So thats whats wrong with you....

No, I just don't give a Sh@t... I've been told that is my problem

you are a honey badger, which isn't really a problem

Honey Badgers are way more badass than Geek.

Bad ass is a state of mind, and I'm the baddest most awsomest, coolest, brilliant, good looking one in mine...... oh, and humble too

gags and vomits on putrid humility

Wow. That is a very illustrative video. Thanks for posting, Geek, even if you don't give a $h@t!

FYI - anyone can try this for themselves in the US. I consider it highly advisable for any rebreather divers out there.

The FAA, via it's civil aeromedical branch (CAMI) offers this training for free in Oklahoma City, or at nominal cost at a bunch of air force bases...Spokane is the closest to Seattle. Last time I went for it, I think it was something like $50 - may have gone up a little, but it's still dirt cheap. It's basically a full day of classroom, with a chamber ride in the end.

The only requirement is you have an FAA third-class medical or better, which you can get from an aviation medical examiner for about $75. If you're not actually a pilot, it comes with a student pilot certificate for free You can actually take the class without the medical, but you can't ride in the chamber.

Seriously good training; I did it for a high-altitude endorsement a number of years back, so I could fly pressurized aircraft up in the flight levels, but I think I actually got more out of it with relation to the rebreather diving...

I'll be darned. I never heard about that before. Very cool.

Cam, you're just full of surprises!

After that anyone doubt the wisdom of following the Flight Attendant's briefing to "...put on your own mask first before assisting others."?

Especially since, as I recall, you are already at 8000' PA before the decompression.

What the flight attendants don't tell you:

• Your actual time of useful consciousness is about 10 seconds at 40,000' after an explosive decompression (if it's gradual, you might get double that...if you're lucky). Hope you actually are lucid enough to remember what you're doing
• Your ear drums are probably bloody, blown out, and in pain
• The pilot is diving the plane as rapidly as possible to get to a lower altitude, so your stomach is back up at 40,000'...
• Everyone around you is going to be acting like a panicked moron

What she really ought to say is, "grab a mask and good luck," but that's not particularly reassuring to the general public...

Thats depressing but really funny at the same time....

Usually domestic airlines fly plus or minus a bit around 35,000 feet so you only have about 27,000 feet of altitude differential. (I'll leave it to the other folks to calculate the pressure differential). Then, although decompressions do happen rapid decompressions are exceedinly rare. Big, big difference between a Decompression and a Rapid/Explosive Decompression. One is very survivable for most everyone. Last one I personally know about no one, crew or passengers, was injured. The Rapid Decompression may cause some injuries, especially if there is a respiratory problem, ears plugged, or somesuch.

Lets' face it; there are hazards no matter how a person travels. Commercial aviation is the safest mode. Not perfect; but pretty close.

Now if you want something that is truly worthless and actually not so funny let us consider the Life Vest. Anyone who has ever used an SMB knows about the manual inflation tubes. Those used on the vests are the same. Good luck putting one in your mouth and inflating by simply blowing.

Then, there is actual survivablility. Assuming it is a successful water landing just how long can a person expect to live in N Pacific water? Not long. Every time we fly my wife and I look at each other and comment that at least they'll be able to find the body.

Fortunately, the airlines are so reliable for planning purposes this whole thing is a non-issue.

Finally got a minute to watch this. Very enlightening, thanks for posting.

This hypoxia talk and video reminds me of this doomed flight: http://en.wikipedia.org/wiki/Helios_Airways_Flight_522
Another doomed flight that I've heard of due to pressure problems: http://en.wikipedia.org/wiki/Turkish_Ai ... Flight_981

Have a nice day!

Wow. Very scary.

Yep, no telling what is going to happen when the crew makes mistakes. Assuming what is presented in Wikipedia is accurate I'd say they died of crew error. Something like in a homicide blunt force trauma being the instrument of death but the cause being the guy who swung the hammer.

This whole post reinforces, to me at least, in addition to precautions for the rebreather diver, for every divier, the wisdom of analyzing every cyclinder of breathing gas a diver uses. Grant you mistakes are rare and the risk is low, witness the very low accident/incident numbers, but it doesn't take long and the consequences of wrong breathing gas are grave.
