What is the cause of the crash of China Eastern Airlines MU5735? What happened before the crash?

1. As for the first case, when China Eastern Airlines just had an accident, all kinds of people came out and shouted, all of which were losses. Comprehensive news, the domestic crash has ruled out the possibility of shooting down.

2. Hit a bird. The passenger plane began to descend at an altitude of about 9000 meters. At this altitude, there are very few birds that can fly, and the probability is very, very low. If you hit a bird, there are two situations. First, it hits the wing and the engine side. If this is the case, the driver had enough time to point out the problem, make a report and ask for help, but he didn't report it. Second, the bird directly crashed into the cockpit, causing two pilots to be injured, making them unconscious or unable to control the plane, thus the plane was out of control, but the probability of making two pilots unconscious at the same time was very, very small.

3. The probability of human factors is very small. First of all, the captain is the second generation, and his business ability is low-key and solid, while the co-pilot is a five-star captain with 40 years of flying experience. Many of his apprentices are powerful people in the industry, so there should be no problem in manpower control.

The plane is probably out of order. First of all, Boeing 737 has not broken down twice. The latest one was the crash of a 737MAX 8 plane from Jakarta to Bangka Penang in lion air, Indonesia on 20 18. When analyzing the cause of the crash, investigators said that mcas (a special mobile enhancement system to prevent stall) was out of order, and the system repeatedly pushed the nose down.

5. The weather. Judging from the satellite cloud picture, the weather conditions at that time were not bad, so the possibility of extreme weather was relatively small. But it is also possible that the weather is unpredictable and thunderstorms suddenly appear. It is not impossible for lightning to hit the plane and cause various instruments to fail.

So to sum up, the possibility of aircraft failure is relatively high, and extreme weather is also possible. Of course, it may also be the superposition of multiple factors, leading to tragedy. In the end, it is necessary to find the black box as soon as possible in order to investigate the final reason.

The black box has just been found. The cause of the crash and what happened on the plane at that time will not be known until the black box is decrypted. Maybe it's the mechanical failure of the plane, or maybe it's the weather. Only by decrypting the black box can we know what happened on the plane. Now the recorded black box is being decrypted, and I believe the cause of the plane crash will be announced soon.
