a couple of unlucky saps who actually get hit with radioactive shrapnel.

From the stuff I've read/seen, the only realistic additional threat from a dirty bomb compared to the equivalent normal bomb is media-induced panic.

Did Malaysian Airlines 370 disappear using SIA68 (another 777)?

Interesting theory. If MH370 got close enough, its primary return would merge with SQ86* and it would be, for all intents, invisible to radar as long as they stayed close. If they flew a little behind and below, SQ86 would not notice them.

Issue -- SQ86 would have been at cruise. Airliners at altitude cruise at very near the fastest speed they can go. For the 777, typical cruise is Mach .84. The max they could go is Mach .89, a difference of 22 knots at FL350. Could MH370 have caught SQ86 in time to not be seen by Indian radar, that being the first they would have encountered? Would he have been in range of China's OTH radars (which would show a merging contact if so.)

Note: on that flightradar.com screenshot, you see the speed listed as 400kts. This isn't airspeed, that's ground speed. Traveling basically to the west, both planes would probably be encountering headwinds, which generally flow west to east on the Earth. This is why ORD-LHR is usually well under 8 hours, and occasionally under 7, and LHR-ORD is over 8 hours, and occasionally over 9.

But, unlike many theories, it fits all the facts we know so far. MH370 was there, as was SQ86. Nobody is reporting an unidentified primary return entering India. There was a ping from MH370, possibly in the northern arc, which SQ86 travelled near.

Question 1: At the time of that last ping, was SQ86 on that arc identified by the satellite ping? If so, this becomes a stronger theory, and I'm tempted to say *much* stronger. If it was a hundred-plus miles away, this becomes much weaker.

Question 2: Did either of the pilots of MH370 do any formation flying in their careers, esp. in large aircraft (example, air-to-air refueling.) If so, that demonstrates the skill needed.

Question 3: Did the captain practice this on the simulators he had?

* Let's all use either the three letter abbreviations (MAS370/SIA68) or the two letters ones (MH370/SQ86).

This is a strange theory. Would one have been able at all to plan it this way? Unlikely: what if SIA68 was delayed?

Or is it that they were kind of astonished that they had made it so far without being detected, and then, "hey, look, another jet, let's hitch-hike"…?

If you click through saucysault's FlightAware link you get to the track log table for SIA68 which makes it much easier to pick off points. (For comparison, here's Flightaware's tracklog of the missing plane MAS370). I started getting all Hardy Boys on the track logs. But there's still no public information about the missing plane's location for the six hours between the last radar fix at 13:17 and the last satellite ping at ~19:13. FWIW, at 19:13 SIA 68 was estimated to be at 33.3997, 58.8358; that's 10 degrees south of the candidate MAS 370 positions. But that doesn't really disqualify the theory, perhaps MAS 370 had long since gone its own way after penetrating Indian airspace.

Truthfully, I think the "shadowing the other plane" theory is some Tom Clancy nonsense. So is the dirty bomb theory. Occam's Razor is usually right. A suicidal pilot, a mechanical failure, a hijacking gone wrong can explain all the things we know.

As long as investigators are still very intent on the northwest over-land route as a possibility I like the theory that they shadowed another plane, because they've really been focusing on that despite ample radar coverage making it seem like the route would be very unlikely without some other factor.

Question 1: At the time of that last ping, was SQ86 on that arc identified by the satellite ping?

So, no. To, reiterate Nelson's explanation, SIA68 was in Iran at the time of the last ping, 1000mi SW of the westermost edge of the "ping arc".

If the shadowing did take place, MAS370 would have to have broken off in India to reach the "ping arc" by 0011 UTC. Thus, it should have been picked up by radar within India and on China's southern border.
posted by pjenks at 8:49 AM on March 17, 2014


And it is improbably they would have found another northbound aircraft to mask with after leaving SIA68 as there were too many variables to ensure they would meet a scheduled aircraft at a planned time, although I guess they could try. It feel like I am looking for any shred of hope that the crew and passengers are safe somewhere.

Although, given that other A/C would have lights on, they could have jumped on an opportunity and followed a northbound that happened to pass close by.

And, yes, this is farfetched. Pretty much every, err…, nearfetched theory of what happened to MH370 has gone by the board. All that we have is farfetched, and that means either they went south and fell into the ocean after flying for some hours in a planned fashion, or they somehow went north.

Neither posit has much in the way of rationality in its favor. If you were just going to kill yourself and the plane, why bother flying all that way south? If you reject that, you need to figure out a way they go north, or you have to posit something where there wasn't human agency involved, or you invoke conspiracy, aliens, magic, or a combination.

The answer is going to be crazy, whatever it proves to be.

According to Flightaware, SIA68 was nineteen minutes delayed on departure (they were supposed to leave SIN at 12.40, they left at 12.59, MAS370 was supposed to leave at 12.35 and was delayed to 12.43). This would account for the forwards and backwards tracks across the Malacca Straight that intersected the planned route (red line) and delayed route (blue line) on the first image if MAS370 was specifically looking for SIA68. Still doesn't answer what happened after, though. The last image illustrates Nelson's point, albeit with some mapping/projection problems. (Not my images, btw, via reddit)

The flying south part makes more sense if you consider that it might have been on autopilot. If the goal of the evasive flying was to make sure the plane was never found, there was never evidence from the black boxes, and therefore insurance paid out to the family (a la the Fedex attack.) It's possible that the pilot deliberately or accidentally succumbed to hypoxia and the plane flew on as a ghost plane. There aren't many waypoints in the South Indian/Antarctic ocean. It'd be interesting to see if any of the existing ones result in a position on the arc if plotted from the last likely known waypoints.

We haven't heard a shred of motive that would suggest a reason for any of the crew to do that, though. A depressive fit, you could see coming on without much external cause and leading to the impulse to dive it into the water, but everything about this has suggested considerable forethought and planning.

I have zero idea what happened here, but I'm always fascinated by the Seconds from Disaster episodes where one little thing (slightly improper install of widget) lead to this and then to that and pilot error compounds the problem and on and on until Disaster.

Since the disappearance of MH370 is almost definitely purposeful, you have to wonder what small events led up to that decision. Why was someone so angry or distraught? A fluke of brain chemistry? Not enough attention as a child? Boyfriend/girlfriend broke up with them? Is it possible that if we could have changed one single thing, it would have averted this entire tragedy?

On a flight of 200+ people, there are surely at least one or two who Weren't Supposed to Be There Today (missed a previous flight, had to leave KL early due to family emergency, whatever). There were dozens of stories of people who were supposed to be in the Twin Towers when they fell, but had missed a bus or overslept or had their appointment cancelled.

I don't know whether the fact that each event in life is necessarily caused by another event makes life seem more or less random, if we can never know the causes.

This comment is intended to be more philosophical than actual speculation. My wishes are with the passengers, the crew, their families, and the SAR folks.

From roomthreeseventeen's link:

"But Malaysian Airlines CEO Ahmad Jauhari Yahya said, "We don't know when the ACARS was switched off," adding it could have been disabled at "any time" between when the ACARS said all was all right with the plane's health and the next half hour when it should have, but didn't, transmit again.

The transport minister, standing next to Mr. Ahmad on Monday, didn't respond to the CEO's new timeline. The transport minister's office earlier said it stood by his portrayal of the sequence of events.

The discrepancy didn't change the overall assessment that someone in the cockpit either intentionally, or under coercion, switched off the transponders, and possibly even the ACARS."

I've got to believe the US knows whether the plane went north or south. I don't have much of a basis for that, only my perhaps erroneous belief that the world makes more sense than this story has made so far. Under this scenario the authorities are not making that information public because until they have eyes on wreckage they must operate as if there is still a possibility that someone (either passengers or perpetrators) are alive and so certain information has to be held close to the chest.

If it really is the case that nobody has the first clue whether a 777 with hundreds on board flew for thousands of miles either north or south after flying directly over Malaysia, well, stop the ride because I want to get off.

But he does provide some further analysis, in his comments section, which considers the new data (search for comment starting "Diego and all who have commented") - in summary: fire disables ACARS unknown to crew, all is felt normal at final radio transmission, fire disables further comms systems, pilot takes action by turning SW towards runway at Langkawi, attempts to climb to 45,000 feet might have been a last ditch to oxygen starve fire, crew overcome by smoke, plane continues on autopilot heading south until fuel exhaustion.

The information at roomthreeseventeen's link seems to mitigate the captain/first officer's involvement.

But whatever happened happened between the sign-off at 1:17AM and the transponder ceasing at 1:21AM with the plane changing course shortly thereafter.

Re Cell Phones: The above linked Air Traffic Management article cites this final report of a UPS Boeing 747 freighter which crashed in 2010 after a (lithium battery) fire in its cargo hold. In that case the fire took about two minutes to start to disable flight systems and fill the cockpit with smoke to the point where the crew could not see the controls. After a couple of more it seems to have affected the Captains's oxygen supply so that he lost unconscious. Given the potential speed at which a really nasty cargo hold fire could spread it is possible that MH370 passengers never had the opportunity to see whether they could make a call or not.

Deliberate or accidental decompression could have killed the fire, and also explain the altitude changes. The turn back towards Malaysia would be a logical reaction for a plane in distress, and the transponder going out and the ACARS going off could have been the pilots pulling circuit breakers to fight a fire, and possibly some error in the cockpit emergency oxygen could lead to a decompressed plane flying onwards. If it wasn't for the multiple direction changes in the Malacca Strait, I absolutely would think it would be the leading theory. But those direction changes... there's no reason for a pilot fighting a fire to have put in those headings. They say pretty clearly there was active human intervention.
posted by tavella at 5:50 PM on March 17, 2014


The hard part about any fire theory is the plane flew one for at least an hour, closer to six hours if you believe the satellite pings.

So, you want to posit fire? Fine, but you need to explain why a fire let that plane keep flying that long, when historically, unchecked fire brings down planes fast.

1) A lithium battery fire does not require an oxygen supply to burn.
2) A pilot who climbed the plane to put out a fire instead of descending immediately to land is totally 100% crazy. I'm more willing to believe the absurd "radar shadowing" thing than an intentional climb due to fire.

But I understand the point that nothing about this incident makes much sense.

Landing soonest: The airport at Kota Bharu was closed at night. The airport at Kuala Terengganu (on the flight path) was probably also closed but its runway ends at the beach so potentially better.

Flying over the Malay peninsula after fire is put out at high altitude (although people have been saying that radar is very unreliable in determining altitude) to land at airport with best emergency equipment... KL. Doesn't explain the zig-zag, loathe to attribute it to pilot disorientation.
posted by TWinbrook8 at 6:29 PM on March 17, 2014


I was talking about a regular fire here, not a lithium-ion battery one -- there's plenty of ways fires can get started on planes without lithium. And the point about decompression was that a normal fire could have started and then gone out, in theory, without fatally compromising the air frame. Though it's a fair point about the altitude changes -- a pilot would be more likely to try to ditch in the water than do that.

However, as I said, all theorizing about fires (or simply decompression on its own) hits the wall of the course changes. If it had merely turned once and disappeared off into the southern Indian Ocean, people would be thinking Helios 522. In fact, that would have been a more effective way of covering up a suicide -- if that's what it really was, the author of the incident may have overthought themselves.

So this is the latest thing from 5 minutes ago - whoever changed the course of the plane did so by keying in the waypoint, not by manual control - but I don't think that tells us anything more than the fact that the plane was flying towards the waypoint anyway. I think it's a circular argument.

From that article:

Whoever changed the plane’s course would have had to be familiar with Boeing aircraft, though not necessarily the 777 — the type of plane that disappeared. American officials and aviation experts said it was far-fetched to believe that a passenger could have reprogrammed the Flight Management System.

It really doesn't seem that far-fetched, all someone needs is a list of commands to punch in and the knowledge of how to punch them in, which they could get any number of ways. Maybe it was someone who only knew the bare minimum of how to do that and they punched in the wrong numbers? That could explain the zigzagging.

It was certainly looking bad for one or both of the pilots but the shadow of doubt over their guilt came yesterday:

^ "Alright, good night" comes around about half an hour after take off, shortly after the plane reaches cruising altitude [...] Sounds like pilot/co-pilot pee-break time.

^ ACARS last transmission at 1.07am but it was NOT switched off at that time.


It's now entirely possible a rogue passenger (or 5) gained early control of the cockpit.

This guy has a long write up with an analysis of why he thinks it's an in-flight firem, which accounts for the turning off of electronics as well as the turning of the airline. Mind you, I'm of the mind that it was an in-flight problem and not a hijacking/crazed pilot/otherwise. Nothing the Malysian government, airline, or officials has done has left me thinking they have any idea what they're doing, and they keep changing their story on a daily basis.

I don't blame people for still focusing on the pilot or looking for evidence of hijacking. I think we humans are prone to wanting there to be a reason and someone to blame in a situation like this. If you can point the finger at an individual who screwed up it's almost a sort of comfort, whereas the alternative involving a uncaring random universe doesn't offer the comfort of assigning blame or being tractable.

Maslow, my understanding is that ARCARs (the mechanism that is supposed to report every thirty minutes and did so at 1.07 but not 1.37 as scheduled) reports everything currently entered in the Flight management system (the autopilot, basically). The five digit code for the waypoint (and there is NO way five random letters were entered that just happened to be two waypoints nearby) were entered into FMS before the 1.07 ARCARS transmission.
If there was some sort of crisis/fire there would be no reason to enter waypoint so far off the scheduled flight path at least fifteen minutes before they were to take effect while the pilot continued to fly normally. The co-pilot also would have not said a calm "good night" in the face of a crisis. The suddenly turn westward over the peninsula was planned at least fifteen minutes before it happened according to the information released today.

I spent way too long reading about the interface to the FMS over the last couple of days. Suffice to say that the waypoint could have been entered in immediately before the turn began (not 15 minutes before) and the system is easy enough for a trained non-pilot to use.

The FMS does normally broadcast the flight plan via ACARS but like everything else this can easily be disabled. Today's info that the FMS was used for the very first turn could easily be derived from radar info since the FMS makes extremely precise, steady turns.

The FMS does normally broadcast the flight plan via ACARS but like everything else this can easily be disabled.

So either ACARS was disabled from broadcasting the FMS (which would not be normal procedure) at least fifteen minutes before the turn, or the ACARS broadcasted the FMS including the sharp turn fifteen minutes later. Either way, it sounds deliberately planned rather than a reaction to something like a fire.

From the article: Flight 370’s Flight Management System reported its status to the Acars, which in turn transmitted information back to a maintenance base, according to an American official. This shows that the reprogramming happened before Acars stopped working. Unnamed sources, but clearly stating the change in the FMS was transmitted via ARCARS at the 1.07 transmission. Why this wasn't immediately released ten days ago is another mystery.

I have no idea what the article is actually saying, honestly. If they have a flight plan from the FMS, does it actually match up to the data from radar and satellite? Or are they just saying a waypoint was added to the flight plan before ACARS shutoff but it's not on the path that the flight later took.

From the gusrdisns live up date site

A search operation has exposed a “deep-seated reluctance to share military information” experts have told the Wall Street Journal.

While small aircraft could fly low enough to avoid radar, it would be almost impossible for a Boeing 777-200 to dodge an air-defense system operating effectively, according to Keith Hayward, head of research at the U.K.’s Royal Aeronautical Society.

“You’d have to fly well below 100 meters, and the 777 is not designed to fly that low,” Mr. Hayward said. “You would exceed the aircraft’s stress levels.”

Ground-based military radar typically has a range of up to 250 miles, its extent being limited by the Earth’s curvature, Mr. Hayward said. That should have put Flight 370 within the range of Thai military radar, and possibly also Indonesian and Indian radar, as it flew west of Malaysia. However, all three of those countries have said they saw no sign of the missing plane.

Malaysia’s neighbors “would be as helpful as they could be without giving away anything about their own weaknesses,” [Tim] Huxley [executive director of the International Institute of Strategic Studies-Asia] said.

Defense Minister Hishammuddin Hussein said last week that Malaysia was divulging unprecedented national security information and invited other nations to overcome their reluctance and help find the plane.

India and China, which Flight 370 would have crossed if it moved along the northern corridor plotted by investigators, have more capable air-defense networks than Malaysia and its neighbors.

However, Indian officials gave conflicting comments Monday about whether radar systems on the Andaman and Nicobar Islands were operational at the time that Flight 370 may have passed.

China has advanced monitoring capabilities, including the Ganbala radar station in Tibet. At an altitude of about three miles above sea level, the station is the highest manually controlled radar station in the world.

Malaysia has asked Beijing for radar data, but it wasn’t clear whether China had complied with the request. Hong Lei, a Chinese foreign ministry spokesman, said Malaysia had made certain requests for information but he didn’t elaborate.

Another conspiracy theory (highly speculative) is that if the plane *did* land somewhere, Diego Garcia (the US/UK military base in the Indian Ocean) is one of the more plausible destinations due being purely military and capable of keeping the event (radar blips and landing itself) under wraps. Why the plane would have diverted to the military atoll on the other hand, who knows? Was it carrying cargo of interest? Were the 20 Freescale Semiconductor employees part of the reason? Was there intent on giving China more reason to increase their presence in and around Malaysia? Or was the plane instead intended to be used as a weapon against the atoll, was shot down, and has now become a diplomacy nightmare as the U.S. scrambles to plant its debris far away from the actual crash site?

Like most conspiracy theories, they're likely far off from the reality and better suited for a Tom Clancy novel. But if all indicators point towards the plane trying to land somewhere else...it seems like a plausible destination if the right reasons are at play.

Then it was incompetent hijackers, who were competent enough to vanish without a trace but not competent enough to read their fuel gauge correctly? Or pilots in a joint suicide pact with an Agatha Christie twist? Or ...?

But I'm coming back around to my initial feeling, that it was just a catastrophic fire / decompression / whatever, with the autopilots carrying out the last scrambled commands to the best of their abilities as the airplane flew deep into the open ocean before running out of gas.

"It really doesn't seem that far-fetched, all someone needs is a list of commands to punch in and the knowledge of how to punch them in, which they could get any number of ways."

Including looking at the flight manuals or just spinning the dial marked "heading." ;) People act as if these flight management systems are so incredibly complex that no layperson could possibly operate them. They're really not that complicated at their most basic level. They, like airplanes in general, are actually incredibly simple at the highest level. (Note: I am not in any way saying I would like to attempt to land a 777, thanks, just that anybody here is capable of giving a 777's flight director an altitude, heading, and speed with no training whatsoever if it is already engaged.

