Human control can't do it. Why did China Eastern Airlines flight MU5735 fall vertically 20 meters underground, about 7 stories high? Shocking, you can imagine how big the impact is. This can also explain why the plane fell vertically. At that time, it was estimated that all the crew, including the crew, were in a coma, so the plane was out of control and completely in a state of free fall.

There are several possibilities for plane accidents, 1, weather, terrorist attacks, mechanical failure. First of all, the influence of weather has been ruled out. If there is geomagnetic influence, it should have been discovered long ago, so it is difficult to establish this direction. Second, terrorist attacks. There are two kinds of terrorist attacks, one is outside the cockpit and the other is inside the cockpit.

If it is outside the cockpit, including damage to the body, you can refer to the Lockerbie air crash and hijacking accident. Starting from 9 1 1, TWA also has higher requirements for cabin safety. Even if there is a corresponding threat, the driver has enough time to send out a distress signal. If it comes from inside the cabin, you can refer to the air crash of Egypt Air and the air crash of Malaysia Airlines mh370.

In order to prevent similar things from happening, the composition of the flight crew is random. As long as they meet the specifications and have corresponding qualifications, they may become pilots on duty. There are three crew members on this plane. They may or may not be familiar with each other. To be sure, even if one person has ulterior motives, it is impossible to get the other two to reach an agreement in a short time, or to subdue the other two without making a sound. ? Moreover, even if the pilot can completely control the situation of the aircraft, it is difficult to achieve nearly 90 degrees vertical downward. Planes are designed to fly flat, not fall. So we must rule it out.

Finally, there is a mechanical failure. First of all, we must eliminate the engine failure, because an aircraft like 737 can fly for three hours with a single engine. Even if two engines fail, it is no problem to glide like a glider for dozens of kilometers at an altitude of 8000 meters. Will not land vertically. That is a serious mechanical failure, such as the sudden change of the horizontal tail angle responsible for the pitching angle of the aircraft, which causes the aircraft to bump violently, and the instantaneous impact force makes the pilot unconscious and unable to control the aircraft, leading to serious consequences.

My judgment is that the nose of the plane is controlled by the horizontal tail. The horizontal tail is controlled by computer through manual operation or automatic cruise mode, and the specific action is carried out by hydraulic equipment according to instructions. When the plane encounters complex airflow in flight, it uses the flat tail to keep the flight stable, but when the flat tail controls the nose downward, it fails! At this time, the hydraulic equipment is stuck, even manual intervention will not help, and the plane will soon form a downward vertical landing and cause tragedy.
