Accurate data analysis China Eastern Airlines MU5735 was dark for 2 minutes. What did the crew and passengers experience?

Probably a shock, there should be no coma before the crash, which can be seen from the plane's short climb of more than 300 meters and the plane's rapid crash within a few seconds after the climb failed. It can be proved that they were not in a coma before the plane crashed. There are several situations in which coma will occur when the plane crashes:

First, the engine room lost pressure. Loss of cabin pressure means that the pressure difference between the inside and outside of the aircraft is zero. The higher the plane is from the ground, the thinner the air will be, and people will have altitude sickness at the plateau. Because oxygen is too thin and the air lacks oxygen, people will inhale less oxygen when breathing, which will eventually lead to symptoms such as insufficient oxygen supply, accelerated breathing and dizziness. Therefore, it is a problem how to reach the ground after the plane rises to high altitude, so it is necessary to pressurize the engine room.

When the plane starts to take off, the pressurization system of the plane will slowly pressurize the plane. If there is something wrong with the pressurization system, passengers will soon lose consciousness due to hypoxia and suffocate, and will die if they are deprived of oxygen for a long time. If there is not enough oxygen supply, the final result is that all of them die of lack of oxygen.

This time, the flight of China Eastern Airlines appeared in just a few minutes. Even if there is no problem with the pressurization system, the eardrum will be very uncomfortable during the rapid descent. During the take-off of the plane, some airlines will ask the stewardess to chew gum for you, which can balance the pressure inside and outside the cochlea and relieve the discomfort of the ears.

This happens when the plane takes off and descends slowly, what's more, it crashes in a few seconds from the height of 1000 meters, so there may be great discomfort in the ears when something happens.

Second, the acceleration of the plane leads to slow blood circulation and lack of oxygen in the brain. When the plane hit the ground, it dropped from 490 knots, that is, more than 840 kilometers, to the speed equivalent to seven or eight hundred kilometers, which was a high-speed collision. According to the human overload and impact endurance test conducted by Dr. john paul stapp in 1954, the fastest acceleration and stop record in human history was 46.2G, but the test caused damage. At that time, he was not in a coma in the experiment and did not seriously damage his health. He is 89 years old.

The "g" mentioned in it refers to the unit of force when moving at high speed. When it bears a great downward G force, the blood of the body will accumulate in the legs, because the heart can't pump blood to your brain, and the brain will bear a lot of pressure, which may lead to your coma. In addition, the plane itself is still spinning in the process of falling, that is, it is 360 degrees perpendicular to the ground and rotates around its own axis, just like flipping you down from the sky.

When China Eastern Airlines dived this time, the fuselage was intact and there was no disintegration in the air. I checked the information. The passenger plane has a payload of only 3.5G, and the fighter plane is 9G. Let's take a look at G-value training in America.

12G, the pilot who challenged the limit, was unconscious after about 1.5 seconds. Ordinary fighter pilot 9G training, fainted after 2 seconds. This is still professionally trained and wearing protective pants. When the average adult male is below 5.32G, he can obviously see that his body is' pressed' on the seat, and he is almost unconscious, while the aircraft load is below 3.5. Under the action of positive and negative G forces, most people may not faint, but watch the plane crash in panic unless you are shocked.
