Government Releases Detailed Information on 9/11 Crashes Complete Air-Ground Transcripts of Hijacked 9/11 Flight Recordings Declassified Washington, DC - August 11, 2006 - The National Transportation Safety Board (NTSB) this week released full transcripts of the air traffic control recordings from the four flights hijacked on September 11, 2001, and meticulous Flight Path Studies for three of the flights, in response to a Freedom of Information request by the National Security Archive. The studies provide the most detailed technical information available to date related to the hijackings, and the transcripts of the aircraft-to-ground communications are the first complete government disclosure of each flight's air traffic control recordings.

The UAL93 flight data recorder info is way too technical, maybe someone with aviation knowledge can make sense of it.

However, I thought there was also a cockpit voice recorder from that flight that was recovered but it's not included here. Was that ever released?

It's actually refreshingly honest. Five minutes in, one of the controllers reminds the robot pilots not to get too close to WTC 7, since it's going to be simultaneously brought down by a controlled demolition.

Somebody say "conspira... " er,
WTC Steel Returns! Or in reality it never left.
And you thought all the 9/11 WTC wreckage was swept up in eight months and sent to be smelted in foreign countries or secret places in our own strange land, right? And that the rest of the rubble was buried in Fresh Kills (appropriate name), Staten Island. So did I. But now it turns out last remains of the Towers are being stored in an 80,000-square-foot hangar at JFK International Airport in New York. Ain't that a kick in the head?

The previous fact comes from the fifth paragraph of an article Fragments of Twin Towers may return to Coatesville by Jennifer Miller at DailyLocal.com. It's a story about Coatesville, Pennsylvania, wanting to get some WTC steel "trees" for the future National Iron & Steel Heritage Museum, to be built in the city's Lukens National Historic District. The Graystone Society is the group propelling the museum project. Well, how nice.

Scot Huston, a "direct" descendant of the Luken family, president of the Graystone Society, and Gene DiOrio, Graystone Society vice president, traveled to that JFK hangar to meet with New York Port Authority officials about bringing some of the remnants back to Coatesville. That's even sweeter.

But how about giving some steel "trees" to some 9-11 scientists and engineers? To see if the steel is still strong or if there is any evidence of explosives on them or to test their melting points. I mean since NYPA officials are accommodating these Coatesville folks, let's remind them there is a 9-11 Truth Movement concerned with all these little details in little ole New York City, where the tragedy occurred. And this movement lives around the nation and the world as well.

So to me, further sharing of the "trees" for forensic research seems like a modest proposal, especially in light of some of the darker purposes for which the wreckage is being shared. Trust me. Nothing's ever simple concerning 9-11.

Warship built out of Twin Towers Wreckage
Thats amazing that the steel is sitting in hangars at JFK. If true...I say we test it for thermite traces and other explosive chemicals... It all makes sense. They spread the reports that 'all' the steel was shipped by barge to Shanghai just so no one would bug them for it to examine for evidence.

But you know maniacal serial killers...they always want to keep a few 'trophy's' of their kills as talismans.

Weird how UA 175 reports to the tower that they heard the accidental transmission by the terrorists on UA 11.

I think Flight 93 won't be released because you probably can hear victims fighting in the cockpit and they want to protect privacy.

The interesting stuff in the UAL93 flight recorder data isn't until page 17, which plots out all the data on a combined chart. Everything looks about normal until a blip at 9:28, where the plane takes a bit of a downward dip, but the autopilot was on, so it was probably just normal chop.

This is all from page 17, I know very little about flight 93 and I haven't cross-referenced with anything.

If I'm reading this right, the autopilot is on most of the time. All altitudes are pressure altitude, approximately feet above sea level.

Beginning at 9:34, however, it's switched off for about 30 seconds, the plane pitches up a bit and banks a little to the right, and it gets a bit rough (vertical acceleration shows some sudden shakiness.)

AP is reactivated, and the plane pitches upward to about 10 degrees, banking left 15 degrees, which brings the plane up from ~35000 feet and a heading of ~270 (due west) to ~40000 feet, heading 120 (southeast), over five minutes, which brings us to 9:39.

Note here that the service ceiling of a Boeing 757 is 41000 feet, and a service ceiling is about where it's going to take you a seriously long time to climb any higher.

Between 9:39 and 9:40, the plane is made straight and level. At 9:41, the engines are brought down to 50% of full, and the plane starts downward.

From 9:41 to 9:45, the plane is descending from ~41000 feet to ~20000 feet. (Which is about 5000 feet per minute, which is pretty serious.) The plane levels sharply at 20000 feet at 9:45, bringing the airspeed down from about 370 knots to 270 knots over the next minute or so.

There's some very shaky moments from 9:45 to 9:47, vertical acceleration looks like they're experiencing some pretty severe up-and-downs, although no stronger than previous turbulence. The autopilot is switched on and off for a second, and the plane starts back down (9:47).

