The consequence of jumping out of a plane without a parachute can be death.
But if you don’t have a parachute and you have to jump out of an airplane, and the airplane is thousands of meters above the ground, what are the chances of surviving a free fall?
First, we hope it never happens.
If there’s a parachute, there might be a chance.
But if you don’t have a parachute and jumping out of the plane is the only option, the first thing you should do is look for water on the ground, like the sea or a river, and then try to take aim.
Assuming everything is done perfectly, what are the odds of survival?
Before jumping, find a large object to cushion the impending free fall, preferably wrapped in a ball.
The buffer absorbs some of the kinetic energy of the fall, making survival possible.
For example, Yugoslav flight attendant Vesna Vulovi?
Miraculously, she survived a DC-9 explosion that forced her to jump about 10,160 meters from the plane and earned her a place in the Guinness Book of World Records.
She was at the rear of the plane, wedged between the dining car and another crew member.
Due to the distance from the center of the explosion, she and her chair were blown out of the plane.
Miraculously, she survived because of the deep snow at the landing site and cushioned by her seat.
Falling freely from an aircraft at normal cruising altitude, the individual will eventually reach a constant speed, which is called terminal velocity.
At this point, the individual’s gravity is equal to the air resistance, and the speed no longer increases.
A normal parachutist jumping from a commercial aircraft flying at an altitude of about 10,000 meters would have a terminal speed of about 54 to 58 meters per second.
If a person fell into the sea at that speed, it would be like hitting concrete.
Although water is not as hard as cement floor, it has surface tension, which is why water has a tendency to clasp together.
At the same time, this means that water exerts a force on objects lying on its surface.
Since we’re talking about a person (a considerable amount of mass) falling from thousands of meters, the impact force at the moment of contact with the water would be enormous.
This force is influenced by two factors: the mass of the object and the area of contact between the object and the water.
The mass is fixed, but the contact area can be changed.
Assume a position that minimizes the contact area for a large impact force.
For example, a foot-first touch position, or a head-first position like a diver.
Of course, this position will increase impact speed slightly, because the streamlined body will reduce air resistance.
Once it breaks through the water, its speed drops dramatically.
In fact, super fast changes in speed can produce forces beyond the human body’s range.
It’s possible for humans to withstand a 100G deceleration for a short period of time.
For example, in 2003, race car driver Kenny Br?
One of the biggest accidents in motorsport occurred when the measured deceleration speed was 214G.
But he survived.
From the point of view of the plane falling, at least around 300G, normal human is not able to withstand.
With such a large impact force, it would cause massive bleeding inside the body, damaging vital organs and causing fatal injuries.
In short, if you jump out of a plane without a parachute, your chances of survival are slim.
However, when there is no other choice, find a buffer, choose a river, lake or sea where there is water or thick snow, and fall in a good position, you may still have a chance of survival.
