What Happens If You Get Sucked Out of a Plane?

astroengine writes "We've all wondered about it. When flying at 30,000ft, you look around the cramped economy class cabin thinking 'I wonder if I'd survive being sucked out of this plane if a hole, say, just opened above my head?' That's probably around the time that you should fasten your seat belt. According to medical experts interviewed by Discovery News in the wake of the Southwest Airlines gaping hole incident, the rapid depressurization, low oxygen levels and freezing cold would render you unconscious very quickly. Assuming you don't get chopped in half as you exit through the hole and hit the tail, you'd be long dead before you hit the ground. Nice."

      The Windscreens are still there in part because GA and military flights may not be tracked by Civil ATC, and may not be equipped with TCAS or equivalent, leaving manual sighting as the only way to avoid them. Without ILS IIIc, the windscreen is also still essential to landing procedures.

      I assume you're referring to the MIT experiment, and I have to fight the urge to insult your intelligence. The MIT team used statically positioned mirrors, spent hours trying to focus them on a static target, waited around for clouds to go away, and then eventually got ignition. This doesn't even come close to matching the myth, since a static rig made of modern mirrors carefully aimed at a static target is completely different than hundreds of soldiers shining bronze mirrors on a ship that's bobbing around in the water. If they set out to show that it's possible to use mirrors to start a fire, they succeeded - if their intent was to show that the Archimedes story is true, they failed. They are rightly non-committal in their FAQ since it's clear that the experiment wasn't designed to replicate the actual conditions.

      Yes, everyone knows that sunlight can be focused in order to heat up or ignite objects - no, it's not practical to use hand-held mirrors to light an attacking enemy ship on fire. The MIT experiment further confirms the result which the Mythbusters achieved - they showed that it's impractical even under relatively ideal circumstances, let alone under battlefield conditions. The Mythbusters did what they set out to do - they showed that the myth was false. After much criticism they went back, tried the test with some modifications, and again showed that it was false. Clinging to the MIT test as "evidence" that the Archimedes myth might possibly be true is ludicrous.

      Research is not about making one single experiment and when it fails concluding "it can't work". Research is about making LOTS of SIMILAR experiments ... If you continuously fail, you try to figure WHY you fail first.

      Whenever possible, ideally, sure. It's certainly not an absolute requirement, though, and the number of trials will always be dictated by your budget / time constraints. The Mythbusters generally DO perform multiple trials, they use variations in their experiments to try and simulate different conditions, and they go back and retest some myths when there's cause to do so. On more than one occasion they've retested a myth which they previously "busted", and got positive results on the second run, so they're certainly not hesitant to challenge their previous conclusions and to admit their mistakes when they're identified.

      It was something like roughly 80 meters high, iron and bronce cladded to prevent it getting ignited, it hat windows to shoot out with catapults or bows, about 100 soldiers where needed to move it; it had wheels all under its floor and used a mechanism with ropes and big things like the anchor lifting things on sailing ships to move it. Those "wheels" for the rope mechanism likely needed over 50 people to operate.
      On top it had a bridge to be lowered on top of the walls. They sieged a greek city with it I believe. However they failed as the tower finally got destroyed, I think I remember an earthquake was involved.

      But as soon as you got to low altitudes, opening up your arms a la skydivers would very rapidly take you back to terminal velocity for that position, which can range from 38 to 54 km/sec. I like HELP (the posture) until you get down to ten thousand feet or so, facing flat down splayed and with your jackets and clothing as spread out as possible to try to get your speed down to the better side of 40 m/sec and for the rest of the way down looking for a place that might cushion the impact, and steering for it to the extent you can manage. A fair number of people have survived free falls from airplanes high enough that it doesn't matter, terminal velocity was easily reached, a very few of them so lightly injured that they can even "walk away", although more commonly they barely survive and that only if medical help is immediately at hand.

      Surviving here is like winning a game of egg-toss where you are the egg. You need to spread your de-acceleration out over the longest distance possible in impact. The equation involved (assuming uniform acceleration) is v^2 = 2 a H where H is the stopping distance and a is the acceleration experienced while stopping. Humans have survived a \approx 100 g, or a stopping distance of roughly one meter for an initial velocity of 45 m/sec (100 mph). They do better, of course, if the stopping distance is 2-3 meters, or if one is travelling more slowly -- the square means that a comes down rapidly with v so that stopping from 38 km/sec (roughly 80 mph, terminal velocity if you have e.g. a large overcoat and "parachute" it to slow your rate of fall) over 2 meters is only 37 g's of acceleration. a > 50 g makes it pretty unlikely to survive.

      So what are good targets? Hay rolls out in fields -- good for a bullseye although you need a pretty big one in a soft, plowed field to be carried away with a ruptured spleen and subdural hematoma but alive. Tightly packed pine forest -- acually better, if you avoid skewering directly onto a tree and your head and kidneys take the punching from the branches as they break, because you might slow down over 5 to 10 meters, where the latter reduces a to 20g, easily survivable and you could even walk away from it . Big bushes of any sort better than hard ground, the bigger (taller) and denser the better. Spongy loam better than concrete (maybe a peat bog?). Deep water better than normal ground, but...