It's a very smooth descent, under autopilot; the speed is maintained at 270 knots until 9:52 (15000 feet), then 300 knots. The descent rate is about normal for a jet. 10000 feet is passed at 9:55.

Impact is just before 9:58.

It seems worth noting that various disparate parts of the government can't give a coherent account of what was done and said on 9/11, not to mention other amazing coincidences that lead up to the day's events.

It takes a declassification request to get transcripts five years after the fact, and people wonder why there are conspiracy theories? Rational observers can make up their own minds, but regardless of one's views, it is clear the government has done itself a major disservice with its attitude of secrecy.

(I'm not sure if anyone cares, but this and the previous comment were a response to Pastabagel's "The UAL93 flight data recorder info is way too technical, maybe someone with aviation knowledge can make sense of it." I found it interesting, anyway, so I figure I should put the analysis, such as it is, somewhere. I am not a licensed pilot, btw.

After checking more pages, I've verified that I was reading it right, at least in that autopilot was used for all of UAL93's maneuvers. Page 29 has autopilot settings details:

Around 9:35, A/P was set to: ~120 degrees heading, 15000 feet altitude, +1000 feet per minute vertical speed. Then, altitude, heading, and vertical speed hold were activated. It looks as though V/S (Vertical Speed) Hold overrides altitude, as the plane was climbing, and I guess they were too busy to notice.

At around 9:36, autopilot speed was set to about 350 knots, presumably the maximum, and I don't think it had any effect.

(9:39) Once the plane got to 41000 feet and was basically unable to climb anymore, they flipped off V/S Hold and altitude hold, figured it out, apparently, and set the A/P to -3500 or so fpm vertical speed, 190 knots, reactivated it, and let it go. Again, I don't think the speed had any effect.

The V/S was then set to 0 at about 9:46, and heading hold was activated. The V/S Hold was toggled on and off a couple of times (~9:46:30, ~9:48:30). The autopilot speed is gradually turned up, eventually settling at ~250 knots. The altitude was set to 5000 at 9:48 (but remember it's overrided by V/S); the V/S setting is only measured once a minute, but it is set to a couple things over that time.

Eventually, (9:50) it's stable at -1000 feet per minute, and set active. A minute later or so, the A/P speed setting is turned up to 300 knots.

Blacklite, if you cross reference this to the transcript from the voice recorder, it fits - eg, at 9.59 the fight begins and the plane begins its erratic manuevers.

Depends on how the tests were done and documented. Alas, the collapse location was not treated as a crime scene, so it is hard to be able to say 'this beam was found in the condition you now see it at place X and damage Y was done at place Z or in transit.' And that would be the weasling out.

In the month following last year's 7/7 London bombings, Vice President Dick Cheney is reported to have instructed USSTRATCOM to draw up a contingency plan "to be employed in response to another 9/11-type terrorist attack on the United States". Implied in the contingency plan was the certainty that Iran would be behind a Second 9/11.

Thermite leaves aluminum oxide and iron. Both would be completely normal to find in any office building

Not in the concentration you get in a thermite reaction. The very large lump of very pure iron you get out of the reaction -- the one often coated in slag from lesser materials near the reaction is a dramatic hint that a normal fire wasn't what happened there.

Of course, cutting a horizontal beam with thermite is hard. It tends to melt through whatever is holding it next to the beam.
posted by eriko at 4:25 PM on August 11, 2006


Whether or not there was a conspiracy behind the original events, the undisputed facts are the really scary and disgusting parts:

Deprioritizing terrorism while planning (remember, before 9/11) to invade Iraq
Ignoring the threats (remember "Bin Laden determined to strike US"?)
Taking the longest vacation in the history of the office of the Presidency prior to the attacks
Using the attacks as an excuse to invade a country which was absolutely not involved in any way
Lying to congress (and when the truth became apparent to all, congress makes not a peep. Cue founding fathers spinning in graves)

These events are really an indictment of the two party system. This sports team mentality we have in politics is doing nothing to improve the country, instead it's just pitting people against each other and making problems worse. The democrats, had they been in control of congress and had the president been a democrat, would've probably let their president slide just like the republicans have. The whole lot of them should be thrown out on their ears, and we start over from scratch. Every incumbent, both (R) and (D), deserves to lose.

From the way the data looks, I actually think that the terrorists were going to give manual flight a try, initially, and it didn't work out very well, so they just turned on A/P. Although, like I mentioned, they screwed up with the vertical speed hold. I don't think they had very much training at all, really, just enough to know the basics and know how to work the A/P. (Which doesn't really take that much.) I think they were under the impression that you had to flick it on and off to change some of the settings, and/or they were just trying whatever they could think of. When you switch A/P off, there's a big warning light and a noise, so that's probably why it goes immediately back on again (except for that first time where it was off for about a full minute.)