At one point I had theories, but I'm having fewer and fewer as days go by. The crazy Diego Garcia theory that has been going around is obviously completely shot to hell by the arcs, but those are themselves a bit..unreliable at best.

It could be an incompetent hijacking where the hijackers' organization is too embarrassed to claim responsibility. Like the hijackers were basically untrained and only knew how to put numbers in the autopilot and then point the plane at a target once the autopilot took them there, but were either given the wrong autopilot codes or punched them in wrong and then basically had no idea how to correct their course and the plane just flew around until it was out of fuel.

Or perhaps hijackers threatened to blow up the plane if the pilots didn't acquiesce and the pilots decided to take it out over open ocean where nobody on the ground below would be hurt if the hijackers did that.

The Freescale angle has led to some seriously silly conspiracy theories, including actively anti-Semitic ones. It's a dead end. It is unsurprising that a large company would have a group of members on one flight. It is unclear how massive, mysterious, plane-disappearance caper with global attention would be the best way to resolve what dispute would have occurred. If this was a business dispute, then we're talking about a company with less than half the revenue of, say, Nikon. If this was a national security dispute, then why wouldn't the Powers That Be have done this kind of thing to Snowden, Manning, et al.? Life is not Snakes On A Plane - not even mean and nasty people resolve disputes through the most bizarre, showiest means possible.

That Goodfellow article saying it's a simple electrical fire sure is making the rounds today. It mostly proves one point: you can always spot the pilot in a discussion because he's the one telling you he's a pilot. (Source: I'm a pilot.)

As noted above, his theory completely fails to explain the airway maneuvers west of Malaysia, "GIVAL to IGREX". If there was an emergency and they pilot was messing around with the flight plan, he'd be punching in "direct to airport". There's even a special button just for that purpose, at least on the small navigation computers I'm familiar with. It also doesn't satisfactorily explain the satellite-derived location six hours later.

I've been racking my brains for days trying to come up with some other explanation for that routing. Maybe a stressed pilot just punched in some airway whose name he remembered and it ended up generating that route? Very unlikely, but not impossible. Then again the public doesn't really even know if those waypoints were truly on the route; the information that's been leaked to us is unreliable. And some sort of fire is definitely possible. And once you posit that, all sorts of random aircraft paths become plausible. Planes with no control fly in weird ways.

Even if the arcs from the satellite pings are off, I don't think they'd be that far off. Additionally, they describe the low flying jet as being very noisy, indicating it was likely under climbing power. If they had been flying at low altitude for much time at all, they'd be out of gas by the time of that sighting. There are daily 777s to many destinations from the Maldives, including to points south(ish), so it seems highly unlikely this sighting is in any way related.

Diego Garcia runway found in Captain Zaharie's flight simulator

This feels iffy to me, because why wouldn't he practice Diego Garcia and all sorts of other runways around there if he flies that part of the world all the time for his job and has an interest in home flight sims?

Does anyone know if it's plausible that a fire could partially disable the aircraft yet allow it to keep flying for seven more hours?

He can't see any way this makes sense without a deliberate act by the pilot (he's pretty sure it's not the co-pilot).

With all due respect to the passengers and crew and their families who are obviously suffering, this is just fractally weird. Seriously, just look at any one part of this whole situation, and it just becomes weirder.

I wonder how much of the apparent weirdness is coming from a Fukishima-style approach to news coverage, people somewhere saving face (which, given the albeit tenuous Diego Garcia thing, could very well be US officials saving face, I don't mean to make stereotypical obvservations about Asian cultures), or both.

It seems to me, some of it based on actual evidence of how the Malaysian government has been responding to this, that someone somewhere knows a lot more than they're telling. I'd bet on that someone being the US government, frankly. I'm not saying conspiracy theory, I'm saying "Well we know exactly where it is but if we said so we'd be exposing all sorts of intelligence assets."

Not a good reason when the lives of nearly 300 people are at stake, obviously.

All that being said I know fuckall about how planes work, but based on the amazing commentary above (many thanks especially to divabat and eriko, among others) it seems like there's just no way in hell that someone didn't plot that route.

I'd also like to echo the call for a plausible scenario in which a fire knocks out all comms while allowing the plane to continue flying for several hours. (Or have I missed that?)

What a terrible, terrible tragedy.

The elephant in the room with Diego Garcia is that it's not just a runway on an empty island, it's one of the more important American military bases in the region. It seems unlikely an aircraft with a disabled transponder would be able to approach without them taking self-defense measures.

I'd question, though, the willingness of American commanders to give the order to shoot down an obviously civilian plane that's making a landing approach (assuming that's what was being done) even if it's radio-silent.

On the other hand, spinning out the DG hypothesis further: allowing them to land and then remaining totally silent about it lends credence to the There Was Something Important on the plane theory.

The Diego Garcia thing is a total red herring. It's a fantasy airport for pilots, an interesting place in the middle of nowhere you'll never get to land. I mean I've stared at the overhead imagery before thinking "wouldn't it be cool if I could land there?" It's a natural thing to play around with if you're a pilot geek with a simulator.

I think that it would absolutely be shot down if it was headed straight towards the fuel dump and wasn't stopping, but that's neither here nor there.

I found Ken Cubbin's "Cockpit doors, a false sense of security?" interesting article in light of MH370 speculation. He points out that the doors need to be opened about 20 times per flight on average. Doing this in a secure manner really needs a double "air lock" type door or the sort used by El-Al. But these are costly so manufactures and airlines come up with their own ad-hoc policies. While these procedures may be confidential they must also be widely circulated - so it can be assumed they are not that secret. There are probably also some quite predictable patterns of when a door is likely to be opened.

Maybe I'm missing this, but as far as I know, we still haven't seen the ping arcs ("satellite corridors", which is rather misleading terminology) for the rest of the flight.

We know from the last ping that the plane was (probably, with an unspecified uncertainty radius) on one of two arcs - a northern arc that would have had it fly through India/China/Pakistan/Myanmar, or a southern arc that is open ocean but approaching Australia. The gap between the arcs corresponds to Malaysian/Thai radar coverage, and the rest of the circle is out of range / covered by other satellites. So far so good, yes?

But the ACARS pings happen about once an hour (?), and I don't see similar arcs for the previous pings. Why not?

(a) I'm an idiot and failed reading comprehension. (P->100%, but may not be the right answer here.)

(b) Someone is sitting on them but hasn't released them because (i) it exposes some capability that they'd rather not, or (ii) keep out of the big boys room, you nosy amateurs.

(c) They don't exist - the system purges all but the last contact in the interests of disk space. This might have made sense in the 1980s I guess but surely such a policy would have been revised by now?

in the Hollywood movie version, Denzell Washington (or whoever) trusts his gut and lets the airplane land (or fly past) ... or perhaps Sandra Bullock shows up at the last possible second with proof that there is no harm intended, it is in fact an airplane in distress.

Had flight MH370 appeared out of the blue on approach to Diego Garcia after its overnight off-course sojourn it would not be the plane in distress, but any surviving passengers and those closest to them; and we'd all watch helpless while it was fired on.

As a slight aside, I'm confused about how the Malaysian military (and possibly other SE Asian countries' militaries) allowed such a large unidentified object to pass through their airspace apparently with no reaction from them. Is this right? If I correctly understand everything I've read, Malaysian military radar picked up an unidentified object flying through their airspace shortly after MH 370 disappeared, and apparently didn't do anything about it. Thailand too? It seems first of all bizarre to pay for military radar if you're not going to act on the data that it throws up, and if you're going to allow unidentified aircraft to enter your airspace anyway. It also strikes me as irresponsible, once MH 370 disappeared, not to have coordinated better between their civilian and military radar. Presumably had Malaysia done this, it could have stopped the plane as it was doubling back across their country westwards. Is this right?

You know, the real question here is still... why Gival to Vampi? It makes no sense under any scenario.

If it's a suicide, why wouldn't the pilot fly straight out into the Indian Ocean? He's already flying over Malaysia so he can't be *that* concerned about radar, and you could keep the same heading and only pass over some small islands. And even if turning up the Malacca Straight was some plan to avoid radar -- you can just go from Gival to Igrex and it will shoot you up the straits. Vampi actually brings you *closer* to likely radar, putting you just off the Thai coast.

Same if the pilot is heading north as a hijacking -- why not stay Gival to Igrex? Why buzz the Thai coast? It really does look more like a confused wandering than a logical plan, yet they seem pretty certain by the pattern of turns that it's a deliberately set course, and yet it's hard to see a pilot being so disoriented that they are putting illogical points in, and yet get ones that plot a course close together. Especially if there's a flat out 'return to airport' option.

I don't know if it was ever officially stated, but I think I read somewhere that the gap could also correspond to where the signal would have also been picked up by the next satellite to the east. Note that Thai radar data wasn't shared until today.

It would be interesting to know the error range of the satellite transmission angle since this is a novel (and probably complex) way of calculating plane location. For instance, was the calculation made by calculating round-trip signal time? Was the data transmission only one-way? Or was the plane's timestamp compared to the satellite's clock sort of like a reverse GPS? If the latter, you would need to know the accuracy of the timestamp from the plane. I suppose there could even be some relativity effects on the satellite clock that might not have ever been relevant before if it wasn't designed for this type of location calculation.

Well, you've got at least China and the US with assets in the region, I wouldn't be surprised if Malaysia thought the unidentified object was a military plane belonging to one of those countries doing a flyover. I'd imagine countries probably see that kind of thing all the time and it would seem pointless to even bother attempting to hail it.

If it's a suicide, why wouldn't the pilot fly straight out into the Indian Ocean?

If we assume for the moment that a) it's pilot suicide, and b) that the copilot was complicit or subdued, and c) that the passengers and rest of the crew were somehow subdued (someone mentioned the sudden climb + depressurization?), then this flight pattern actually does make sense.

Some people who commit suicides don't want to look like they've killed themselves--for honour, family memory, insurance/benefits, whatever. Subdue the rest of the plane (somehow), turn all comms off, make some apparently purposeful course changes, fly past the point of no return.

You've now left behind a mystery, and an honourable death. You won't be vilified after death as that guy who killed nearly three hundred people.

stopgap: Agreed, but again the negative PR of not doing anything at all?

For the record I don't think there's a US coverup of the "we blew it up" variety. If the Diego Garcia angle turns out to be actually relevant, then I might believe a coverup of a "we needed something on that plane desperately" variety.

RedOrGreen: I'd rather believe the same thing. But. Imagine this: you're the commander of the base, woken up in the middle of the night, told about this thing incoming. You give the order. Shortly thereafter you get a comminque stating to be on the lookout for such a plane because it's a missing civilian transport. After saying "oh fuck" a lot, you're probably going to call your superior and say "We may have a situation." Coverup seems likely from there, and it would be again impossible from a US standpoint to refuse to help out with this kind of humanitarian mission. There's could also be a left hand/right hand thing going on, or the TS/SCI thing preventing the left knowing what the right is doing.

jason_steakums, I get what you're saying, but world opinion being what it is nobody's going to pay attention to the 'collision course' bit, you know?

Bear in mind I'm obviously just wild-ass guessing like everyone here, just contemplating the consequences if X is true.

I think in all likelihood the most reasonable explanation is a hijacking gone wrong. Hijacker(s) overcome the pilots enough to kill comms, say "Take us to Wherever" and the pilots make it look like they're punching in the location while actually setting a course out to sea.

I can't think of anything--even as little plausible as that one is--that makes sense otherwise.

If it had been shot down by anyone in the area capable of doing so, would there be reasons they'd want to hide it? Say, fear that any involved may take retaliatory actions after the death of so many of their citizens on board?

Being shot down and then kept quiet would explain a lot of this, but what reason would any country have to do that?

On preview though, fffm's hijack and ditch theory makes even more sense. But still, I wonder.

Yeah, this is my vote for most reasonable theory, too. Doesn't require the pilot or copilot's disposition to wildly change from what people knew of them before, hijackers could physically prevent passengers from trying to use phones even if they did work or prevent it with the threat of a bomb or something else that the passengers couldn't fight back against, and if the hijackers required the pilots to make the plane do anything and the pilots realize the lives of everyone on board are already a lost cause, there's nothing the hijackers could do about it if the pilots entered in a course that took them way over water where they couldn't do any further damage.

If we assume for the moment that a) it's pilot suicide, and b) that the copilot was complicit or subdued, and c) that the passengers and rest of the crew were somehow subdued (someone mentioned the sudden climb + depressurization?), then this flight pattern actually does make sense.

Some people who commit suicides don't want to look like they've killed themselves--for honour, family memory, insurance/benefits, whatever. Subdue the rest of the plane (somehow), turn all comms off, make some apparently purposeful course changes, fly past the point of no return.

You've now left behind a mystery, and an honourable death. You won't be vilified after death as that guy who killed nearly three hundred people.


The problem is, the course changes would make it *less* likely that it would be taken as a suicide. If all we had was a sequence of "comms go out, plane turns back towards Malaysia but then continues flying in a straight line out into the Indian Ocean", the overwhelming assumption from everyone would be that something had gone wrong that had taken out the comms, that the pilots had turned back to try for an emergency landing, but were overcome by hypoxia or smoke and the plane flew on as a ghost plane. Because variants of that have happened before. And experienced pilots would know that; they'd know that a plane under apparent conscious control would look far more suspicious than a simple, believable one turn story.

If they were concerned that a single track into the ocean would leave it potentially findable, you could easily program a slight turn in the middle of the Indian Ocean, far away from any likely radars, as opposed to the Malacca Straits, with the potential for multiple country's radar detecting it. And if they were concerned about picking up a jet escort that might be able to identify the crash spot, they had already flown at a very detectable altitude over Malaysia. Why all but taunt the air forces of multiple other countries to notice you?

Honestly, it almost does make the hijacking/pilots attempting to attract attention storyline believable. Though that of course brings up questions: if they went north, how could they possibly have escaped notice to end up in Central Asia, if the pilots weren't helping? And if it went south -- you'd think at some point the hijackers would try to take direct control and either crash it or turn it around, not have it sail on for so many hours to nearly the Antarctic Ocean.

As someone said above, it's fractally weird.

So very weird indeed. My hardest problem is grasping that no one anywhere in the world seems to know anything about what really happened. And then I come back to the fact that the world is HUGE, and it is apparently even huge enough to hide from all of its residents evidence of 300 souls (living or dead), and a jumbo jet (in tact or in thousands of pieces, some of which would float and presumably be seen by someone). With all of the information available to us today -- and available immediately and exponentially -- it's just really hard to accept that there is no information about what occurred, or at least that we don't have the equation that would, by some sort of arithmetic, make sense of what we do know.

Yes, that's my point exactly. The family gets to go on living thinking their son died valiantly, the pilot committing suicide knows that his name won't be spat on.

Again though, I don't think pilot suicide makes any sense, unless we're talking a severe psychotic break. The last thing, when you're suicidal, is wanting to draw out your death; I think a suicidal pilot would drop the nose, crank the engines, and go straight down.

it's just really hard to accept that there is no information about what occurred, or at least that we don't have the equation that would, by some sort of arithmetic, make sense of what we do know.

This is why I think there is more known than we are being told. Most especially, I strongly suspect that the US government has pictures that would at least flesh out the story, but can't/won't release them for fear of revealing certain surveillance capabilities. I'm not getting all conspiracy theory here; I'm just saying that the US has eyes in the sky that see a lot and it would be surprising if they hadn't picked anything up.

Here's the interesting thing about the Diego Garcia connection:

Diego Garcia is in the Chagos Islands, which are owned by the British, but the U.S. has a significant naval base there. British law has extremely strict rules about the environment in the area--so strict that when the base was built in the 1970's, the Chagos Island natives were run off--sorry, 'relocated'--to the Seychelles area because they could not be trusted with the protection of what has been considered by some the most pristine waters in the world. Obviously, this rankled the natives, who have been protesting for years their right to inhabit the island.

Just a few days ago, the British press broke the story that the U.S. Diego Garcia Naval Base has been dumping human waste and sewage into those waters for years, polluting the waters To the point where the coral reef is dying. Though this just came out in the press, apparently the British Government has known about the pollution issue since April of last year.

All of this is almost certainly unrelated to the missing jet, of course. I seriously doubt there is any kind of Eco-terrorism going on, for example.

But...with the revelations coming out now about this pollution and cover-up, it certainly seems like a PR nightmare if, on top of all that, this same naval base shot down an unarmed, non-military passenger jet with 239 innocent people on board, so I figured it was worth mentioning.

A plane ultimately left on autopilot for six hours heading somewhere very remote and far away.

Can someone remind me why we're talking about Diego Garcia again? It's 1600nm from the last known plane radar fix and a hell of a long way further from the Inmarsat ring where the plane is believed to have last been seen. I'll say it again; finding Diego Garcia in a pilot's simulator is in no way surprising. I guess it's an interesting place given how it's such a secret secure military base, not to mention connected to the US torture program, but there's no meaingful evidence it has anything to do with MH 370 and a lot against it.

I share RedOrGreen's desire for more information about Inmarsat-derived location hints from previous hours during the plane's flight. I've been watching this part of the story pretty closely and so far have seen nothing about it other than a lot of people asking. Hopefully the relevant search teams at least have access to the info. My guess is the only reason the one Inmarsat location got out was that the company was frustrated the Malaysian government was ignoring them and had leaked it themselves to the media (WSJ?) already.

This is the only plausible theory I've heard or read yet.

Except they *did not* head to the closest runway able to handle a 777. If the flew to Langkawi, they passed, by my count, 7 runways 6500' or longer, and the 2nd closest to their location when they made the turn was Sultan Mahmud Airport in Kuala Teenngganu, with an 11,400' runway.

IF they were on fire and they were trying to divert, they manually programmed their FMC a route that would keep them away from airports, instead of going to the FMC, hitting the AIRP button, which brings up a list of nearby *safe to land at for a 777* airports, then picking one of the closest 2 and selecting the bottom right function button, which, on that page, is labeled DIVERT NOW.

Seriously. ANY trained 777 pilot knows how to get a divert going. It's right there in the FMC. It would take *far longer* to program in the route they actually flew that to select WMKC or WMKC on the FMC and hit "DIVERT NOW"

No. It's not only not a plausible theory, it posits the absolute stupidest behavior by a set of trained pilots who are required to rehearse this procedure in simulators repeatedly. Suddenly, they forgot how to call up the diversion planning menu and went and typed in a route of five character waypoint IDs?

