10 km without a parachute: what to do if you fell out of an airplane
6:59:00 Altitude 10, 000 meters
Your flight can be called late night, or you want - early morning. After takeoff, you were lined up to sleep, and suddenly wake up from a scorching ice wind. And that sound is a heartbreaking, deafening roar. "Where I am? - you think. “And where did the plane go?”
You are at ten kilometers above the ground. All alone. And you fall.
The situation is bad. But now it would be better to focus on the positive aspects (apart from the main thing - that you at least somehow managed to survive your plane). Earth gravity is now a fierce enemy for you, but you have another ally - time. Believe it or not, your current situation is much better than if you had fallen off the fifth floor balcony. More precisely, your position will become better. In the meantime, problems with oxygen at this altitude will lead to hypoxia and loss of consciousness, and for a couple of kilometers you will fall like a brick. Then consciousness will return, and then try to recall this article. However, in any case, you will not miss the final stop, that is, the ground.
It makes no sense to argue that the chances of survival when falling from a ten-kilometer height are not so many, but at the moment you still have nothing to do and no one bothers to think about your own situation. There are two ways to fall from an airplane. The first of these is free fall without any attempt to slow down its flight. The second is to play the role of the "rider on the wreckage." This term was put into circulation by Jim Hamilton, a Massachusetts amateur historian who created the page of "freefall researchers." This is an extensive database, which includes almost all cases of falling from a great height. "Rider" in his terminology is the one who managed to grab hold of some fragment. So, in 1972, the Serbian stewardess Vesna Vulovic served a DC-9 flight. A plane exploded over Czechoslovakia. The flight attendant flew 10 km, being sandwiched between her seat, a buffet trolley and the body of another crew member. She landed on a snow-covered hillside and slid for a long time to a halt. As a result, she received serious injuries, but remained alive.
If you are surrounded by something like a cocoon of debris, the probability of surviving when you hit the ground will be significantly higher. This is Hamilton's opinion based on convincing statistics. Since the 1940s, 31 such cases have been recorded. Those who survived after solitary free flight are much fewer - only 13 cases registered or credible. A superstar in this club of fantastic lucky ones can be considered a military pilot from New Jersey Alan Maggie. In 1943, when he was carrying out a combat mission in the sky of France, he was thrown out of a B-17 aircraft. Flying 6 km, he broke through the roof of the railway station. Almost immediately, the Germans captured him, who were shocked to see him alive.
For now, let's forget about whether you fall freely or were able to cling to some fragment of the fuselage. The first thing you should be interested in is the "final speed" (it is also the "steady-state fall rate"). The force of gravity pulls you down and seeks to disperse you. On the other hand, like any other moving object, you encounter "frontal resistance", which increases with increasing your speed. At some point, these forces are balanced, and the acceleration ceases, that is, you go to the "steady speed".
Depending on your weight, size and density of the surrounding air, you must accelerate to no more than 200 km / h, and this will happen only for about five hundred meters of free flight. That is, falling from a skyscraper or from a ten-kilometer height, you will hit the ground with the same force. But from the roof of a skyscraper to the sidewalk you fly in 12 seconds, and falling from the “airplane” height, you will have time to read this entire article.

By this moment, you have already descended into those layers of the atmosphere where you can breathe more or less freely. Consciousness returns to you. Two minutes remain before hitting the ground. Your next task is to decide whether you want to live on. If so, then keep in mind that, as paratroopers joke, "they die not from a fall, but from a landing."
Without losing your presence of mind, try to aim.
