Description:

This shows a passenger can be ejected by explosive decompression, that is why the B-29 had a cage to keep crew from being shot out is explosive decompression occurs. It is pretty much a myth that a small handgun can cause explosive decompression. Under normal conditions most commercial and military aircraft have enough margin of error (extra strength), that in most cases a small caliber gun is just going to make a small hole and make no noticeable cabin pressure lose. The occupant is not sucked out. The higher relative pressure inside the cabin pushes the passenger out. Suck is not a real technical term in physics. You can't really pull on air; you can push on air and do push it. If you keep your seatbelts fastened, then even if there were to be an explosive decompression, you would still remain inside. Most passenger aircraft the windows are too small to have an adult to be easily be blown out. Depressurization lift you up? Not normally. Gravity is still a factor. Assuming the plane is upright and pulling 1 positive G in a normal attitude. If you were in a stairwell and an overhead window blew out, then it is possible you could be blown directly upward. But I can't think off hand of any aircraft that is configure in a way that is likely. The closest I can think of is a case like is a cabin failure like. . Flight 243 http://en.wikipedia.org/wiki/Aloha_Flight_243 http://en.wikipedia.org/wiki/Image:Alohaairlinesdisaster.jpg I doubt the depressurization blast itself would normally be powerful enough to lift you up enough to blow you out. But the resulting slipstream is more likely to blow you out if there is extensive damage. The combination of the two forces increase the odds of ejection. Typically the crew in the cockpit are at higher risk then the passengers. Typically the windows are bigger in the cockpit and there is much higher risk of damage like from bird strikes. If a window is blown out in a cockpit or in a tail gunner position, it is possible to be shot out like a BB in a gun. Flight 5390 Pilot windscreen failures http://en.wikipedia.org/wiki/British_Airways_Flight_5390 Normal you will not be directly lifted up by depressurization because in most cases you don't have a large reservoir of air under you to blow you out like a gun. However if there is structural failure in such a way the slipstream comes through the cabin, it is very easy to get blown out. Good depressurization description. http://en.wikipedia.org/wiki/Cabin_pressurization In the unlikely case of cabin decompression hypoxia is more likely to be fatal. If you fly on a pressurized aircraft you should pay attention to safety lecture. Depending on your health and the altitude you can pass out in seconds or minutes. Hypoxia death is not normally a direct threat in decompression, but if the pilot doesn't get his O2 on before he passes out it could be fatal for everyone on board. Like in the case of the golfer.

Seeing this reminds me of when I had a boom operator ask me to come and look at something mid-flight. One of the scanning windows in the back of the KC-135 was somewhat shattered, not just a crack. Coudn't tell how many layers it went through and I sure as hell wasn't getting up close to see. I was like AHHHH!. I think it's time to go to a lower altitude and strap in!

But Payne Stewart did not fly out of the window. Was his body floating in the plane?

milton456 Stewarts plane never presurized and all died from lack of oxygen. No floating

Whether or not there is pressurization, there still is gravity. If I remember correctly the fighter pilots that flew around Payne Stewart's aircraft trying to hail the aircraft, said as near as they could tell all the windows and doors and fuselage was intact. Yet there was condensation or frost on the windows which sometimes is an indication of rapid decompression.

when are they gonna take some mammalian life up into space and eject them out the airlock so we can see what REALLY HAPPENS in SPACE. You could have remote EKG sensors strapped to the animal to monitor its heart attack to!

That's sick. Besides we already know. There are astronauts who have accidently breathed vacuum you know.

It's unclear to me if his aircraft suffered rapid decompression or if it never pressurized. I haven't seen any detailed evidence, and I'm not sure enough survived to make a proper determination.

In the "highly unlikely event" of cabin depressurization an oxygen mask will drop down in front of you just shortly after you're sucked out. Be sure to secure your own mask before helping others.

wouldnt explosive decompression send any un-fastened passengers straight up into the top of the fuselage?

i was just thinking of the comet accidents in the fifties...maybe its because the fuselage ripped on the roof of the aircraft...great videos though

In the case of the comet scenarios, it is reasonably possible they were shot up but it is more likely they could have been blown out by the slipstream.

During depressersation hypoxia is more likely to kill you then the risk of being blown out. In a typical aircraft the cockpit is the most risky place to be as the windows are typically bigger and more likely to get hit with things like bird strikes.