Right now some pilot friends of mine are having a heated debate about the details of what electronics would be working and what airport they might have diverted to etc on f'book. I guess the part they and, by extension I, found plausible is the fire/ emergency and that the pilots tried stuff, it failed and the plane crashed. All the hijacking and conspiracy theories seem insane.

There is also other not-officially-verified information that points towards a landing on land.

I think it's generally easier to wrap one's mind around an accident (however complex) vs. a precisely carried out hijacking. That's why many people believe it must have crashed in the ocean.

Some good analysis of the satellite angle calculations here. There is two-way communication, but it sounds like there are a lot of assumptions that go into the calculations, so I don't know how accurate they really are. The arcs are likely calculated based on either the delay between the satellite sending a ping and receiving a response, or the power level of the transmission. There is no discussion of any lag or processing time on the plane, which could lead to very different angle estimates. It also sounds like a banking plane could alter the perceived transmission power between antennas. I would interpret the arcs as more of a maximum distance from the satellite rather than a likely position. Again, I would be curious to see the intermediate ping calculations.

A follow-up post gives more timing detail. The plane is given a specific time slot to reply in, and the distance and speed calculations are based on delay and Doppler shift. So I think I have to retract my suggestion that the arc is more of a maximum distance.

Apparently it should be possible to reconstruct the intermediate ping arcs from the AMSA/NTSB southern search data. This would allow plotting the arcs on the northern route to test possible route hypotheses.
posted by stopgap at 4:28 PM on March 18, 2014


Ah, so they're using something analogous to GSM's timing advance field to derive the distance from the satellite. That should give a range accurate to within a few tens of kilometers at most (more likely closer to 1-2km), otherwise the terminals would be trampling all over each other when transmitting. Not terribly surprising it is logged, either. It's useful information to have for troubleshooting. It would also probably be relatively difficult to spoof that value, since it is measured by the base station (in this case the satellite), which then asks the terminal to transmit a bit earlier or later than it normally would.

Since the arcs are a mirror image, did anyone see a recalculation for the northern corridor?
Haven't read any official statement, but it seems like JORN was not in use. 3.200 km would be close to the maximum reach of radar 2 anyway, which does not cover the exact search area. What other info do you presume went into the calculations of the new search site?
posted by travelwithcats at 4:36 PM on March 18, 2014


It sounds like the assumptions for the southern search area were constant speed and heading, consistent with all (unreleased) intermediate ping arcs. This yielded only two possible southern flight paths. I don't know what their point of origin is — last known radar position?

So anything else than the inferred arcs? The speed can be calculated based on the distance between two arcs.

The speed can be calculated based on the distance between two arcs.

Right, but I think you need a point of origin to distribute the arcs uniformly. Since the two flight paths converge, maybe plotting them as great circles would give a second convergence point to use as the investigators' assumed point of origin.

I wonder if they are also considering waypoints. There's very few in that part of the ocean, and if you assume they went from Igrex to Rerab, the southernmost, it looks like you end up where they are searching on the sort of flight path shown. Not sure why there would be two, though.

posted by Mitheral at 5:56 PM on March 18, 2014


When you're talking about a search area comprising such a significant area of the Earth, the difference between a Beaver or Twin Otter and a 777 isn't so great. It's easy to spot runways where a 777 can obvioiusly and safely land from satellite views, because runways are very obviously manmade linear features. The plane itself, especially if broken up, but really even in flight, is much harder to spot.

I can understand why if anyone does have hard evidence they might withhold it because the ability to ferret such a small object out of a globe of surveillance data would suggest an existential threat to almost every other similar entity on Earth.

From the NBC article: "The change in direction was made at least 12 minutes before co-pilot Fariq Abdul Hamid said "All right, good night," to controllers on the ground, the sources said.

The revelation further indicates that the aircraft's mysterious turnaround was planned and executed in the cockpit before controllers lost contact with Flight 370. But it doesn't necessarily indicate an ulterior motive.

"Some pilots program an alternate flight plan in the event of an emergency," cautioned Greg Feith, a former National Transportation Safety Board crash investigator and NBC News analyst.

Hijacker(s) overcome the pilots enough to kill comms, say "Take us to Wherever" and the pilots make it look like they're punching in the location while actually setting a course out to sea.

I agree with this. My thoughts: hijacker breaches the cockpit, gets pilots to switch off communication devices. Says - "take me to x location" and the pilots program the waypoints - hijacker maybe none the wiser that they've just put in random locations. Maybe the pilot was trying to signal by the unusual selection of waypoints that they was under distress (if he was thinking they wouldn't make it, but that radars or satellites would show where they went). I read in one of the articles linked upthread that the climb to 45,000 feet followed by the uneven drop is consistent with a struggle in the cockpit, so maybe the pilots also tried to fight back. I also think that the plane flying for hours afterward would be more likely due to everyone being unconscious, like the Helios flight. So maybe during the struggle, something happened that caused the depressurization of the plane causing everyone to pass out and the plane to fly until it ran out of fuel.

Alternately, there were no hijackers, but it was one of the pilots and the other pilot tried to stop him, leading to roughly the same scenario above.

ARCARS and FMS are linked so information about things like weather, flight plans and engine performance can be shared both ways automatically. Why no alarm was raised over the changed flight plan at 1.07 might be one reason the Malay authorities did not release this information until yesterday's press conference.

hijacker breaches the cockpit, gets pilots to switch off communication devices. Says - "take me to x location" and the pilots program the waypoints - hijacker maybe none the wiser that they've just put in random locations.

It is kind of weird that the hijackers would know how to breach the flight deck in the first fifteen minutes of the flight while it was still climbing without raising the pilots' alarm (or the alarm of the people in business class that had access to plane phones I thought?) but not have a ready list of waypoints taken off skyvector and would just trust the pilots to take them there. And why would the pilots disobey, aren't they supposed to follow the hijacker's orders? It would also mean the hijackers were on the flight deck when the co-pilot said "good night" to ATC instead of the innocuously-sounding code-word for distress he could have used.

I suspect there is a lot of information we do not know that would change a lot of people's opinion of what happened. As it is, none of the three main theories fit all of the available information we have.

Acting Transport Minister Datuk Seri Hishammuddin Hussein yesterday conducted a closed-door briefing for Barisan Nasional backbenchers to update them on the status of the investigation into the disappearance of Malaysia Airlines flight MH370.

Speaking to reporters, he said the briefing...was meant to keep the parliamentarians in the loop on what had transpired so far.

The briefing, he said, was done at the parliamentarians’ request.

"This was not to share ideas or discuss sensitive issues about the investigation,” stressed Hishammuddin, who is also defence minister.

He said the parliamentarians had a responsibility to convey an accurate picture of the situation.

"The whole world is looking at us and it's important for us to be well-informed,” he said...

Hishammuddin said he was open to conducting a similar briefing for opposition members of parliament if they requested for one.

Meh, it's just more political games as usual for the ruling party. I mean next to throwing your opposition party leaders into jail on made up charges this is nothing. The level of BS produced by the leaders is pretty unbelievable, say only a few days ago the Deputy Home Minister insinuated that the Chinese and Indians were godless pagans who tolerate child rape. He was baited by a question on why the Malay community had a significantly higher rate of child rape cases, and his logic was that in reality the Chinese and Indians actually had higher rates, but because Islam doesn't allow child rape, only Malays report it to the police. seriously. He was being baited specifically because there was a case earlier where a 41 year old raped a 12 year old girl and once he was caught he immediately married her as a second wife (permissable under Islamic law) in order to try evade the rape charges.

I think what happened to MH370 is unprecedented. If anything good comes out of this I would expect all airlines to now have a direct line to the military: Malaysia has a squadron of SU-30's stationed on the East Coast at Gong Kedak, in future if an airliner ever drops off the radar by turning off its transponder they should immediately scramble an escort: the SU-30 can track an airliner 400km away, and they lost contact with MH370 140km from the coast, so it should have been more or less doable in this case, especially since it doubled back. Obviously the military isn't going to scramble jets on its own for any and every random radar return it gets, so this directive has to come from MAS itself saying they've lost contact with one of their jets and they need an escort / visual confirmation / short range VHF communication with it.

What amazing is how this plane is some sort of karmic reflector. People seeing the story they want to see, in the human interest, the international aspect, the terrorism claims. Because we know nothing about this situation, we prefer to project our own meaning on to the situation rather than accept we know nothing on it.

That's why I think it was a fire. We know nothing and it is the most parsimonious explanation. Planes catch on fire and when they do it is very bad. Commercial pilots don't hijack their own airplanes. Happened twice before this at most. Just so happened that one pilot did it three weeks ago in Europe. So that's what's fresh in CNN's mind.

I've never ever seen such rank speculation presented as news before, ever. But for CNN, it is lucrative. They are crushing in key demos and were up 100% in the ratings from before. Hell, I turned it on. I never turn on CNN.

That's not the case at all. If the pre-programmed divert were a planned turn back due to any early flight emergency "All right, good night" at least 12 minutes and at most 40 odd minutes after deciding to turn back is simply not the professional response to KL's ATC on (temporarily) departing its airspace.

A fire is unlikely the cause.

Lack of Useful Radar Exposes Defense Weakness explores the issues of radar coverage and the relucatance among countries in SE Asia to share such information.


Series of Errors by Malaysia Mounts, Complicating the Task of Finding Flight 370:

The radar blip that was Malaysia Airlines Flight 370 did a wide U-turn over the Gulf of Thailand and then began moving inexorably past at least three military radar arrays as it traversed northern Malaysia, even flying high over one of the country’s biggest cities before heading out over the Strait of Malacca.

Yet inside a Malaysian Air Force control room on the country’s west coast, where American-made F-18s and F-5 fighters stood at a high level of readiness for emergencies exactly like the one unfolding in the early morning of March 8, a four-person air defense radar crew did nothing about the unauthorized flight. “The watch team never noticed the blip,” said a person with detailed knowledge of the investigation into Flight 370. “It was as though the airspace was his.”

Why the "startlingly simple" Chris Goodfellow fire theory is wrong. [via Slate]
posted by kreestar at 4:38 AM on March 19, 2014


We may never know what happened, because we're not being told the truth.

Please point out what statements you believe to be untruthful.

What amazing is how this plane is some sort of karmic reflector.

Totally.

The fire theory is just a non-starter at this point though. Planes do not catch on fire and then fly for six hours (Especially FBW ones!). Pilots would never turn off the transponder in response to a fire [1]. Pilots do not program a set of diversion waypoints during a fire, and then calmly say "Good night" to the controller 20 minutes later. Pilots would never intentionally climb a plane that was on fire.

In the first few days after the incident, I agree that fire was totally the best guess (c.f. SR111), but not finding the wreckage near the point of last contact and receiving the satellite handshakes six hours later are just really incompatible with fire.

[1] The Boeing Quick Reference Handbook says in event of fire, pull power to any obviously smoking/burning devices, but the transponders are located in the EE bay where the pilots would never see them. It does not say start throwing breakers to everything. It does not say anything about removing power to busses, as the Goodfellow writeup describes, since in a FBW aircraft you need those electrical busses to keep the flight computers running. Shutting them down would be make the plane uncontrollable. I understand that in an emergency people can do weird things, but Goodfellow should at least be honest that shutting off the transponders makes no sense rather than suggesting that all crew actions fit together perfectly. Not to mention shutting down the radios without at least sending out a mayday? Definitely super weird, definitely not reasonable behavior you can wave away with "aviate, navigate, communicate".

MeFi's Own Rob Cockerham had some comparisons.

The piece (for those who have not read it, it scales down the relative sizes of the Indian Ocean and a 777 to convey how much ocean there is to search and how little target there is to search for) is nice, but even when he gets down to the graspable area -- like finding a pen in San Francisco, say -- he is still using areas that offer a lot of hiding places instead of smooth ocean. I think to get a more accurate comparison, you need a relatively homogenous search area to convey the idea. If my math is right, this is comparable to searching a football field for a stray eyelash.

Yes, the transponders could have caught fire. But those are sitting in the EE bay right next to every other piece of electronics that control the aircraft, including the flight computers. So you need to burn up the transponders and the radios and disable the crew, but keep the plane airworthy. That's the part that just seems so difficult. And someone had to program in these diversions, which on their own are inconsistent with a fire. I'm definitely not going to say it's impossible, but it's a big stretch.

Re: waypoints & sequence of events

At the press conference today there was the following opening statement:
"I am aware of speculation that additional waypoints were added to the aircraft’s flight routing. I can confirm that the aircraft flew on normal routing up until the waypoint IGARI. There is no additional waypoint on MH370’s documented flight plan, which depicts normal routing all the way to Beijing."

Later on, there was a question concerning waypoints. A reporter asked if radar data showed that the aircraft passed through at least two waypoints after the turn back. That question was dodged. Check out the video at 16:15 for that particular question.

The very next question: "There were reports today that the plane diverted course and went westwards before the pilot said goodnight. Can you confirm?" Authorities replied with "That's not correct". That question starts at 17:40 in the same video. The reporter was likely referring to CNN's report about the pre-programming of waypoints:
"On Tuesday, a law enforcement official told CNN that the aircraft's first major change of course -- an abrupt westward turn that took the plane off its route to China and back across the Malay Peninsula -- was almost certainly programmed by somebody in the cockpit.
The change was entered into the plane's system at least 12 minutes before a person in the cockpit, believed to be the co-pilot, signed off to air traffic controllers.
" Article was updated after the press conference.


At a previous press conference it was clarified that it is not clear when ACARS was disabled. The only thing that is known is the time frame: 1:07MYT (last proper ACARS transmission) - 1:37MYT (next scheduled ACARS transmission that did not come through).

Right, the operative issue are the reports that additional off-track waypoints were programmed prior to the last ACARS update at 1:07. That report is super critical, and I think it's hinted at by the Malaysian authorities confidence in a "deliberate" action.

If those are not true, then I am happy to retract my reticence towards the fire scenario. But I haven't seen any statements directly contradicting that. The plane doesn't have to fly the actual waypoints prior to the sign-off, they can be pre-programmed, ACARS relays that update to the ground at 1:07, the pilots sign off, the plane reaches IGARI, automatically turns towards to the diversion waypoints, and the transponder is then turned off. I'm not making that timeline up as a wild guess, that's the sum total of the reports I've seen.

Also note that the aircraft doesn't necessarily fly "through" the waypoints, it flies towards them and when it gets close enough it turns towards the next one, so I wouldn't place much weight on that.

Smoke inhalation. When Payne Stewart's plane decompressed it flew for hours, off course. If the people in the aircraft died or passed out from smoke inhalation, the plane could fly for hours by itself.

He does the handy videos of fixing things to Youtube. He oversees simulator training for the airline he works for. Once when I dropped by his place and he was flying something new, he had the plane's schematics spread out on his table; not something required but something he needed to know to make sure he and his passengers were as safe as possible. He's politically active.

This hits him hard. He can see no way but an intentional act. It's pretty awful.

kiltedtaco, what reports do you have in mind?

I think it's possible to interpret the official statements one way or another, but the press blows stuff up and then that in turn is rephrased and spread. There is a lot of wrong info floating around.
There are testimonies that I am more likely to believe, like that Vietnamese ATC "frantically" tried to establish contact on 121.5 for example. Other things are repeated and repeated although the sources are not verified. I'm sure the Malaysian authorities have had grounds to label it "deliberate" action. Were those grounds interpretations of raw data that is verified, did this interpretations change in the mean time or was it a political reason to enable them to classify it under Section 130C of their penal code, making it an offense relating to terrorism?

I mean we can talk about the "unnamed officials". What do you guy think about those?

Anyway, if someone wants to read more into it: Apparently this woman's banner said: "We are against the Malaysian government for hiding the truth and delaying the rescue. Release our families unconditionally!" As mentioned upthread, there were some rough scenes prior to the press conference today.

In the interest of supplementing the discussion with verifiable facts, I filtered this Wikipedia list to incidents that are specifically the pilot crashing their own commercial scheduled flight. These include Japan Airlines Flight 350 in 1982, EgyptAir 990 in 1990, Royal Air Maroc 630 in 1994, SilkAir 185 in 1997, and LAM 470 in 2013. There may be others, I haven't done a full survey.

Yes, pilots crashing their own planes is uncommon. No, it's not unheard of. No, we have no real evidence either way about MH 370 yet. The conflicting information we're getting from Malaysian authorities and well-placed leaks is confusing enough, the last thing our intelligent discussion needs is confident assertions of fact without evidence.

If not smoke, why not carbon monoxide? It's colorless, odorless, and creeps up on you and disorients you before killing you. Maybe there's a fire, a small one, in an area of the plane like the avionics bay that doesn't get a lot of O2. Isn't carbon monoxide produced by incomplete combustion? The pilots get an electrical fire alarm and start pulling breakers, unaware that they are in the first stages of CO poisoning. Maybe they succeed at extinguishing the fire and then change course to try to find a runway to set down on, but they're too far gone to pull it off, and the plane full of dead people crashes into the Indian Ocean hours later.

But really, at this point, I think my money is on terrorist attack gone wrong. But I think almost everything, from fire to theft to pilot suicide is still on the table. And I have no money.

As others have suggested, major airports should have 24hr access to a search team that includes fast fighter jets with powerful radar that can be scrambled as soon as contact with any major flight has been lost for a significant amount of time and can co-ordinate with military ground radar.

Smoke inhalation

Which is why they are trained -- repeatedly -- to put on the masks the moment they sense smoke. These masks go on incredibly quickly. Indeed, for most airlines, one pilot is required to be wearing the mask if they are alone in the cockpit above FL250 or regardless if they're above FL410.

There are checklists for in cabin fire. Here's one for a BAe 146 (scroll to figure 3.) Items in CAPS are referring to controls with that label or a setting on a control.
1) Oxygen Masks: Crew don, EMERGENCY (set oxygen switch to EMERGENCY)
2) Smoke Goggles: Crew don
3) Crew Communications: Establish (make sure you can hear each other)

4) ATC Transponder: A7700 (International code for emergency)
5) Air Traffic Control: Inform
6) PANEL FLOOD LIGHTS: Select STORM (Brighten panel in case of smoke)
7) Flight Deck Emergency Lights: ON (More light on the FD.)
8) GALLEY SWITCH: SHED (if fitted) (I'm assuming this means "cut power.")
9) FASTEN BELTS: ON
10) CABIN EMERGENCY LIGHTS: ON
11) NO SMOKING: ON
12) Flight Deck Door: Closed

Note:
1) Land at nearest suitable airfield
2) If source of fire can be identified, continue with appropriate procedure below
So. Mask On, Goggles On, Check your other pilot, Transponder to 7700, call ATC, then, if you know what the source of the fire is, ONE of you goes and deals with it. The pilot flying flies the plane, period. Note the order. Mask/Goggles. Transponder to Emergency. Call ATC. Configure a/c for the emergency, then and only then does one of you go deal with it.