      Water carries its own risks. It is an incompressible fluid and quite dense and you can't breathe it when unconscious, so hitting it in, say, a belly-flopper will just cause you to pop. Hitting water that is foamy on top (so that the water contains a lot of air bubbles that can act as a shock absorber) is better than hitting still water. Hitting water that has any sort of "splash" underway on the surface is good, as it might let you get a foot into the water on your way down and start to push the water sideways out of the way in some sort of turbulent flow instead of having to just push it all aside in front of you. The usual prescription for survival here is to fall splayed until quite close, then go straight up vertical, feet first, toes pointed (streamline), arms over head, and clench that sphincter for the 100 mph enema! You'll probably break your legs on the impact, but the rest of the shock will be transmitted up your spine, which is actually quite strong, and if your head is at the right angle your spine may not be jammed up into your brain or your head may not whip down so hard that it snaps your neck. In that case, if you aren't knocked out and don't mind dog paddling with possibly splintered leg bones and broken ankles, hey, you might survive long enough for a nearby boat to get you out.

      So what are the odds? Miniscule, of course. Teensy. Small indeed. Perhaps not much better than if you do nothing at all and let luck determine if you hit that perfect pine forest or the trash pile at the foam rubber factory. But hey, it's something to do on the way down besides just going "Oooooh shiiiiiiiiiiiiiiiiiiiitttttt....." and watching the ground reach up to swat you into oblivion.

In the hawaii incident, there was a gigantic hole, the flight attendant was not sucked out movie style but (probably) swept up by the massive wind force that occurs partly simply because aircraft move so fucking fast. Nobody knows how she met her dead. It might be comforting to think she died instantly and without pain... if that helps you sleep at night.

    Another incident involved a pilot being SUCKED out through the window in front of him (showing just how wrong the DISCOVERY mythbuster program is in its logic and research). He was SUCKED out and exposed to the cold and lack of oxygen for a long time AND survived.

    Another incident involves an aircraft breaking up in mid air, all died but the family got record damages because experts had shown that they most likely survived the break up and were alive and aware the entire way down. Families were from one of the south american countries, maybe chili if you want to google it (to lazy myself).

    The simple fact is that Myth Busters is a great example of bad science where they ignore recorded evidence and then twist the experiment until it doesn't resemble to claim at all. The clearest example was the "myth" of Jaws being able to hit a boat. So they tested the myth of a super sized shark hitting a boat, by using a smaller shark because Jaws was an unrealistic size... well? That is the myth, the myth is NOT real shark doing something real shark don't do.

    Same with the being sucked out. There is more then one way, and pressure difference isn't the only one. Air rushing past a hole tends to create a sucking force itself (see how your engine sucks fuel up into the air) and a massive hole would create all kind of secondary forces. According to mythbusters, large buildings don't cause winds to rise to such level that they blow people of their feet because the pressure difference ain't big enough. Well, shucks.

    So basically, discovery claims things contradicted by their own programs. Guess that answers who takes discovery serious, ABSOLUTELY NOBODY.

    Remember, it's not the fraction of oxygen that decreases with increasing altitude -- that stays the same at 20%. It's the partial pressure of oxygen (PPO2) that decreases linearly with the ambient pressure. IIRC, we humans require a PPO2 of 0.12 bar to remain conscious, which is what you have at something like 12,000 feet (see this conversion table).

No, you don't, as this depth is too shallow to enable dangerous amounts of nitrogen to dissolve in your blood, at least in time spans you can reasonably stay there without getting trouble with hypothermia and exhaustion. Regular dive tables don't even extend to depths shallower than 10 meters, at which you can stay for more than three hours. I'm not certified to make dives that require decompression, that's pro/military territory, but I believe that 3-7 meters are actually common depths for making your last decompression stop.

      On a side note: the bends are a real concern when traveling in aircraft; for instance it's highly discouraged to fly less than 24 hours even after a recreational dive that doesn't require decompression. The pressure in the cabin of a normal jet liner is maintained at a level which corresponds to about 2-3 kilometers above sea level. I'd guess that at least some people would have problems with a sudden decompression at up to 12000 meters, as susceptibility to getting the bends varies greatly from person to person. However, I doubt that it would be severe enough to kill you outright before you reach a lower altitude if you were unlucky enough to be sucked out of the plane.

Given that he was barely conscious to begin with, the excessive G-load caused him to black out once again. Soon after, the pilot wakes up and lands the plane at the nearest airport. They pull up to the FBO and, without looking back at the aircraft, request a car and drive to the nearest bar. The NTSB recorded that nearly half the horizontal stabilizer was torn off and the wings had nearly 10 degrees more upwards bend than they should. Anyway, the rapid decompression really didn't have any affect on the guys, and I would guess a King Air at cruise power can fall as quickly (if not faster) than a human, and obviously they were not dead. There was an incident a while ago about a Lear Jet that had a window blow out and for some reason the pilots weren't able to get their masks on in time...the auto-pilot kept the plane at about 35,000 feet like it was told and those guys never stood a chance...it just kept flying out into the Pacific until it ran out of fuel.
