What I want to know is, for a dive of 20 minutes bottom time to 35,000 feet, what’s the best gas mixture? What’s the decompression / ascent profile, using US Navy parameters? ---

I can’t take the PRESSURE! Which is pretty extreme at that depth, even it is only twenty minutes. btw, the entire dive took much, much longer. ---

It was a research project but probably not for what you think. They went there to test their new clothing invention. The resulting [tench coat](http://www.nextag.com/All~trench+coatz0zB4zmainz5-htm) earned them millions and is now found all over the world in all styles and colors.

You’ve misspelled that, but I’m pretty sure you meant the Dench Coat, which is originally English but has grown quite popular here in the States over the last ten years. ---

Wow, according to the pressure calculator at this site [www.1728.com/convpres.htm](http://www.1728.com/convpres.htm) the water pressure at 35,813 feet is 15,526 pounds per square inch !!! Also, forgive the thread hijack but the OP suggests that the Seaview of “Voyage to the Bottom of the Sea” _never_ visited the Marianas Trench. So, in a sense, the title of that movie / TV show was rather deceptive. Not many people know that. ---

This indicates that if you took Everest, which is 28,000 feet tall, used a piece of piano wire to slice it from the earth’s surface (ask your parent or guardian to assist), then upended it in Mariana’s salty trench, you’d still have lots of room left to erect a lot of 40-story buildings. ---

> [@racer72](#): > > I wonder if GW thought of looking in Mariana’s Trench for the WMD? Um, no. Remember, man has visited the deepest part of the worlds oceans, Challenger Deep in the Marianas Trench, just once. In 1960. For 20 minutes. [Cite](http://en.wikipedia.org/wiki/Marianas_Trench). Saddam Hussein was only twenty-something when this happened and not at the time the leader of the Iraq under Saddam’s regime. Therefore, if man has visited the deepest part of the worlds oceans, Challenger Deep in the Marianas Trench, just once, in 1960, for 20 minutes ([Cite](http://en.wikipedia.org/wiki/Marianas_Trench)), that trip would not have involved Iraq. Hence there would be no point to looking in Challenger Deep in the Marianas Trench (the deepest part of the ocean, which has been visited by man only once, in 1960, for 20 minutes; [Cite](http://en.wikipedia.org/wiki/Marianas_Trench)) for WMD since no man has been there since 1960, and even then for only 20 minutes.

OR, room on top of Everest for 1,465 girls who attended the Yale prom, standing one on top of the other (assuming average height of 5’4" [cite](http://www.wonderquest.com/size-women-us.htm)), though the top one would be sticking 4" out of the water (but this four-inch protrusion might be easily hidden by a pile of salt…or the moon). Of course, if this was in 1960, there’d be room for a 24-pack more of girls who attended the Yale prom. This is not because Everest was shorter then, but that the average female was ([cite](http://www.dental.am/more.php?id=3951_0_1_0_C)). ---

But, and not many people know this, if you tool all the yeast form the infections of all the girls who have attended the Yale prom since 1960 (for at least 20 minutes), and used it to bake pretzels, all the salt in the world’s oceans would not make the pretzels any less nasty. But a good 300 hours on the moon, under a 40 story crust of salt might be a good start… ---

That would be important information, but, most vacuums are not nearly 299,792,458 meters long. I have several and am practically an expert in vacuumology. Most are at best 1-2 meters, including all attachments. Frankly I think the light would get bored in a vacuum after a few seconds. ---