ANYBODY following the checklists calls ATC. There are zero cases where you cut the power to the transponder and the radios first unless you have completely and utterly ignored the checklists about fire. That's not impossible, but it is incredibly improbable because of the repeated training they get on just this item. The fastest way to lose the plane is for the pilots to lose oxygen, so if there's any hint that oxygen is at risk, masks go on.

Fire is not a credible answer here. Fire in no way fits the facts. This is why the pilots who fly these planes are saying that the plane was flown the way it was, and it was not downed by a cabin fire. If these pilots were dealing with a fire, the first sign would have been the 7700 squawk, and the second would have been a mayday or pan pan call to ATC.

They did not squawk 7700. They did not contact ATC. They either completely and utterly disregarded the checklists, or they had no fire.

This plane was either deliberately flown somewhere by the pilots, or it was hijacked. There are no other explanations on the table that fit the facts and involve entities that actually exist. If we waive that last requirement, alien abduction and assumption into heaven also match the facts as we know them.

For this to be a fire, it needed to burn far longer than we've seen, and the flight crew needed to completely ignore their training. I can see a small chance one of those happening, but both? No. Occam says this was not a fire.

There are testimonies that I am more likely to believe, like that Vietnamese ATC "frantically" tried to establish contact on 121.5 for example.

Yes, that's step #2 if you should have contact with a flight and they're not responding on frequency. Step #1 is to go to their last assigned frequency and see if they forgot to switch. 121.5MHz is the international aircraft emergency frequency, everybody on the ground monitors it, and most airliners will monitor it if they don't need the 2nd/3rd radio for something. Usually, though, the 3rd radio is the ACARS datalink.

It's called the VHF guard frequency. If you're intercepted by military aircraft, you get on 121.5, because that's where they'll be calling you. The military version is the UHF guard frequency, 243.0MHz.

Honestly, I agree with your analysis, there was likely not a fire. But one of the common features of major disasters is a bunch of things going wrong, none of which should have. That's why disasters aren't that common--there are usually redundancies and it's not likely everything fails at once.

Here, you have evidence that things did go spectacularly wrong, which is evidence that multiple unlikely things did happen in close proximity to each other. So yeah, it's unlikely that you had a fire & and poorly reacting crew at just the moment when the plane was between ATC regions...but something unlikely happened. My non-existent money is also on crew action, but the knots seem too complex for Occam to cut them at this time.

posted by readery at 11:58 AM on March 19, 2014


/This plane was either deliberately flown somewhere by the pilots, or it was hijacked. There are no other explanations on the table that fit the facts and involve entities that actually exist.

It's hard to believe that the various governments involved can't identify potential hijackers from the passenger list after 10 days. So the odds are it was a pilot? For some reason I found the media rush to blame the pilots very distasteful, I think a lot of people did.

Having said that I do believe they'll find the wreckage off Australia so maybe we'll know.

Here's what I don't understand about the black box, cockpit recorder, and related telemetry:

Why are they not broadcasting data in regular bursts? I understand the engines send telemetry data back to Rolls-Royce, but why for example is the cockpit recorder not just permanently broadcasting? Don't we know by now that keeping data all in one place is a recipe for lost data?

FFFM: This was discussed some time ago - continuous broadcasts would be expensive and resource-consuming, since you'll have hundreds of planes broadcasting immense amounts of data all the time. The tech isn't quite there yet.

I understand the engines send telemetry data back to Rolls-Royce, but why for example is the cockpit recorder not just permanently broadcasting?

There are a *lot* of planes in the air. Build a network to handle running telemetry for every flight in the world is not a trivial thing.

Most spaceflight uses realtime telemetry. But there's exactly one ISS. There were four shuttles. There are something on the order of 5000 737s flying, and most of them are flying every day. US regulations require them to store 88 different parameters, most store far more, taking them several times a second, but sometimes faster if there's enough change.

It's a lot of data to stream. It's a hard problem for one aircraft. It's hard squared for one airline, and it's hard to the fourth power for all airlines.

Right. We can put broadband internet with near continuous coverage on a lot of aircraft, but it's expensive. It's probably possible to continuously monitor lots and lots of aircraft, but it just hasn't been worth spending so much money to do it. Black boxes, transponders and CVRs have done the job well enough.

I wish people would do us the courtesy of reading the discussion before posting. We've been talking about the feasibility of satellite uplinked data for over a week now. The 2011 article In tech's golden age, why can't black boxes do more? does a great job explaining the limitations. It's not so much a technical problem but more of a cost problem; airlines don't want to pay for the equipment. It's not an accident that it's an engine monitoring system that happened to have a satellite uplink. In that case, the engine manufacturers have a business case to pay for that uplink.

No type of uplink would help against a pilot who's deliberately sabotaging systems. Unless the uplink itself were tamper-proof, which then raises other risks. Aviation is predicated on the belief you trust the guy in the cockpit.

Indeed. See also Air Canada 797 where 23 people burned to death in 1983 because airlines had been putting off paying to install smoke detectors and emergency cabin lighting. End of the day, air carriers and plane manufacturers are going to resist demands to install equipment that costs them money, at least until they are either required to by regulation or it becomes cheaper than losing lawsuits.

I like the idea of GPS position uplink, and like I said the very day the plane disappeared I think it should be required equipment. But it's not clear a GPS position uplink would significantly enhance safety. Also worth noting; airplanes already require equipment broadcasting their GPS position to satellites in case of an accident; the ELT. Unfortunately the ELT apparently didn't go off in MH 370. It didn't work in AF 447 either. A continuous uplink would be better, but it's not a panacea.

Hell, this is even a place where the engine manufacturers could step in. The engines already send a small amount of telemetry data, how hard would it be to step that up to (say) every half hour (or more frequently) with GPS data? It's really not a lot of data to be sending, less than the average SMS AFAIK.
posted by feckless fecal fear mongering at 1:55 PM on March 19, 2014


We've been over this. The risk of fire from malfunctioning equipment that cannot be turned off is very much non-negligible, and that is a huge barrier to certifying any such hardware. The only benefit would be faster SAR in a deliberate sabotage case, not a safer aircraft.

The same data stream (ACARS) that transmits engine data already does transmit position information (in various cases). That's how AF447 was located. But it was disabled during this flight by somebody in the cockpit.

Seriously, there are reasons behind all of this, many of them already discussed in this thread.

The only actual argument is cost, and I DGAF about that; airline manufacturers, as pointed out above, will resist anything if they think it'll cost more, and the only way to force them to do so is to make it legally or financially impossible not to.

I think it's an open question whether there is sufficient free bandwidth on the relevant satellites to justify the overhead of 20,000 odd flights simultaneously phoning home. You can't just send these messages over some nebulous network: in order to satisfy the purpose of being a globally reliable location transponder, it requires a correspondingly reliable network. I think Iridium's constellation provides the most coverage, but I know even it has dead areas.

Stick 'em with the SAR bill and boy howdy will you see changes.

Let's run the numbers. (I think I got these all right but I'd welcome any corrections to my math)



According to table 1, there were 9,989.9 thousand flights in 2011 and 9,821.0 thousand in 2012. Let's call it an even 10 million for conversation's sake.

Since we want these location results to always be available, we're presumably not going to depend on radar or other radio based methods. Instead we'll use a satellite like SPOT.

Handily, SPOT offers asset tracking, which for $99.99 a year will transmit coordinates every "every 5, 10, 30 or 60 [minutes]." That's cheaper than the messenger plan which offers SMS and other features for $149.99 a year. If you'll forgive my rounding again, that's $1,000,000,000 per year. Kind of steep, but a fantastic price IMO. If we're broadcasting every 5 minutes during the average of 8 hours and 28 minutes per day a year that Air New Zealand's fleet flies, we're looking at 102 transmissions a day, or 37,084 per year. Per plane.

Probably not the type of usage SPOT intended so I think they'd be more inclined to charge more instead of handing out a bulk discount, but hey, a price lists's a price list. 26¢ per ping sounds pretty competitive to me.

In the other corner, we have the MH370 SAR clocking in at an unprecedented Rs 800 crore. (Crore is a South Asian unit of numbering equal to ten million)

At today's exchange rates, Rs 8,000,000,000 is $131,232,000 USD.


Looks like we're going to need almost 10 more huge SAR operations to pay for our GPS system.

All aspects of aviation involve cost considerations, because air travel is a price sensitive market. You could sink the same money into many other things to achieve measurable improvements in risk or safety, beginning with better pilot training.

You can't just pass costs off on third parties like manufactures. You will end up paying for it as a traveler or taxpayer somehow.

feckless fecal fear mongering: "A self-contained GPS unit is proof against fire."

Even accepting the premise that self containment is proof against fire or at least a fire that endagers the airframe, complete self containment is going to be a difficult task. You need to bring power to the device which I guess could use inductive coupling to a battery so that the device could operate even if the feed is turned off. You need to provide a self contained transmitter and antenna powerful enough to hit either a land based monitoring station or a satellite from the middle of the Pacific or over the North Pole. And you have to certify the package (and power connections) for every airframe you want to install it on. Even a simple thing like the cockpit vestible screen linked earlier costs tens of thousands of dollars. And then as noted above you need to pay for monitoring of the signal. And you need to pay for testing and maintenance of the transponder. And the cost of fuel to fly these devices.

Resulting in a system that is already essentially provided by existing systems with the net result being maybe a few flights a century don't disappear into the ether.

There must be dozens of other things we could do with that kind of expenditure to make flying safer or less horrific.

From yesterday's New Straits Times,
According to a commercial airline Boeing 777 pilot who requested anonymity...

It is MAS procedure to switch ACARS ...off...but this is only for flights to China as the service provider for MAS does not cover China. Some if not all pilots switch them all off for a while and then later switch SATCOMM back on to force the system into SATCOMM mode.”
That the NST is saying this is news. The quoted pilot has no explanation for the transponder being turned off.

Watching travellingwithcats' link to yesterday's press conference, it appears they are backing away from the zig zag waypoints:
Q: Can you confirm that after the turnback radar data shows that the plane passed through at least two waypoints before it headed out into the Bay of Bengal?

A (Azharuddin): I think that was something that we were (?) going to investigate. I think we have passed through that stage now. What we're going to do now is find the aircraft. Let us investigate on that.

Q: Do you have a picture(?) that shows it passing through?

A: I think that is something the investigation is doing. What we're going to concentrate now is on finding the aircraft. That's why we have the northern and southern corridor.

A (Hishammuddin): The reason why we are looking for the aircraft is that we hope that by locating the aircraft we are able to find the black box. And if we do find the black box then your question will be categorically answered.
I'm so confused.

According to this summary of the Iridium constellation, it can accommodate 172,000 users presumably of the now-obsolete phone service which IIRC delivered 28kbps. Nowadays they offer packet comms similar to SMS with a module capable of both up and downlink requiring 5VDC at 500 mA and a simple omnidirectional antenna. Make: magazine ran a squib on them last quarter; they are actually accessible to hobbyists. It should be possible to make such an avionic module small, durable, and with considerable built-in battery life after mains failure. I think the main problem on an airplane would be getting the antenna outside of the aluminum fuselage.

Assuming 172,000 voice users x 28.8 kbps = total network bandwidth of around close enough to 5 gigabits/sec to consider the difference a rounding error.

Several sources seem to show around 5,000 flights in the air with ADS-B enabled, meaning they're large commercial either in, to, or from the US, or enabled for such flights. Let's say there are 20,000 planes that should be tracked globally. If we were to devote Iridium entirely to them, that would give us a channel of 250 bits/sec to every airplane flying. In practice that's truly excessive. A packet containing full plane ID and GPS position and velocity is well under 1 kilobit. This means the Iridium constellation could carry such a message from every large plane flying in the world about every 4 seconds.

That in turn is also excessive; should such a system make such a ping every 5 minutes, or even every 10, it would hugely narrow these searches when the worst happens. At every 5 minutes -- a frequency which would give you a 50 mile fix on the fastest commercial jets -- the global system would consume about 1.5% of the Iridium system's existing global bandwidth.

Contrary to something stated previously there are no holes in Iridium coverage. It was designed to be globally continuous and despite the loss of a couple of birds (one due to a space collision) it still is.

So while there is the issue of the vastly inflated cost of engineering it for aircraft and deploying, the satellite infrastructure to collect the data does exist and such pingers could be battery powered for some time just like the black boxes. A next generation Iridium constellation is also in the works, which is intended to be compatible with the existing system but would vastly expand the global bandwidth and make the whole thing even easier.

Hm, that is an interesting tidbit. This was a flight to China but even if it was recommended MAS procedure to switch ACARS off, they were about to enter Vietnamese airspace so it would have been premature to do so at that point. And like with all the anonymous sources, it's hard to verify their motivation and the info itself.

Re: waypoints. I found it odd that they were unwilling to give a straight answer to that question and instead talked for almost 90 sec IIRC about that it was not relevant anymore. I guess the data they have leaves a lot of room for interpretation. As they get new data, they might have to adjust their assumptions.
Besides, as I mentioned upthread, there might be other reasons that prompted them to label it "deliberate action" (hitting waypoints was part of that justification). Now that it is a matter of terrorism (as per sec. 130 of their penal code) they likely have other means and measures available vs. before.

Putrajaya knows where MH370 is but is not telling to protect its interests, says aviation expert:

"We’re dealing with military organisations, and they don’t want to tell you, and especially they don’t want to tell you if it looks like they really screwed up," Hans Weber, a San Diego-based aviation consultant, was quoted as saying in the article.

"The military doesn’t want to look bad in its own country. I think there is a lot of incentive for the militaries there to not come clean.

However, the article said there is no evidence that anyone knows where the plane is, while pressure is building up from grieving families of the passengers and crew on board for an answer.

They diverted a merchant ship to the area. There is a warship capable of recovering anything that is found to be from the flight, but it won't be there for a day, I think. They also mentioned US Navy involvement, I believe.

I really hope this new development actually pans out. Definitely keeping my fingers crossed. (I thought ELTs on aircraft were either at 121.5MHz or 406MHz, though, so my confidence in the reporting being done is somewhat low at the moment..Also, I could do without WSJ's continuous bullshit machine, but we all know how likely that is to be turned off even for a little while.)

Also, regarding Iridium, localroger's calculation is all well and good, but is a measurement of the total system capacity, not the capacity of any individual Iridium satellite. Since the vast majority of flights take place in one of about three or four relatively small areas, the actual bandwidth available would be much less.

Mode S* (on which ADS-B is based) is cool, but the primary reason it exists is not for improved accuracy and lower cost to ATC than operating standard radar in sparsely populated airspace, but because there were so many planes flying around in European airspace that the Mode A/C transponders were saturating the available spectrum and talking all over each other.

*S stands for "select," as in selective interrogation.

All aircraft flying in European airspace above a certain size are required to have a Mode S transponder at this point. The FAA will be requiring ADS-B come 2016. Why do I mention this? Because aircraft so equipped "squit" their position unsolicited once every few seconds. Some equipment also includes information like a "cleared to" altitude from the FD, among other things.

And, alas, there's a lot of crap in the oceans.

24m is 78 feet, if that's debris from the plane, it's a fuselage piece, a wing piece, or one of the stabilizers, which are 21.5m/70' long. The fuselage on a 772 is 63m/209' long and 6.1m/20' in diameter. The wings are about 53x10m (180x30'), the horizontal stabs are 21x5m (68x16'), and the tail fin is 18x4m (59x13').

The first object has a hint of a curve to it, which implies fuselage. This may well be me reading something into it, but I suspect that's one of the big factor to send the planes out.

The second object is a blur, indeed, in panchromatic, it's really not classifiable as an object, but the multispectral imager is much clearer about something being there.

WARNING: This may be a false alarm. This debris may not be related to the flight.

I thought ELTs on aircraft were either at 121.5MHz or 406MHz, though, so my confidence in the reporting being done is somewhat low at the moment.

They are, but the 121.5Mhz ones have been deprecated for years. The newer (and by newer, I mean the last 20 years) ones run on 406MHz. They're both more accurate in position and have a serial number, so if you've registered it, it says very clearly that *you* are in trouble, not that somebody is in trouble. There were also ones on 243MHz, they've also been sunsetted.

While I can see someone in a small craft cheaping out with an old 121.5MHz unit, I don't see a flagship carrier like Malaysia Airlines not having a 406MHz ELT.

I have no idea what they'd be hearing on 347Mhz.

On Iridium: The design spec for the Iridium constellation is that there should always be at least one bird 20 degrees above the horizon at all times. Right now this tool says I have two.

Of course, as with GPS, if that bird is behind a bunch of trees, a canyon wall, a metal building, or a lot of dense nasty clouds and rain, you may not get a connection. None of these are factors for a plane in flight though. Also, because the service is duplex, the pinger knows whether it connected, and can retry the ping if it fails.

Of course nobody designs a real system based on using its maximum bandwidth but that's always a starting point. Actually, the 5 gigabit/sec bandwidth figure is Iridium's claim for maximum voice users; that may already be downgraded from the real theoretical bandwidth to something they consider realistic throughput. Even if it isn't, it's hard to imagine a situation where a system would be flooded by continuous use of 2% of its theoretical maximum bandwidth. Even if you happen to have a lot of planes in a place served by only one bird at the moment, as noted above it's duplex so any pings that fail due to message collisions can be retried. The voice service would pretty much have to be engineered that way to work at all.

This is all not to say that such a system should be built, only that the math says it is actually possible and that the space infrastructure does already exist to support it. The cost vs. benefit numbers are very hard to run because yeah it's very expensive, but the SAR and recovery are also very expensive when a plane goes down, most especially when it goes down in a remote location which is exactly what the system would be for.

There is something of an emotional component to the money we throw at aircraft recovery, because even though cars kill far more people than airplanes there is a much greater sense of helplessness in the grip of mighty forces when you are killed by the airplane. You personally have a lot more control over whether you're killed by a car, so people aren't as invested in calling out the satellites and nuclear subs to figure out what happened when someone drives off a cliff.

