You may have heard how sounds travel farther during a temperature inversion
, when air near the ground is cooler than the air above. But do you know how this phenomenon is related to the 1947 UFO crash in Roswell, New Mexico? [more inside]

"Of all the men known to have boarded the Hunley, indeed, only about half a dozen escaped death in her iron belly–yet McClintock himself survived the war, and one of the keys to understanding the events of 1879 is to establish why he did so."
Scam artists, war profiteers, double agents, possibly faked deaths, and the precursors to the IRA are all tied together by the designers and builders of the first combat submarine to sink a warship,
in the American Civil War.

In 1820–or so he claimed–he was offered the sum of £40,000 [equivalent to $3 million now] to rescue the emperor Napoleon from bleak exile on the island of St. Helena. This escape was to be effected in an incredible way–down a sheer cliff, using a bosun’s chair, to a pair of primitive submarines
waiting off shore.

Relying on depth to avoid detection is a submarine's greatest ability, so the shallow water of our nation's rivers doesn't seem to work within a sub's advantages (just don't tell Kentucky
). During WWII, however, the waterways of North America were exactly what U.S. submarines needed in order to avoid detection. The shipyards of Manitowoc, Wisconsin produced submarines
for the war effort, but getting them to the sea proved difficult. German U-Boats waited outside the St Lawrence
to torpedo any ships leaving the Great Lakes for the Atlantic. The submarines, instead, went cross-country
- over two dozen subs were towed through the Heartland during WWII over several years, making their way from the Great Lakes, through Illinois and passing Peoria
via the Illinois River, then entering the Mississippi River and past Cape Girardeau
, where they entered the Gulf of Mexico at New Orleans. Four of the subs were lost in battle, the rest scrapped over the next fifty years, and none ever saw St Louis again.

"Few Victorian inventions have the grace and charm of the Ictíneo
, the series of two wooden submarines
built by Narcís Monturiol i Estarrol
in the second half of the nineteenth century ... The thinking at the time was that it was almost impossible to run a steam engine underwater because it would use up all the oxygen and convert the inside of the ship into an oven. To overcome this, Monturiol invented a chemical furnace based on a reaction between potassium chlorate, zinc and manganese dioxide - a process that produced enough heat to boil water to run the steam engine. To complement this ingenuity, the reaction gave off oxygen as a by-product ... While his competitors devised submarines for military purposes, Monturiol had alternative ambitions. The man was a communist, a revolutionary and a utopian who regarded his invention as a way of improving the life of the working class ... "

The Letter of Last Resort. At this very moment, miles beneath the surface of the ocean, there is a British nuclear submarine carrying powerful ICBMs ... there is a safe attached to a control room floor. Inside that, there is an inner safe. And inside that sits a letter. It is addressed to the submarine commander and it is from the Prime Minister. In that letter, Gordon Brown conveys the most awesome decision of his political career ... and none of us is ever likely to know what he decided.

Canal Zone Images
is a collection of stories and images about the Panama Canal Zone. Did you know that the construction workers were paid in gold and silver
('spiggoty' dollars)? "Paper money was not used on the pay car at all. In the first place, there was always a danger of its blowing away, and in the second place paper money in the hands of negro workmen soon assumed a most unsanitary condition." [more inside]

I think the trouble is telling them what the project is about. People think you are mad. Once I started telling people it was for “an oil tank”, they started to take me seriously. Guernsey Submarine
documents the building of a homemade submersible. You can also watch another K-350
in action, read
about how to design them, or buy plans
, if you're truly inspired.

It's out there someplace.
The NOAA and the Office of Naval Research are about to start searching for the U.S. Navy's first submarine, which went to the bottom of the Atlantic off Cape Hatteras in 1863. Unlike the Confederacy's CSS Hunley
, the USS Alligator
never saw action, but it's historically significant nonetheless. Perhaps it can be recovered, as its Rebel cousin

In 20,000 Leagues Under the Sea, Jules Verne predicted that submarines would go to the South Pole and be nuclear powered. Leonardo da Vinci, the Florentine Renaissance inventor and artist, developed plans for an underwater warship but kept them secret. He was afraid that it would make war even more frightful than it already was. Get the facts

Washington state and the Bangor submarine base
are all also in a state of heightened security. I drove past Subase Bangor and they are in Condition Delta, which is when every person who enters the base is physically searched, as well as their car. As a former member of the US Submarine Service I can tell you from first hand knowledge that the military is being scrambled right now to prepare for heightened security along the coastlines of the US.
The entire Puget Sound is reeling from the tragic news... malls are closing, the WA state ferry service is no longer transporting cars, federal buildings are being closed, and major structures such as the Space Needle are being evacuated.

They're dead. They're all dead.
Buf if the rear section has been flooded with high pressure water, and if the British mini-sub latches on and opens the hatch, the mini-sub will instantly fill with water and the entire crew of the mini-sub will die. Oh, my God. Oh, my God. Now I hope they can't