24m sounds awfully big for a floating piece of aircraft debris. My suspicion is that big chunks of fuselage will all sink, and the floating debris one expects would be smaller bits and pieces that have a bit of buoyancy to them. Parts of the wing might be the best bet. If I had time I might check what bits of AF 447 were first to be recovered and which had to be located on the sea floor.

24m sounds awfully big ...
Picture showing AF crash debris ... ~10-12m, floats and holds several people standing on it.

So some questions:
1) What does the image timestamp refer to? When the satelite took the photo, when it was downloaded to a terrestrial server?
1a) Is there any post-processing required of the image and how long does that take?
2) Should any protocol be followed before releasing images to the public. For example, perhaps consulting one or more crash debris experts, notifying the various national and international government agencies of the finding, etc, and how long does that take?
3) When were the SAR assets notified to investigate further, could that have happened prior to the release to the public?

I enjoy the counter-claims and alternate theories, but if you can't provide anything to back up a counter-assertion, then why bring it up at all? It just adds noise.

I was curious about the report of 347 MHz, but the tweet by @radioditch that was the source was deleted and I can't find any other reporting about that frequency. Probably just a mistake. Emergency Locator Transmitters broadcast on 121.5 MHz and 406 MHz and are designed to be picked up from satellites; the lack of an ELT signal with MH 370 is part of the problem. (AF 447 also had no ELT signal; I've yet to find the analysis on why it failed.)

The Flight Data Recorder ("black box") also has a beacon signal to aid recovery; according to this source it "radiates a pulsed acoustic signal into the surrounding water upon activation of its water-sensitive switch, and will activate automatically on submersion in salt or fresh water with an operating life expectancy of 30 days to a depth of 20,000 feet." So audio, not radio, presumably so it works well underwater. I imagine that's part of why sub-hunting equipment is used to look for underwater airplane wrecks.

New position reports for the plane were posted in this thread. Thanks!

Westringia posted this WashPo article which shows arcs for 5:11, 6:11, 7:11, and 8:11 leading to the search area. That article still has no information about the plane between 2:15 and 5:11. I'm not certain from the article's text, but I think those arcs are backtracked from the search team's hypothesized plane track rather than directly from Inmarsat data.

bobloblaw posted a diagram which seems to be sourced from this tweet by Scott Henderson @_AntiAlias_. It's appealing in that is has arcs for 01:11, 02:11, and 04:11. But it's entirely his amateur reconstruction based on the NTSB probable tracks, he says "arcs are symbolic of where the arcs could be to give NTSB track.". I don't consider this reliable.

Reading between the lines, I think no one has released the source data for the Inmarsat location fixes; everyone's working backwards from the search team's track hypothesis (which is presumably based on the Inmarsat data). Is there a better version of the official track hypothesis than these yellow lines? From an official source I mean, not the various fan fiction maps floating around.

Thanks, de, that's great. If I may summarize, it's AMSA saying they used the Inmarsat data along with assumptions about the aircraft speed to come up with the two tracks. I just keep hoping to see the source data for myself, I find the technology fascinating.

Thank you for the link de. I am a bit confused by the explanation given. Young says:

"AMSA has defined a possible search area with information available to us from a range of sources, both international and national."

"What we have done, is to work with the US NTSB, which has [...] already done some work on transmissions that were made from the aircraft at approx. hourly intervals during its flight. And both transmissions were detected by a communications satellite over the Indian Ocean. And with the time of those communications and the distance they can't plot an exact position for each one, but sequentially they can be build up into a possible path that the aircraft took. The search area you see here is based on the last one of those reports, what would likely happen to the aircraft after that and it has then been moved to account for water movement and weather since the 8th of March."

Yeah those maps on airliners.net from socialgeo are what I dismissively called "Fan fiction". Some random guy is speculating on what could have happened.

Maps can be particularly infectious misinformation because they look so certain. I think it's irresponsible to share speculative maps without some strong disclaimers or indications of uncertainty on the map itself. That WNYC map of 634 runways also felt irresponsible to me since it brought so much focus to "where did the mystery plane land?" when there was no evidence it landed at a runway at all.

I really, really hope they find the cockpit recorder.

I thought the voice recorder records in a loop. I forget how long the loop is, but no more than two hours — it used to be only 30 minutes. So if the last several hours were straight flight and the pilots were incapacitated, then it's likely to be just silence. The data recorder has a much longer cycle so it should have data from the full flight.

The WashPo article talks about what we expect to find on the black box. 25 hours of flight data, 2 hours of cockpit audio, 2 hours of "digital messages". I don't know if that's 2 hours of time including silence or 2 hours of actual sound. It's tempting to speculate on how useful this data will be if it's recovered, but it's kind of pointless to.

For timing reasons, basically. And because an aircraft cockpit isn't very silent, and you want to be able to pick up very quiet sounds. It's amazing how many accident reports have used the particular sounds that different types of switches in the cockpit make as evidence.

P-3s are extremely fuel efficient, they can fly for an entire day with no need to refuel. But it does take them 4 hours each way to/from land. My guess is searching during nighttime is too complicated/expensive for a non-emergency situation but I'm not sure about that. In addition to radar they can detect submarines with a magnetic anomaly detector but I don't know if that works on airplanes (aluminum is much less magnetic).

From ABC News [US]:
Inmarsat, the maker of satellites, told ABC News that they had an "initial idea" on March 9 and by March 10 were "fairly certain" that the search parties should look in the south Indian Ocean for the vanished plane.

Inmarsat shared their data with a partner company the following day, on March 11, and with Malaysian investigators on March 12.

It was not until three days later, on March 15, that Malaysian authorities acknowledged that satellite data suggested the plane was not in the Strait of Malacca or the South China Sea and began redirecting search efforts to the Indian Ocean.
It was on March 11 that the Director of the CIA said terrorism could not be ruled out and everyone fell down the rabbit hole of Kazakhstan.

[on preview]
re the NYT infographic linked by Nelson: I always thought the wonky altitude (up to 45000 ft, down to 23000 ft) happened when the plane turned back over the Gulf of Thailand. It happened after it crossed over the peninsula, in the Straits of Malacca at 2:15AM.

Re Lithium batteries:
"These are not regarded as dangerous goods... and were packed as recommended by the International Civil Aviation Organisation," said Malaysia Airlines CEO Ahmad Jauhari Yahya.

I believe these are the IATA regulations that they are referring to. Quite newly introduced after the 2010 UBS cargo plane accident I linked to above. The regulations clearly classify lithium batteries as dangerous goods and adds on page 11: "Primary (non rechargeable) lithium metal batteries and cells, (UN 3090), are forbidden for transportation aboard passenger carrying aircraft." Only if the cells are contained within devices may they be carried - and the total number of cells is small in terms of number and weight - may they be carried at all.
posted by rongorongo at 8:34 AM on March 21, 2014


A (significant) lithium battery fire would have almost certainly caused a crash long before fuel exhaustion. The Halon fire extinguishers they use in the cargo compartment cannot stop lithium fires. They do prevent open flame, but not the shit-ton of heat, and as soon as it dissipates, blammo, huge fire again. This is because heat causes the lithium compounds in the batteries to decompose, releasing oxygen inside the battery itself, where the Halon cannot reach.

They did some related testing after the UPS crash in Dubai if anyone is interested in knowing more. It's in the report, whose link I don't have handy, but is probably somewhere upthread.

Yeah the Telegraph liveblog is a big zero, as is all the news today. But they were promoting a link to a good article: How MH370 vanished - and how it could have been avoided which describes in details all the communications from the missing plane.

This article is the first place I've seen it reported that it's impossible to turn off the thing that was pinging Inmarsat satellites. That's interesting and, honestly, surprising to me. I've been careful to say all along it's not impossible or even a bad idea to have some sort of GPS pinger the pilot can't disable. But it would be unprecedented. Well, here's a precedent. (A second one; as pointed out above the black box recorder is also impossible to disable. In that case, specifically because the pilot is not trusted.)
posted by Nelson at 10:40 AM on March 21, 2014


Neither the black box nor the Inmarsat equipment is impossible (or difficult) to disable. They both have circuit breakers, like every other piece of electronics. Pulling the circuit breakers on the FDR/CVR is sometimes done intentionally after an incident (when back on the ground) so that they don't continue to record and overwrite potentially relevant information.

Maybe there's no "off" switch on the hardware itself, but a circuit breaker will certainly do the same job.
posted by kiltedtaco at 10:50 AM on March 21, 2014


Yeah, the argument I've seen in some places that the pilot needs to be able to remove power from any electronics device on the plane including the black box in case of electrical fire or whatever seems specious to me. Can they remove power from all of our laptops?
posted by Golden Eternity at 10:53 AM on March 21, 2014


Yeah, by switching off the seat power. The plane generates electricity with enough current to continue to feed a fire. Your laptop is not connected to the aircraft's electrical system unless you have it plugged in, so is not a danger in the same sense that a built in electrical device without a circuit breaker would be.

posted by fshgrl at 11:34 AM on March 21, 2014


Removing power from a laptop will not turn it off because laptops have batteries. The FDR and CVR also have batteries for the underwater locator beacons. Supplying relatively fire-safe battery power to a device like a GPS pinger for a period of a few hours would not be a difficult technical challenge.

At least in the world of high-drain batteries (e-cig mechanical mods, flashlights, RC vehicles, that stuff) there are a number of safer chemistries like the AW IMR batteries that basically vent out before thermal runaway gets to the point of starting a fire, but I don't know if that chemistry exists for the kind of batteries you need for long life/low-drain applications like transmitters. I suppose you could design a failsafe that automatically ejects the battery out of the plane if it reaches a certain temperature, or put the whole thing in a fireproof box with external ventilation that kicks on when it reaches a certain temp, but now you've got systems on top of systems and more points of failure. Maybe a completely external box that's sealed from the elements but has weak spots intended to blow if the battery vents or combusts. It isn't by any means impossible, but it isn't trivial either. Battery failure of consumer devices on the plane would be an even trickier problem to solve.

Are you certain of that? Do you have a reference? The Telegraph reports "there is no way that it can be switched off unless the plane itself loses power, according to Inmarsat." If there were a circuit breaker, I'd expect it to be mentioned there, but maybe it's just sloppy reporting. I understand that aircraft electrical systems traditionally have circuit breakers and I'm wondering if this equipment is different.

(I'm also curious about black box power; surely it's designed to continue recording what it can even if the entire electrical bus fails?)

The Sydney Morning Herald suggests pilots polled on the probable cause (assuming the area being searched for debris is where MH370 ended up) - favour an event which rendered crew unconscious, followed by a ghost flight until fuel exhaustion. This article looks at what happens when a plan runs out of fuel. And this one suggests a couple of potential causes including a broken off satellite antenna and an explosion in the crew's emergency oxygen supply.

I think a ghost flight is a good theory for what happened in the end and why the plane seemingly flew until both engines flamed out, but a fire can't be the cause of this due to the length of flight. That leaves us with some kind of decompression issue, which could have been caused by an accident or something more sinister. If it was an accident why did the plane climb to 45,000 ft, way above its threshold?

CVRs were recently (2008) required to add a 10-minute battery (technically a RIPS - recorder independent power supply - so as to not require a specific energy storage technology) to address bus failures. It affects new aircraft built after April 2010 only. There is no FDR battery requirement because it relies on outputs from all the systems on the plane.

As far as breakers for the SATCOM, looking through one particular 777 AMM I see many breakers controlling several different components of the system, but I admit that the incident aircraft could have a different type of SATCOM hardware that does something entirely different (but I think that's less likely than a miscommunication by the newspaper). I can't say for sure without having that specific aircraft's manual.

I'm reasonably convinced that the last six or so hours of the flight were a ghost flight. Whatever the cause of the initial issue was, accident, suicide attempt, hijacker, I don't think anyone was alive in the cockpit by the time it was flying south towards Antarctica. The question is, when did it start? Given it appears to have been following flight points, it's possible that it could have started much earlier. If they were essentially random, it would explain quite a bit. I know people have been linking to those maps from airliners.net and saying they were avoiding radar, but when you actually look at the radar and not giant crayoned marks on them, the plane would have avoided more radar by flying on at the first turn heading. The Gival to Vampi zigzag in fact keeps it in the densest area of radar coverage by *three countries*. It makes no sense for reasons malicious, but it would also be a rather inefficient way to alert for a hijacking. Yet if it was random, how the hell did those particular waypoints get in?

At the moment, I have severe doubts that anyone in the plane was alive after the altitude changes.

Supposing it were a ghost flight and there was no mechanical change in the cockpit (ie nothing leaning against the controls), how would a plane come down? Would it keep level and just gradually glide lower?

The high-speed crash from that Wikipedia link sounds like the attacker probably grabbed the controls and pointed it downward at a sharper angle while it still had full power, no? So that crash might have experienced much greater forces on impact than a hypothetical ghost-flight/fuel-exhaustion scenario?

This has been addressed:
[A]ltitude might have prevented passengers’ cellphones from connecting to base stations on the ground even if the phones were turned on during the flight or had been left on since departure. ¶ The hijacked planes on Sept. 11 were flying very low toward urban targets when passengers and flight attendants made calls from those aircraft. . . . ¶ Base station signals spread out considerably over distance. So cellphones in a plane a few miles up, like Flight 370, would receive little if any signal . . . .

The craziest thing about that story is not the speed on impact, but how he manages to deliver hollywoodesque one liners in the midst of a mass murder-suicide.

5k g's That's crazy! I don't buy it.

The plane was travelling at 1,240 km/h. That's 1,240,000m/h, or 344ms-1.
If it decelerated from 344ms-1 to 0ms-1 in, say, 5m (randomly guessing at a 5m deep impact crater), then the deceleration took roughly:
5/344 = 0.01453s
Which makes the deceleration:
344/0.01453 = 23,675ms-2
1g is 9.81ms-2
So the plane experienced:
23,675/9.81 = 2,413g
That's the average g sustained during the crash, but it wasn't a constant force, it would have maxed at double that at the start and reduced to 1g at the end, so
2,413g x 2 = 4,826g
So yeah 5k g seems about right, and like cortex said, it's just that amount at the instant of impact and it reduces after that point.

Passenger jets are designed forty ways from Sunday for stability, so even without power it would be very unlikely to auger in. That's a very rare crash mode because it almost has to be commanded, but you saw it with United 93, for obvious reasons, and also with ValuJet 592 which sustained very heavy fire damage to its controls. Both planes more or less disintegrated on impact.

I had a crazy thought this morning, lying in bed a 6:30 am. Do you think it would have been possible for an array of hydrophones to triangulate the position of a plane crashing into the ocean? I've realized now that the array I've linked isn't anywhere near the Indian ocean, and so is probably irrelevant, but does anyone know if such an array operates in the area? I guess if I did, the experts would be onto it.

Jimbob, the whole problem with the southern Indian Ocean is that it's not only one of the remotest places on Earth -- worse even than Antarctica, which is dotted with research stations -- it's not on the way from anywhere to anywhere else, either, so there's no particular reason for anything to be there. Although it's fortunately found other purposes the main justification for the hydrophone system is to track nuclear submarines, whose purpose in the whole nuclear war game is to hide. Inasmuch as the southern Indian Ocean is about as far from the United States as you can get without leaving the planet, it's a pretty bad place to hide your nuclear assets if you're planning a strike on the US, so there's not much reason for the US to target the area for sub detection.

So now Malaysia is requesting US "underwater" assets. I knew those 688's would come in handy. If anything can find those pinging boxes, it's a US fast attack boat.

They've probably been prowling the area for days now, so I don't expect it will take them long to find the boxes. Then again, they'll not want to tip their hand regarding their capabilities, so they'll probably delay any "news" for a bit.

If some object had shattered the cockpit windshield (from either inside or outside), what would the effect have been?

The cockpit windows are layered and tested against such threats - in particular bird strikes. If the object hit from the outside with such force that it managed to penetrate the window, it could injure the crew member immediately behind, but I couldn't find examples of any such occurences in airliners. The GA aircraft are much more vulnerable.

Otherwise, window panes crack for a variety of reasons, this is a potentially serious but usually contained failure.

As to the effects of decompression, there was an accident where a whole window frame separated at altitude: BA Flight 5390. They managed to land safely.

Most people I speak to here acknowledge that an incident like the disappearance of Flight 370 is unprecedented and say they appreciate the monumental task facing the government.

For many, however, the authorities’ ponderous response and mishandling of information mirror the way Malaysia is run.

The offhand, sometimes defensive nature of the early press conferences, coupled with occasional attacks on the foreign media, are widely perceived as the arrogance of a government unaccustomed to global attention and accountability.

Phone records of Captain Zaharie Ahmad Shah have reportedly revealed he took a two-minute phone call from a mystery woman using a mobile phone number obtained under a false identity, The Mail Online reports.
Investigators are understood to be treating it seriously because anyone buying a pay-as-you-go SIM card in Malaysia has to fill out a form giving their identity card or passport number.
This ensures that every number is registered to a traceable person.
In investigations into the Captain’s life, police are believed to have traced the number to a shop selling SIM cards in Kuala Lumpur.
It was bought “very recently” by someone who gave a woman’s name – but was using a false identity.

(Upon reading the article more thoroughly - the debris seems not even that strongly suggestive of wreckage from MH370. One of the items was a wooden pallet, the other items were not identified in the article, and they were found in the search area "within a 5km radius". Another plane was not able to find the debris. A marker buoy was dropped and a merchant ship has been asked to find and identify it. Based on the headline I thought this was going to be a breakthrough. Ho hum!)

Note: The actual airliner pallets (LD7, LD8 and LD11) are made of aluminum, and are designed to be mechanically handled. However, it's not uncommon for the shipper to put a wooden pallet onto the airline pallet to speed transport once the load is off the airplane, see this image for an example. So, it's not impossible for that pallet to have come from MH370.

You can also see the clever machine that loads them -- the rollers on the deck of both the base level (for getting pallets on to it) and the lifter are driven. The operator can rotate them, if needed, pull them onto the lift deck, lift them, then slide them into the aircraft. The aircraft also has systems to move the pallets into place and lock them down. On a passenger flight like this, the last container in will be passenger luggage.
posted by eriko at 6:46 AM on March 23, 2014


Yes, if the shipper plans to transfer the entire pallet load to ground transportation they will need another pallet because the aluminum airline pallet is both specialized for air transport and property of the airline.

The Malaysian Ministry of Transport made an important correction/clarification in their latest press release:

3. Update on ACARS transmission
a. The last ACARS transmission, sent at 1.07am, showed nothing unusual. The 1.07am transmission showed a normal routing all the way to Beijing.


This seems to invalidate the fact reported on March 17th by NYTimes and NBC that "the reprogramming [of the Flight Management System to include a U-turn] happened before the Acars stopped working".

But, if that was the last ACARS transmission how do they know that the Flight Management System was reprogrammed at all? The NBC article does mention that the re-program might have been an "alternate flight plan", so perhaps multiple flight plans were transmitted but the primary "activated" one was unchanged?

Today's Washington Post story cites this as the Malaysian Government's denial of "recent U.S. media reports that the flight was pre-programmed to turn around before it vanished from radar."

If this latest report is true, and the earlier reports are wrong, that's a huge deal. The reprogramming of the FMS prior to 1:07 would have really sealed the deal that it was some sort of deliberate action in the cockpit rather than a mishap, and I was giving this report a little more credence in the expectation that it might explain why the Malaysian authorities seemed to be confident that there was deliberate action involved. If it's not true, then I think weird response to a weird mishap becomes plausible again.

At this point I doubt the factual accuracy of most of what the Malaysian government has told us. The reprogramming of the FMS, the radar fixes west of the country, all of it. Far too much confusion and contradiction coming out of them. Sadly, the press leaks about Inmarsat fixes have turned out to be more accurate, apparently, at least accurate enough to convince Australia and friends to conduct a serious search operation in the middle of nowhere.

Unfortunately the Malaysian government is presumably in charge of any investigation into the pilots. Let's hope they manage that better than they did the press briefings. There were some reports of them inviting the FBI in to help, at least to look at the pilot's flight simulator. I take the lack of updates about the investigation of the crew and passengers as good news; maybe they're actually trying to get the story right before talking.

The ACARS reprogramming never made sense to me. The ACARS data they had right away, it's presumably in a standard format, if there was a reprogramming to particular flight points it would have been visible right away. Instead of having to rely on realizing fleeting radar contacts meant something, days later.

PM NAJIB RAZAK’S PRESS STATEMENT ON MH370

24 MARCH 2014, 10PM

This evening I was briefed by representatives from the UK Air Accidents Investigation Branch (AAIB). They informed me that Inmarsat, the UK company that provided the satellite data which indicated the northern and southern corridors, has been performing further calculations on the data. Using a type of analysis never before used in an investigation of this sort, they have been able to shed more light on MH370’s flight path.

Based on their new analysis, Inmarsat and the AAIB have concluded that MH370 flew along the southern corridor, and that its last position was in the middle of the Indian Ocean, west of Perth.

This is a remote location, far from any possible landing sites. It is therefore with deep sadness and regret that I must inform you that, according to this new data, flight MH370 ended in the southern Indian Ocean.

We will be holding a press conference tomorrow with further details. In the meantime, we wanted to inform you of this new development at the earliest opportunity. We share this information out of a commitment to openness and respect for the families, two principles which have guided this investigation.

Malaysia Airlines have already spoken to the families of the passengers and crew to inform them of this development. For them, the past few weeks have been heartbreaking; I know this news must be harder still. I urge the media to respect their privacy, and to allow them the space they need at this difficult time.

Where you search for the CVR/FDR and floating debris are going to be very different now. Stuff that's floating is floating in the "Roaring Forties," 40°S is infamous for the strong westerly winds and seas.

This is mainly because down there, there's no land to really stop the winds and waves. The southern parts of the Indian and Pacific, as well as the Southern Ocean, are just windy and wild. This is why sailing from England or the US west coast to India or Australia, you go around Africa, not South America.

So, the tail probably sinks quickly, taking the recorders with it. Anything still floating has drifted two weeks in a wild area of the ocean.

I'm just hoping the new work with the sat info has also helped them tighten up the potential track.

CNN has a video (autoplays) of Anderson Cooper interviewing Chris McLaughlin, Sr. VP of External Affairs at Inmarsat. Not much more technical detail but itsounds like they found some sort of pattern in transmissions from other flights and were able to correlate with the data from MH370.

In a large way, this flight has been a story about being 'off-the-grid': shut out from expected forms of communication and tracking methods and being in the dark.

I think it's fascinating that in the end, and in the middle of nowhere, Flight MH370 ultimately left a data trail to hint at its fate.

From the interview linked above: when he was asked if there's any further data Inmarsat could provide, McLaughlin (Inmarsat Sr. VP of External Affairs) replied,
Sadly, this is the limit. There's no global decision---even with the Air France flight of five years ago---no global decision to make direction and distance reporting compulsory. On ships, you have long-range identification and tracking, and they have to log in every six hours to say where they are. Well obviously on aircraft, they'd have to log in at 5-600 kts, every fifteen minutes. That could be done tomorrow, with the existing technology that we have, but the mandate isn't there globally.

From the Guardian, quoting the New York Times:
“Our measured series of signals very much mirror the predicted southern track after the last possible turn,” said Chris McLaughlin, a vice president at Inmarsat, adding that they were consistent with previous indications that the plane continued on at a more or less constant speed and direction for the last hours of the flight.

He said that Inmarsat was confident enough in the new analysis, which it reviewed with Boeing and with a number of independent aviation experts, that the company submitted its findings on Sunday to the Malaysians by way of the British safety agency, the Air Accidents Investigations Bureau.
Continuing from the NYT article inself (semi-paywalled):
“What we still can’t say is what happened at the end, when the plane ran out of fuel,” Mr. McLaughlin said. “We have no way of knowing if it dropped from the sky or glided.”

Inmarsat has provided investigators with its estimate of the plane’s coordinates when it emitted the last of the signals, at 8:11 a.m. Malaysian time on March 8. “We are very comfortable with the guidance we have been giving,” he said.
That's it for quoted bits from Inmarsat's VP, McLaughlin, in the NYT article, but it does sound like they were able to come up with a least rough coordinates for the pings. (It bugs me that the part about coordinates isn't in direct quotes. I hope it's true that they were able to do that.)

According to this slashdot comment, it looks like these systems log frequency differentials for diagnostic purposes, and by going through the logs and doing comparisons with old data or other MH jet data they were able to tease out the doppler component, which gives the relative velocity between the satellite and signal source. Since this would be different at different latitudes because of the Earth's curvature, with the Earth's surface rotational speed being different, it was then possible for them to rule out the northern route.

The aircraft had like 5 separate systems of varying levels of automation that could be used to locate it. It had an ADS-B system that broadcasts location information constantly and automatically. It had a transponder that replies to secondary radar and can be used to locate it. It had an ACARS system that also transmitted information that could be used to locate a plane. It had multiple radio systems with which you could ask the pilots where they are. And it had an Emergency Location Transmitter which should transmit information in case of an emergency. However due to the violent nature of plane crashes that doesn't always work.

I guess they could have added a sixth system. If this was pilot suicide, maybe a system that pilots cannot deactivate would have discouraged it.

Sounds like they think the passengers could have been rescued if the plane was located earlier, which is highly unlikely. But well, weeks of this would not leave most people in a terribly rational mood. For all people have been bashing Malaysia, the few days of delay in not picking up the radar track is fairly insignificant in the timeline. And hell, for the first couple of days of that -- who would even think to be looking anywhere but on the immediate track?

In fact, having just checked a timeline, the revelation of the turn and the start of searching in the Indian Sea was March 11, and it went missing March 8, so we are talking maybe 1 or 2 days at most. It's not like anyone else recognized the radar traces -- Thailand saw it, and probably Indonesia, but no one realized what it was.

No. There's been other ghost planes, and the only thing that could be done was to track their path. There's no way of controlling them externally (for very obvious reasons), and we don't have any capability to board them in midair.
posted by tavella at 12:47 PM on March 24, 2014


Very unlikely, ClaireBear. Most likely military jets would have been scrambled to make sure it wasn't being repurposed 9/11-style, and those pilots would have been able to do nothing but watch helplessly as the ghost plane ran out its fuel and hit the water.

The idea of rescuing the passengers also assumes someone was still alive on the plane after it made its last course correction and settled into the death march south.

Also, the possibility of doing a Sullenberger-style successful ditch in the Indian Ocean in the "roaring forties" is very poor. Sullenberger was able to pull it off mainly because he had a relatively smooth river to try it in. Every time it's been tried in the ocean the plane has disintegrated or cartwheeled.

Since [the doppler shift] would be different at different latitudes because of the Earth's curvature, with the Earth's surface rotational speed being different, it was then possible for them to rule out the northern route.

This doesn't quite make sense, since 1) The satellite is in geosynchronous orbit, so there is no latitude dependence and 2) North and South are symmetric in this, so there's no way to differentiate based on doppler shift alone. There must be some additional information involved, but I can't figure out what it is.
posted by kiltedtaco at 12:48 PM on March 24, 2014


Rotation of the earth. The closer you are to the equator, the faster the rotational speed. This is why space launch sites like to be as close to the equator as they can be -- if you take off to the east, it's free ΔV.

So if the plane was further to the north, it would have been moving faster to the east, from the point of view of the satellite.

Ohhhhh I'm going to throw something ridiculous out so that someone can tell me why it's ridiculous, but it might work? I forgot, the Inmarsat satellites are not completely fixed, they have a few degrees of orbital inclination (1-3º is what I can find roughly). That means that they have some north-south motion over the course of the day, which is roughly

(circumference of geostationary orbit) * 3 degrees / 360 degrees / 12 hours = 16,000 miles per hour

That's a really rough estimate, and probably will drop by a factor of a few in detail, but it's enough to beat out the motion of the aircraft itself. So if I measure the doppler effect of all the aircraft in the north compared to the doppler effect of all the aircraft in the south when, say, the satellite is moving net-southwards, they should be split into a shifted-up in frequency group (all in the south) and a shifted-down group (all in the north). This is a wild guess and I fully expect someone to tell me why I'm wrong, but I figure I should put my neck out there for once.

The rotation of the earth/latitude is still not relevant here, since all points fixed to the ground have zero doppler shift relative to a truly geostationary satellite. The rotational speed you're referring to is relative to an inertial frame, which the geostationary satellite is not.

kiltedtaco, I think your math is wrong. Plugging in numbers I get this for a 3 degree inclination in geosynchronous orbit:

(3 * (35,786 km + radius of earth) * 2 pi) / 360 = 2 207.7 km

Which works out to under 200 kph relative to the surface of the earth. Or is it my math that's wrong?
posted by idlewords at 2:04 PM on March 24, 2014


Rotation of the earth. The closer you are to the equator, the faster the rotational speed.

Yes, but the relative velocity between the two (a satellite in geosynchronous orbit, and a fixed spot on the surface of the earth) is perpendicular to the direction from one to the other, so there's no component of the velocity towards or away from the satellite, and thus no Doppler effect.

Bear in mind that the N/S symmetry is broken by the fact that the region to the north is much more densely populated than the region to the south. I imagine this could have a few consequences:

First, it would not surprise me if the antennas on the satellite were biased northward. If they are, the signal coming "from behind" (south) might be slightly weaker than one at the same distance from the north, and it's possible that you might be able to detect that difference by comparing data from flights going to Europe/Central Asia to those going to Australia.

Second, the north is much more densely covered by primary radar. It's possible that having worked out two symmetric trajectories, they were able to eliminate the northern one based on the fact that it would have had to fly over closely-monitored airspace and yet wasn't detected.

All speculation, of course, but my point is that the situation is perhaps not as ideally symmetric as it would be for a Consider-A-Spherical-Earth.

Yikes, mea culpa on the surface of the Earth not moving w/r/t a GEO sat. Maybe it has to do with the fact that on the southern trajectory the plane would be receding from the satellite since the equator is closer to the satellite than the south pole, and on the northern it would be approaching?
posted by localroger at 2:49 PM on March 24, 2014


A non-zero inclination does give the satellite some velocity with respect to points on the surface of the earth, but I don't think it's a lot (like 250 km/day for a point at 40 degrees south latitude): https://gist.github.com/wiseman/9749487

Yeah, that makes sense, the issue being that the motion of the satellite is mostly tangential to line of sight from the aircraft, since geosynchronous orbit is way way away from the earth compared to reasonable distances along the earth. This is also worse since the aircraft was way off in longitude and moved generally along the tracks of constant satellite elevation angle, again putting less of the satellite's motion along the line of sight. These factors seem to add up to make this infeasible. Damn.

It's going to drive me crazy until they release the details on this determination.

Perhaps interestingly to some, in the video that Slashdot linked, the Inmarsat rep basically echoes the sentiment first penned here by Nelson upthread that it's ridiculous that these planes aren't required to be fitted with position reporters. Considering that that's the industry he's in, when he says it would be relatively inexpensive and simple with existing technology, I think that carries a bit more weight than our speculation here.

Re: the doppler shift
It is being discussed in this forum. A summary of their thinking, as I understand it (and noting that I don't know if this is correct or even plausible, but thought it worth linking):
If the satellite was absolutely fixed then the Doppler shift would be the same irrespective of whether the plane was heading north or south BUT the sun and moon cause a slight - but predictable - wobble in the orbit of the satellite and since that wobble is also N/S that will add a very small but measurable extra value in the existing Doppler shift. If the satellite was heading south at the same time as the plane then the Doppler effect would be squeezed by a tiny bit and the wavelength decreased - ie very slightly blue-shifted. If the satellite was moving north whilst the plane was heading south then the radio wavelength would be stretched - very slightly red shifted. [by user Unixman]

Sun and moon gradually deform the orbit of a satellite in a geostationary orbit, causing it to "wobble" N/S daily unless the satellite spends fuel to correct. Most satellites do this periodically. If you look here List of satellites in geostationary orbit most satellites have "inclination" (wobble amplitude) of less than 0.1 degrees. (If the satellite is left on its own, its inclination is going grow ~1 degree per year.) Fortunately for us, Inmarsat-3 F1 is an old satellite (launched in 1996 and the second oldest Inmarsat satellite in orbit), which means that it must be running out of fuel, which means that its owners are probably trying to conserve fuel and skipping N/S compensation maneuvers. It has inclination of 1.6 degrees. [by user hamster3null]

Further to my speculation, here are two PDFs from Inmarsat showing that indeed, the bandwidth & power distribution for Inmarsat's aviation satellites is not uniformly distributed over the coverage area, but rather concentrated in regions with higher demand: The power appears to drop off considerably in the south Indian Ocean where there aren't spot-beams enhancing it. Perhaps there was a detectable difference in the signal intensity when the plane left high-performance area which would not have occurred if it had gone north?

I'm actually confused why Inmarsat didn't know this answer immediately from the spot beam information. I guess the satellite has one whole-hemisphere antenna which picked up this transmission, and they didn't think that the absence of the transmission from the northern beams was enough evidence that the plane was in the south?

Last Tuesday, user awblain at PPRuNe.org was suggesting precisely this use of (at that time) potentially available doppler frequency shifts of the Inmarsat data packets:

18Mar 19:02
18Mar 21:29

I think what awblain was suggesting was a pretty simple use of the doppler data: as an additional piece of information (radial velocity) to be used in combination with the existing hourly ping position rings in constructing potential flight paths.

If Inmarsat is able to accurately determine --- by doppler shifts in the frequency data --- the radial component (with respect to the satellite) of the plane's velocity, then the direction of the plane is uniquely* specified, assuming: (1) a value of the speed and (2) a position on the ping arc. The set of all ping arcs from 1811UTC (last radar contact) to 0011UTC (last ping), along with the corresponding radial velocity values, could then be used to single out a couple viable paths, i.e., paths connected by a sequence of velocity vectors that lead back to the known point of origin. I guess the data is such that only a southern route is viable.

* There are actually two possible velocity directions at any point on the ping arc, pointing at the same angle from the radially outward direction, but one can probably be immediately excluded due to the known origin of the plane.

Could the missing 0015 UTC transmission be because the airplane was outside the area coverage of the satellite? Someone above has posted the Inmarsat technical pages and there is clearly an area of much lower, perhaps no-coverage at all, near the areas where the plane transmitted at 0011 UTC.
This could explain why there was a signal at 0019 UTC. But what does 'partial' mean? Any clues?
posted by carmina at 6:04 AM on March 25, 2014




The missing ping was actually at 0115 UTC, not 0015 UTC, that is, just over an hour later. I assume this would have been the satellite's next regular check-in. The plane's antenna didn't respond.

The 0019 UTC "partial handshake": No idea. Obviously not the regular hourly ping. All I know is they're trying to figure it out. If it was incomplete, they may be assuming it was aborted transmission from the plane just because there was nothing else in the area. I don't know.

It would obviously be very, very helpful for the searchers if they could figure out the plane hitting the water would have triggered some kind of aborted signal. (I have no idea if that's true or not.)

That "partial handshake" is a very tantalizing incomplete clue. Honestly I think it's irresponsible to release that data without understanding where it came from. It's so tempting to say "oh it must be related to the plane finally crashing", I mean the time lines up! But there's no direct evidence for that being the case.

The thing that's supposed to happen when a plane hits the water is the ELT going off and sending an emergency alert with a position to satellites listening for that signal. I've mentioned this a few times already; it's troubling there was no ELT transmission. There was none for AF447 either, so maybe they just don't work well in the water. Or maybe we got unlucky; the Wikipedia article notes that global coverage is incomplete and that an area can be out of satellite hearing for 2 hours.

You seem to be combining the press and all of the agencies involved into a global "they" that's telling us this but not that. The press has been reporting a lot of random rumors and theories. Inmarsat hasn't been leaking rumors, though Malaysia's MOT hasn't released data from them as completely as we'd like.

The intermediate arcs can be approximately reconstructed from the predicted 450 and 400 knts tracks and the ping times in the Inmarsat data MOT released, so it's not like MOT's actually suppressing it. I think this has to do with how the data and analysis were released: Inmarsat > AAIB > MOT > press release from MOT to the general public. The press release would have been prepared by PR people from info relayed from Inmarsat. The PR people wouldn't have realized how important the intermediate arcs would be to amateurs trying to reconstruct Inmarsat's analysis. (It's still doable, but leaving that out makes it harder.)


Regardless, I agree that "there will be a thousand conspiracy theories" about this. This hijacking seems so senseless. Somebody hijacked an airliner flying from Malaysia to China and either tried to fly it to Antarctica and or bury it in the Indian Ocean where they thought it would never be found? Even if the cockpit voice recorder and flight data recorder are recovered we'll still probably never know why this happened. We'll have a better idea of how it happened, but not why.
posted by nangar at 3:16 PM on March 25, 2014 [4 favorites]


Could the partial handshake at 00:19 UTC be as simple as an OOOI event ("On the ground") initiated by landing sensors, without ACARS being on? Or would someone have had to be alive in the cockpit around that point to switch ACARS back on to register an OOOI event?


> But they still haven't released arcs for every hour. So weird.

Reports are there were 6 complete handshakes ending with the last at 00:11 UTC. I count 8 on the graph (blue line) timed after ACARS 'off'. The first 3 are in quick succession (certainly not hourly), so possibly considered as one arc (giving 6 arcs expected); and the final 2 (22:44 UTC and 00:11 UTC) are 90 odd minutes apart. It's annoying when details are discrepant.

I'd like to see the arcs plotted, too. Explanations of the rapid timing on the first 3 pings and the late timing on the last ping would be interesting, too, given hourly automation has not been the case. Was ACARS possibly switched back on after 22:44 UTC but before 23:44 UTC, preventing the expected hourly handshake around 23:44 UTC? Why the 90 minute gap?

Was the (late) 00:11 UTC ping initiated automatically, or did Inmarsat send off a manual ping at that point?

Something I hadn't seen before (though I may have missed it?) was that apparently the plane had been out of service for a while? From WTOP (local news radio in DC):
As investigators dig into what happened to the plane, a check of publicly available flight records for the missing aircraft identified as MSN 28420 - 9M- MRO, raise a key question about the plane.

The records indicate the plane flew the day before, March 7, from Beijing to Kuala Lumpor. But it appears the plane may have been out of service for an extended period of time prior to its flight on March 7. [...] According to flight log documentation, the plane was possibly out of service for more than a month before its March 7 flight.

Not sure I'd look to WTOP for much beyond the latest water-main breaks & OPM status announcements, but...

We did discuss upthread (#5456043 & #5452997) that 9M-MRO had been involved in a ground-strike accident ~19mos ago which took out a large chunk of a wing tip. Is the "out of service for an extended period of time" distinct from that repair?
posted by Westringia F. at 9:26 PM on March 25, 2014


Yeah, agree that WTOP is not the world's most solid source. It sounds like they're saying it was out of service for a month or so immediately prior to Mar 7, i.e., in Feb of 2014. (If this is true, and they're saying it's from "publicly available records", I don't know why nobody else would be reporting it. So very possibly they are mistaken.)

Hmm... FlightAware's activity log for 9M-MRO [registration/pay-walled] indicates it was flying in Feb 2014: screenshot (via). The screenshot only goes to Nov 2013, but it seems to have been flying rather consistently that whole time.

Whether this is more or less reliable than WTOP, though, who knows.

> Reports are there were 6 complete handshakes ending with the last at 00:11 UTC ...

The burst frequency offset analysis graph released by MOT starts from takeoff. There are ten handshakes total. The first four would be the pilots talking to air traffic control. The remaining six would be pings from the satellite after the transmitter became inactive.

The hourly check-ins from the satellite aren't all at exactly one-hour intervals. The first two and last are after intervals a bit longer than an hour. The middle four pings are at just about one-hour intervals. I don't know why the timing fluctuates. My guess would be that routine pinging of inactive transmitters (to see if they're still on and in range) runs as a background process, with priority given to processing active transmissions. The pattern is consistent with traffic dying after midnight in most of the satellite's service area and then picking up again when it's around 7:00 or 8:00 am in Southeast Asia. (That is, pinging gets delayed when radio traffic using the satellite is heavy.)

> ... with priority given to processing active transmissions.

I feel certain reestablishing communication with MH370 was top priority. ACARS data is slim, automated, independent of pilots talking to ATC, and informs Arrivals Boards. People were running in all directions giving priority to MH370.


> The burst frequency offset analysis graph released by MOT starts from takeoff.

No, it starts at taxiing (or something); take off is the 2nd point on the blue line (12:41am MYT), and all up the blue line joins 12 ordered (time, burst) pairs from taxiing(?) until 08:11 MYT.

The first 3 are easily understood to be properly functioning OOOIs (egs: taxi, take off, climb); the 4th is the "final 1:07am ACARS" we've been hearing about that was carrying FMS data. No arcs required.

Then come the ACARS-off automated hourly handshakes: there are 8 points (remaining), not 6, and they're (really) far from hourly, initially and finally.

The first of the automatic pings would have an expected time: 18:07 UTC (based on last ACARS contact plus an hour). But there was nothing until 20 or so minutes later. Commencing at approximately 18:28 UTC there were 3 rapid fire reciprocated pings: 18:28, 18:29 & 18:30 (say). I'd like that somewhat late rush to establish "handshakes" explained to me, and accept any arcs would be so close together they are as good as one arc.

After that there are 4 well behaved hourly measures (again approximate times): 19:44, 20:44, 21:44, 22:44. These look automated enough. No problems. The system works.

However there is no 23:44 UTC handshake, as expected. None. Not even partial. Could that be because the ACARS was back on? (Yes or no?) That question has an answer.

What initiated the (late and final) 00:11 UTC complete handshake (way off the hourly schedule): automation or ground observers (manually) initiating a handshake? That is a question Inmarsat/UK-AAIB can answer. We have been provided with the time of the last ping -- 08:11am -- from very early in the investigation and have (merely) assumed the 6 arcs are approximately at: 0311am, 0411am, 0511am, 0611am, 0711am, and 0811am MYT -- it's not so.


If the ACARS were switched back on for the last hour (say), can the ground station initiate a manual, not automated, handshake and expect a return? If the answer is yes, then the partial handshake that followed at 00:19 UTC could so easily mark the time of impact, a mere landing sensor sending an OOOI back to ground, on impact.

lukemeister, why no KC135 or KC10 or whatever to provide refueling. They could fly from Perth.

The primary search now is visual -- radar can't really see things floating on the surface unless they just up high enough to get over the waves. So, the search is limited by daylight hours (falling, it's becoming winter in the Southern Hemisphere) and by crew fatigue.

Basically, they're leaving well before dawn, flying out to the site, searching as long as they can. By that time, there isn't much daylight left, so they go home.

Ideally, what you want there is an aircraft carrier, which can stay on station and handle 2-3 hour search flights.

The RAAF does have refueling aircraft, the KC-30A. These are based on Airbus A330s. It can handle both boom and probe/drouge refueling systems, and because this is metafilter, it can also be refueled in flight.

Finally, while it appears that tests were done with refueling P3 Orions, it was never put into service. The RAAF version, the AP-3C, may have that capability, but the US planes don't. It wasn't considered critical because the P-3 already has a 13 hour flight time capability.

The P-8 Poseidon definitely can be refueled -- it doesn't have the endurance of the P-3. Countering that is the speed -- the P-8 is based on a 737 and cruises closer to 500kts IAS, rather than 350kts.

Do we have any reason to think that at the time MH370 was still in the air Inmarsat knew its satellites were in contact with the airplane? Or even knew the plane was missing? My impression is that Inmarsat only realized they could be of help a couple of days after the plane went missing. I've heard nothing to suggest that Inmarsat was trying to communicate with the plane while it was still in flight.

I don't think there's much use right now in trying to figure out what the Inmarsat communications mean beyond what the authorities are telling us. They haven't released enough raw data, and I imagine none of us here have any expertise or knowledge of how those systems work. Somewhere at Inmarsat and some British aviation agency are people who do understand this stuff and have presumably driven the search in the direction it needs to go. I just hope some day a full technical report comes out, because like I've said before the technology here is fascinating.

Remember: Nobody considered this plane missing for quite some time. They had a normal signoff with Malaysian ATC. It wasn't until Vietnamese ATC did get them checking in for a couple of hours that people started to think something was wrong.

*In retrospect*, the timing off the lack of transponder and ACARS broadcasts became important. But at the time, nobody really noticed. This wasn't the only plane in the sky.

So, stop focusing on what ifs an hour after they took off. Nobody, but nobody, even thought there was a problem until several hours passed, and it definitely was noticed when the plane didn't show up in Beijing.

But when that plane turned west? Malaysia didn't care because they'd handed off the flight. Vietnam didn't care because they hadn't gotten the flight yet. Suspicion grew as they didn't check in, but they were heading south to nowhere before anybody really started asking where this plane is.

Here's a question I've idly wondered about, and eriko just reminded me of it. So this plane turned off its transponder and thus was only showing up on plain old radar, without the additional info a transponder gives.

Isn't it *very* unusual for a plane of this size to be flying around without a transponder on? If you're a radar watcher in the Malaysian military (or whatever), does it catch your eye that this plane isn't showing up with transponder data? Is it something that a radar system could/should flag (i.e., mark the plane-blip with a "hey, this thing looks like a commercial airliner but its transponder is off" icon)?

There's quite a bit of nonsense, and little helpful information, in the "How Inmarsat hacked their data" link:

Say the satellite and the plane were both at the same height above the Earth’s surface and the plane was flying in a straight line away from the satellite. This simplified version breaks the problem down into one dimension. If you knew the position and velocity of your satellite and you knew the velocity of the plane, you could easily map the plane’s position over time.

Actually, if the plane were flying directly away from the satellite at a constant relative velocity, then the doppler shift would be constant and you would have no information about the plane (other than its relative velocity). Even if the plane's speed were changing, you would have no information about its position.

...since the satellite is orbiting Earth and the plane is also moving, albeit at a different velocity, this becomes a very complex problem

Actually, as many have said above, the geostationary satellite simplifies the problem since only the plane is moving with respect to the Earth's surface.

China wanted to know exactly what led Mr Najib to announce that the plane had been lost

While I don't think that members of the general public have a right to all of the data (or at least I'm not convinced one way or the other), I think that it's perfectly reasonable for China to expect that Inmarsat and the UK share the full data set with them. In fact, I'm shocked that they have not (if they indeed have not).
posted by pjenks at 3:22 PM on March 26, 2014 [1 favorite]


pjenks, I think what they realized is that becuase of the Earth's curvature, there is a subtle difference in the northbound and southbound Doppler curves, because the plane can't be flying in a straight line. On the northbound path the doppler curve rises more quickly and shallows out as the plane approaches the equator, eventually dipping, forming a convex-up graph; southbound, the curve rises at first only very gradually and then ever more more rapidly as the plane recedes from the equator, and is therefore pulling ever more quckly away from the satellite. This curve eventually crosses the northbound curve but makes a concave-up graph.

The actual doppler data closely match the second graph, and data from other flights were used to confirm that the technique has enough precision to be predictive.

No, we don't. There's probably more indication to believe Inmarsat didn't have anyone monitoring the handshakes as they happened. But I'm poised to jump on reason the moment it surfaces, because for me there is an incoherence. The data doesn't quite match my expectation of hourly automated handshakes in the event of ACARS failure.

By the same measure we look at an early left hand turn away from a direct flight path and think "Ah-ha, there's some deliberate action on someone's part here", I look at the handshake data -- as it's necessarily presented to us -- and think "Ah-ha! Inmarsat manually established 'automated' communication around the time of the last radar fix, and had to reestablish that handshake just prior to impact." Deliberate efforts. Or?

The technology's brilliant, but the theatre is same-same. Inmarsat is a corporate entity, and a long life tells me that ACARS messages aren't the only thing subject to packaging.
posted by de at 3:54 PM on March 26, 2014


Wait, so because Inmarsat said "hourly" but there's one handshake that occurred after 90 minutes, on a handshake system that basically none of us have ever heard of before and whose detailed workings we know almost nothing about, your conclusion is that it's probably a conspiracy?

Dunno about you, kiltedtaco, but I feel capable of taking in the actual data, AND the reasons it varies from the repeatedly stated model: "The analysis follows fresh examination of eight satellite "pings" sent by the aircraft between 1.11am and 8.11am Malaysian time on Saturday 8 March, when it vanished from radar screens" as if it were factual.

And I see no problem wondering how early Malaysian Airlines called on Inmarsat for assistance (if they did). It would be sheer hell, I imagine, watching the 'pings' live from an aircraft gone missing through to the silence of 01:15 UTC.

Not enjoying inconsistencies leaping out at me, and not enjoying my science dumbed down, and having a healthy appreciation of corporate communication just doesn't make me a conspiracy theorist on your say so, kiltedtaco. Damned offensive.

Let's not get into a personal dust-up here.

de, I'm also not totally clear on what you're saying. I understand that the timing of the pings is puzzling, but I'm not understanding why you think this suggests Malaysia or the airline had contacted Inmarsat while the flight was still in the air. As far as I understood (and it's possible I have missed something), Malaysia and the airline... and even Inmarsat itself... did *not* know during the time the plane was in the air that this pinging was happening. So, no manual action on the part of Inmarsat to do anything during that time.

Is there something specific that makes you suspect otherwise? Or just general "something doesn't add up here"?

Also, you mentioned above the possibility of ACARS being turned back on during the last hour of the flight. I'm not fully understanding why you think that would yield the weird last ping. I thought Malaysia Airlines didn't subscribe to the information-sending service that Inmarsat offers, and thus there were only pings... from that, I was taking it that the Inmarsat satellite is not involved in relaying/collecting ACARS transmissions. I thought they were two separate systems, separate both on the plane and on the transmitting and receiving end. Is that wrong?
posted by LobsterMitten at 7:03 PM on March 26, 2014 [1 favorite]


While I know nothing about the system, it seems that it sends (or attempts to send) spontaneous pings for certain important engine events. If the event was "ran out of gas" that could have triggered a ping while the plane was still flying straight and level, having only *just* run out of gas.
posted by localroger at 7:16 PM on March 26, 2014


Only if ACARS was back on, localroger. OOOI event reporting is an ACARS function, else all that is expected of the unit with ACARS-off is "hourly handshakes" back to a ground station (in this case Inmarsat I presume).

Something doesn't add up. I've not found anything explicitly stating when Inmarsat became involved. Maybe I'm missing it. I know they did their corridor and doppler calculations after all data was in, that's no issue. But Inmarsat strikes me as an emergency go-to for Malaysian Airlines in the event of ACARS failure (especially with a lost passenger plane in the air), and I can't have it that the airline sat on its hands until 06:30 MYT wondering what to do with the arrivals board at Beijing.

If Inmarsat can handshake a unit with ACARS-on, then the doppler data (as released to the public in a graph) is, while IMO significantly inconsistent with hourly automation without further explanation, consistent with a troubleshooting scenario of firstly Inmarsat establishing the automatic handshakes (which for some reason hiccoughed), only to lose it again sometime after 06:44 MYT. The 07:44 MYT was a non-event, possible reason being ACARS was on again for the touch down. "Not possible" would satisfy my quandary completely.

An explanation of discrepancies just wouldn't go astray.

There's every chance I'm barking up a wrong tree. Let's leave it drop. (The search has just been called off for the day due to weather deterioration. Perth time: 1:00pm.)
posted by de at 10:00 PM on March 26, 2014




As far as I know, Malaysian Airlines or airlines in general don't have a direct business relationship with Inmarsat. Inmarsat provides satellite services for companies that then provide complete telecommunications packages to other companies. In this case Malaysia Airline was buing that service from SITA. As stated previously, tracking an airplane using this method is completely unprecedented so I there would be no emergency procedure to contact Inmarsat in case of ACARS failure.

A key thing is the airline was reportedly not an Inmarsat customer and was not paying for the data package that allowed satellite uplinks. (Some reports then had Air Malaysia denying that, saying they were customers, I don't know if that discrepancy was resolved.) My guess is the airline didn't even know Inmarsat had any transmissions at all until Inmarsat contacted them.

I don't understand the timing of the published message graph either. But the reason something doesn't add up is because we've only been given a tiny sliver of the information about the transmissions. Which shouldn't surprise anyone, usually this kind of analysis only comes out two years after an incident. And unless one of us is an expert on Inmarsat's data uplinks, we don't really know how that system is supposed to work.

I went back and documented the timeline of the Inmarsat data release. There was several days' delay before the Inmarsat data was taken seriously. Inmarsat told the Malaysian authorities what they knew on March 11 or 12, but it wasn't until March 15 that the data was officially acknowledged. (Inmarsat publically announced the existence of the data on March 14.) Malaysia was already searching to the west as early as March 11, perhaps based on information from military radar. Basically the Inmarsat data is caught up in the same confusion and mess as the rest of the early search. Inmarksat said as much themselves, "I think they have made an honest attempt to try to run a very complex investigation. But people will draw their own conclusions."

I think it's likely that a "handshake" consists of three pings in rapid succession, rather than just one, probably for redundancy in case of radio interference. In cases where the plane was moving in straight line, the frequency offset of the pings would be the same, so they'd be superimposed on the graph.

And, yeah, a more complete explanation by Inmarsat of their data would be helpful.

There is garbage accumulating in the Indian Ocean Gyre, it's even called the Indian Ocean garbage patch. Usually currents break down bigger parts and for example plastic might not even be visible to the naked eye after a while. Plastic trash is not the only thing, over the last few days there were reports of rope, belts and wooden pallets, all of which will take different amounts of time to decompose. But it all starts out as solid pieces that humans throw away (or get lost). It is entirely possible that the satellite pics showed objects completely unrelated to MH370.

New search area (pdf, AMSA). The revised higher speed tracks are really close to the eastern track suggested by the NTSB (shown here, pdf) on which AMSA based it's initial search operations, but have the plane running out of fuel much further north.

From Hishammuddin's press conference:
The international working group included representatives from the UK, namely Inmarsat, AAIB, and Rolls Royce; from China, namely the CAAC and AAID; from the US, namely the NTSB, FAA, and Boeing; as well as the relevant Malaysian authorities.

The group has been working to refine the Inmarsat data, and to analyse it – together with other information, including radar data and aircraft performance assumptions – to narrow the search area.

Information which had already been examined by the investigation was re-examined in light of new evidence drawn from the Inmarsat data analysis.

(Note: The new search area map includes the earlier suggested 400 knot track from Inmarsat's initial burst frequency offset analysis. My understanding from what AMSA's said is that they're no longer using that.)

My understanding of the (new) 400 knots path is that's the speed (required) for the path of best fit factoring in the new data surrounding:

  * available fuel (from review of radar data),
  * aircraft performance,
  * heading implied by Doppler analysis, and
  * distance required to reach the 08:11 arc by 08:11 am.

One path with some drift analysis and 'other tools' as John Young is apt to say.

That's the first sign I've seen that it may not been the pilots. They're well trained to fly at the sweet spot between speed and fuel consumption.

Navy Jet Lacks Key Feature for Flight 370 Search
Navy Says Aircraft 'Currently Not Capable' of Refueling In-Flight

This answers my question from the other night about why the USN P-8A was not refueling in-flight.

The U.S.Navy's newest aircraft is on its first high-profile mission, searching for Malaysia Airlines Flight 370, but the aircraft lacks a key feature that could aid the search for the missing jetliner. The P-8A Poseidon can't refuel in-flight.

The jet, designed for hunting submarines, has been flying daily missions over the Southern Indian Ocean for weeks, now flying roughly 1,150 miles to get to the search area off the coast of western Australia.

The search zone was revised closer to the Australian coast Friday after new estimates of the missing jetliner's possible final location took into account Malaysian military radar which tracked the Boeing 777 flying faster than first thought after it vanished March 8.

While the jet is fitted with an in-flight refueling system to refill its gas tanks without having to land, the aircraft is "currently not capable" of doing so and won't be able to until around 2017, said U.S. Navy spokeswoman Lt. Cmdr. Sarah Flaherty.

I was wondering about the new search site, which is 600+ miles from the original spot. The calculations for the original search site in the southern Indian Ocean took into account the fuel load and assumptions about speed. If the aircraft flew indeed faster how does that match the last ping at 8:11L? If it flew faster and used up the fuel over a shorter distance shouldn't its last ping be at an earlier time? Apparently an aircraft like the B777 could glide for about 50 miles after fuel exhaustion, nowhere near a distance of hundreds of miles that could account for up to an hour (or more, depending on speed) of time.

Somewhat relevant, there's a fascinating post in PPrune by a 777 pilot who got permission to use a real-live 777 simulator and documents what happened when the plane ran out of fuel.

travelwithcats, when investigators say the plane was travelling faster than first estimated they're only talking about that first wayward east to west leg over the top of Malaysia, the leg where radar provided time and location data.

The plane therefore entered the general southbound leg with less fuel, too little to make the distance required to reach the 08:11 arc via the first proposed "south corridor", at any speed. That corridor is now deemed not possible.

It remains a given that at 08:11am the plane was on the 08:11 arc, (so necessarily further up to the east than at first estimated).

All points along the 08:11 arc are equidistant from the satellite, not from the point the plane made its southbound turn. A more south easterly direction provided the plane with a shorter distance to the 08:11 arc, meaning the plane crossed that arc 'higher up' and closer to the west coast Australia. The distance and time provide the estimated 400 knots.

No doubt the new proposed path is a better fit for the direction of travel implied by the Doppler analysis, too.

Great link, amazing post.

I read somewhere, can't find it now, that CNN has booked one of the only available 0 hour publicly rentable 772 simulators, which is in Toronto, solid for weeks so their competitors can't get access to it. Apparently the CNN crew simulated fuel exhaustion over water at FL25 and filmed the entire sequence. (I note the guy who did this on PPrune says he cut off the simulator at FL10 rather than following the oscillations all the way down.) They say they would never broadcast this, of course, because it would be so disturbing. But they're happy to let the world know they ran the program all the way to impact. Yeesh.

"We would like to confirm that the last conversation in the transcript between the air traffic controller and the cockpit is at 0119 (Malaysian Time) and is "Good night Malaysian three seven zero," DCA said in a short statement issued on Monday night.

"The authorities are still doing forensic investigation to determine whether those last words from the cockpit were by the pilot or the co-pilot,'' said the statement.

It was reported earlier that the last words from the flight were "Alright, goodnight", spoken by co-pilot Fariq Abdul Hamid.

Strange, isnt it? I've been checking this thread twice a day for weeks now. The activity here and the water cooler chatter irl really dropped off when they found satellite images and decided to focus on the southern corridor - the public feeling seems to be that the case is more or less solved. But the satellite images and extensive boat and plane searches have found nothing actually related to the craft - it's all just flotsam and other ocean junk. Except for more speculation based on closer and closer analysis of the data, we don't conclusively know that much more than we did last week. It really does seem like they will never find anything and that we will just assume it crashed into the southern Indian ocean. And as far as I can tell, we still don't have any conclusive idea of why the plane diverted to a new course and eventually disappeared.

I am still unsatisfied and unsettled and have very little hope of ever fully finding out what happened.

AF447 was eventually found by sidescan sonar. Surface debris has had time to travel very far and sink far from the crash site due to the rough seas and strong currents; the actual wreck should be on the bottom somewhere near the possible tracks identified by the satellite clues. It may take a few years but I doubt they'll give up and I think they will eventually find it.

I agree it's going to be very hard to ever find the plane. The black box sonic pings seemed to be the best bet but the battery only lasts ~30 days, time is quickly running out. After that stops working, barring some classified technology I don't see how they're going to find the plane. It's likely 9000 feet underwater, and at best we know where it is within a .. 500 mile radius? Some impossibly large space. And unfortunately it's not like AF447. That plane's wreckage was found on the water within a couple of days of the crash (I believe aided by ACARS data), greatly narrowing down the location. And even then it took nearly two years to find stuff because of the depth.

The Royal Aeronautical Society has a post on theories about what happened to MH370.
This week, the RAeS Flight Operations Group (FOG) held a two-day conference ... which included speakers representing pilots, airlines, manufacturers and regulators. We took the opportunity to ask a selection of these highly experienced and extremely knowledgeable speakers some questions as to what might have happened aboard the missing 777. A summary of their amalgamated answers appears below:

....

One technical expert highlighted the fact that, for every plausible scenario suggested so far as to what might have happened to MH370, there was at least one contradictory statement.
Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO), which has been assisting AMSA in current trackng for this search, has posted a video of simulated debris drift in the Indian Ocean from 2009 covering the current and previous search areas. (via)


I'm pessimistic about the chances of the plane being found. I can deal with the idea that it's just this bizarre and inexplicable thing that happened and just get fascinated with the technical details, but for families of the passengers and crew and their friends, the idea that they may never know what happened has to be really hard to deal with.

what is the actual source for this transcript?

I don't know for certain, but I assume from a ground station recording of the ATC conversation. At least in the US, ATC radio traffic is always recorded and kept for weeks. If anything unusual happens a copy is made for the record. (There's also amateur-made recordings with spotty coverage, see LiveATC.) I'd assume all international ATC radio communication has some sort of recording infrastructure, it'd be crazy not to.

What I can't understand is how there was ever any ambiguity what those last communications were. The originally reported words came from an official Malaysian briefing. It's terribly unprofessional to brief the world with incorrect information. It's not just a tiny difference, either; the new words "Good night Malaysian three seven zero" include the airplane's call sign and sound way more professional than the initial reports. In the end it's probably not significant, but it sure does reinforce the idea the Malaysian authorities don't really know how to handle communications in this kind of intense international event.

I read through that transcript and it seems entirely ordinary to me. (I'm a pilot, but only tiny planes in the US; no expertise with commercial flights or international ATC.) What's missing is information on who was talking on the plane. Presumably they've identified the voices by now?

If you were really looking for straws to grasp, you could read something in to how the plane says "Morning" in greeting to Lumpur Radar at 12:46:51 and then says "Good Night" when signing off at 01:19:29. But it's the middle of the night so it's ambiguous. At least in American English, "Morning" is more of a "hello" and "Good Night" is more of a "goodbye", it seems ordinary enough to me.

I like that Lumpur Approach greeted the plane with selamat pagi. That's technically not correct (not in English) but it's the common sort of casual communication you'd expect in routine ATC.

I can't understand how it could possibly happen. The very first reports, the very first information that indicated something unusual was going on, was that the pilot hadn't signed off with his call sign, hadn't acknowledged information regarding the Vietnamese ATC he had to talk to next, and that this was somehow weird. So much consideration in the past weeks has been driven by the idea that the pilot/co-pilot didn't communicate with ATC in the proper way before communication stopped.

And your point regarding the Malaysian authorities, the same one as I have raised before, explains so much. The Malaysian authorities are used to dealing with a placated media that they control. They really, really aren't used to dealing with actual journalists who want actual, real, unbiased, useful information. Unfortunately, I'm pretty sure that when this is finally all over, the Malaysian government is just going to breathe a sign of relief and say "good, finally it's over, we can get back to doing what we're good at, and dealing with journalists via Barisan National press releases!".

Oh, entirely written into the Abbott government's good neighbour JACC initiative. Ex-Australian defence boss reportedly to head MH370 search; and the rest:
Sydney's Daily Telegraph said Houston's brief was to not only lead the search but also coordinate the often delicate diplomatic contacts with search partners in Malaysia, China, the United States, Japan, South Korea and New Zealand.

He will also ensure the joint agency provides a single point where the families of the 239 people who were onboard the flight when it disappeared on March 8 can obtain information, the newspaper reported.

It said services available to the families, most of whom are Chinese, would include up-to-date information and travel assistance, including visa services, accommodation advice, interpreter services and counselling.
Somewhere I did read that Malaysia was also setting up shop in Perth to continue councelling services to relatives of the passengers and crew lost on flight MH370. Houston, we could still have a problem.

In the absence of any search news, some continue to verify/reconstruct the Inmarsat ping-doppler conclusions. One notable "reconstructor" is space scientist Duncan Steel who has done a series of careful analyses of the published data (a meta-post to all of his prior postings on the subject was posted today). These include:

28Mar: Error analysis of ping rings (including timing error, satellite position and earth shape)

1Apr: Analysis of Inmarsat doppler data

and

2Apr: "The Inmarsat-3F1 Doppler Data Do Not Exclude a Northerly Flight Path for MH370"

He has been assisted in his newest postings by engineer Mike Exner, who has apparently calibrated the published "burst frequency offset" doppler data to get the absolute line-of-sight velocities for the plane.

Perhaps most interesting is a throwaway line from yesterday's post:
Mike only had [one ping ring] to use. We now have others (which I will be posting on this webpage in a while).

Seems from the comments that the new ping ring data comes from a nice analysis on reddit of the published constant speed paths.
posted by pjenks at 7:05 AM on April 4, 2014


Those links are fascinating, pjenks, but it looks like they're all working from the limited published data and trying to reverse engineer more data points. That's fraught with statistical peril. I'm particularly skeptical of any claims that the reverse engineer brigade on Reddit can somehow divine a more accurate prediction than the Inmarsat and SAR folks with access to all the real data.

Here's a bit of new news: Malaysia Airlines might not have done battery maintenance on the black box pingers. It's ambiguous and probably doesn't make a big difference anyway, but we may only have had 20-25 days instead of 30. We're on day 28 now. These battery lifespans aren't total cutoffs, the signal just starts fading out.
posted by Nelson at 9:05 AM on April 4, 2014


Nelson, Yes, the reddit analysis is a reverse-engineer of the constant-speed flight path data points, but I think that, thus far, the doppler analyses only use published data points. They are simply drawing possible flight paths and then checking whether it matches the doppler offsets plotted by Inmarsat (which seems to be exactly what Inmarsat did, though I assume they looked at an exhaustive sample of "possible" paths).

I'm not as skeptical of the reddit reverse-engineering (it's important to note that they are not actually making claims on direction or the fate of the plane... they are just trying to extract the unpublished ping rings). They take the two published constant-speed paths, which I think are both great circles, and then do a best fit to get the radii of ping rings at the times of the prior pings (going back 1.5h, 2.5h, ... along each constant-speed path). There's certainly error in the analysis, but it sounds like a very reasonable/straightforward approach.

I have not yet seen an analysis which combines reverse-engineered ping rings and the doppler data. I think one could actually predict likely paths (rather than verify random paths) under various speed assumptions. Perhaps that is what Steele is doing now.

If the pilot (or whomever was at the controls assuming a criminal act) deliberately put the plane into the water as gently as possible at the limit of fuel how intact could it remain on impact?

Well that could be great news about the ping! Or it could be nothing.

Here's a great example of how bad news reporting is and why it's dangerous to try to read too much in reported details. Here's the English Xinhua report which is the source of the "pulse signal detected" news. AP picked that up and republished the finding; here's NPRs copy of the AP story at 9:33AM and here's AP's copy of their story at 9:43AM. Compare these three quotes from the articles:
Chinese patrol ship Haixun 01, searching for the missing Malaysian passenger jet MH370, detected a pulse signal with a frequency of 37.5kHz per second in southern Indian Ocean waters Saturday. A black box detector deployed by the Haixun 01 picked up the signal at around 25 degrees south latitude and 101 degrees east longtitude.

A black box detector deployed by the ship, Haixun 01, picked up a signal at 37.5Hz per second at around 25 degrees south latitude and 101 degrees east longitude, Xinhua said.

Xinhua said a black box detector deployed by the ship, Haixun 01, picked up a signal at 37.5 kilohertz (cycles per second), the same frequency emitted by flight data recorders.
It's a very simple fact they're trying to report, the frequency 37.5kHz. The source Chinese article calls it "per second" which is nonsensical but at least the correct number. The AP rewrite of the story then misquotes the number as 37.5Hz, as if the k didn't matter, and repeats the "per second" nonsense. The corrected AP version reports the frequency correctly but then omits the latitude and longitude from the entire article.

It's illiterate reporting, a game of telephone played by people who don't understand basic scientific measurements.

Hours after the report, the Australian chief coordinator of the Indian Ocean search, retired Air Chief Marshall Angus Houston, said “the characteristics reported are consistent with the aircraft black box.” He also noted that white objects had been spotted floating in the water about 56 miles from the area where the sounds were heard.

But he urged caution, saying the reports could not be immediately verified -- a sentiment echoed by Malaysian and Chinese officials. [...] False alerts can be triggered by sea life, including whales, or by noise from ships. An alert sounded on the British Royal Navy vessel HMS Echo last week turned out to be false, according to the Australians.

A senior Malaysian government source told CNN that Flight 370 flew around Indonesian airspace after it dropped off Malaysian military radar. The plane may have been intentionally taken along a route designed to avoid radar detection, the source said.

The conclusion was reached by investigators after reviewing radar track data from neighbouring countries, CNN reported.


So far, it's just CNN reporting this with the Straits Times (Singapore) reprinting it.

Meanwhile, the Malaysian police have been examining all the closed-circuit tv footage from KLIA, the toll plaza on the way to the airport, and the road in between and have been able to track every passenger's arrival to the departure gate:

Criminal investigators looking into the possibility of foul play by those on missing Malaysia Airlines flight MH370 may have found some leads to narrow down their probe... Police on Wednesday said they had "obtained some clues" on what might have happened to the flight, based on the statements recorded from more than 170 people...

It was the same day that they cleared all 227 passengers of the flight. They, however, did not give the same clearance to the aircraft's crew.

Their probe had focused on four possible areas: hijack, sabotage personal problems and psychological problems.

Inspector-General of Police Tan Sri Khalid Abu Bakar had said police were looking at the crew of the flight, as the main "subjects of investigations".


per the Straits Times. The article states that this is a separate investigation from the team that is searching for the airplane.

Guardan: Another unconfirmed signal has been detected in a different area. A British ship is headed to the Haixun 01's location.
The third signal was detected on Sunday morning by the Australian navy ship Ocean Shield, located around 300 nautical miles away from the Chinese ship.

Houston said he did not know at this stage whether the acoustic signal detected by Ocean Shield was 37.5kHz, the frequency emitted by a black box locator beacon, but the lead was “something that needs to be investigated”.

The HMS Echo, a British navy ship carrying a towed pinger locator, was being sent to assist Haixun 01 but would take 14 hours to arrive at the rendezvous, said Commodore Peter Leavy of the Australian navy.

The Ocean Shield would further investigate the signal in its own area before heading to join the Haixun 01 and Echo, Leavy said.

I admit to being confused about the difference between vessels which tow a ping detector below them and those like the Haixun 01. The former seems to be slow moving with a limited range; the latter seems to be able to detect a signal from a long way off (at least in terms of getting a bearing and frequency). Why have both?

Transcript of [JACC] press conference, 6 April
Angus Houston introduced 'acoustic events' to the search vernacular; mentioned a change to plane speed estimate:
Today, the international investigative team has this morning advised of a correction to the satellite data that has been used to calculate the probable flight path of MH370. The correction arises from new information about the state of the satellite itself when it received transmissions from MH370 during its flight. The effects of the correction is to raise the priority for searching the southern component of the existing search area ahead of the northern component.
And IMO Houston was annoyed that word of acoustic events had leaked; and was not all that prepared to be facing questions. Tomorrow's active search area(s) will be shifted to where Haixun 01 just happens to be, because Inmarsat.

Just to complicate matters, also this morning Ocean Shield reported an acoustic event miles away from Haixun 01's detections, so Ocean Shield will not be steaming to the new search site.

Unlike AMSA & ATSB, JACC is pure politics, so it's difficult to know what to think.

JACC news conference: The Ocean Shield may have picked up the real thing (usual notes of caution). JACC has updated their media report with a map showing the underwater search area, the arc of the partial handshake, and location of signals picked up by the Ocean Shield and the Haixun 01.

from nangar's press conference link: ...[Ocean Shield] has detected signals consistent with those emitted by aircraft black boxes. Two separate signal detections have occurred within the northern part of the defined search area. The first detection was held for approx 2 hrs and 20 minutes. The ship then lost contact before conducting a turn and attempting to reacquire a signal. The second detection on the return leg was held for approx 13 minutes. On this occasion two distinct pinger returns were audible. Significantly this would be consistent with transmissions from both the Flight Data Recorder and the Cockpit Voice Recorder...

To quote Winston Churchill: Now this is not the end. It is not even the beginning of the end. But it is, perhaps, the end of the beginning.

This thread is due to close soon. I hope someone opens a new one because we're clearly not done with this story.

What am I leaving out? It might be good to include more news media links. And it might make sense to wait a bit and see if the search teams locate any wreckage.

What am I leaving out?

Just how measured Australian authorities are with the release of information. Houston is quietly popping corks (and probably over being annoyed at losing the tasking of Echo to Haixun 01's press leak).

This is the first time a map of the subsurface search area has been released; and still no mention of HMS Tireless.

This thread dies approximately at the same time as the batteries powering the pingers.

That is an eerie, creepy thought.

See you when HMS Tireless surfaces; Houston mentioned 'a few days'. Tireless arrived 5 days ago and there's not been a peep since.

We'll find it. Retrieval may be a mother (but only of invention).
