The accident investigation of flight MU5735 faces three major challenges. What are the doubts about this accident?

Netizens who have paid attention to the crash of China Eastern Airlines mu5735 on March 2 1 should all know about this trial airliner. The second black box was found on March 27, but this does not mean that the cause of the passenger plane crash will be concluded soon. In this accident, there are actually many doubts, such as why the plane crashed without warning and why the air traffic control department did not receive any information about the abnormality of the plane.

On the afternoon of March 2 1, the last flight trajectory of China Eastern Airlines flight M 155735 was recorded by the local surveillance camera, and the angle was found to be steep and rapid. Judging from the phenomenon of this accident, the first impression is that it is not normal and it feels particularly strange. There may be two reasons for the plane's basic vertical descent in a short period of time. One is that the plane suddenly got out of control. In this case, even if the pilot wants to control, there is nothing he can do to change the attitude of the plane, which is possible. Another possibility is that the aircraft may be damaged by external forces in the air, that is to say, the aircraft will disintegrate in the air, so if there is a big structural damage, there will be a rapid decline.

Since the two black boxes of mu5735 have been found, the cause of the accident has also attracted much attention. There are three major challenges in this accident investigation. First, why did the plane drop without warning? The air traffic control department didn't receive any abnormal information about the plane. Second, the plane crashed violently and the wreckage was very trivial, which made it very difficult to understand the cause of the accident. Third, the geographical environment of the site is very bad.

Even so, civil aviation experts will do their best to investigate. At present, the related decoding work is already in progress. Through various efforts, I believe that significant progress will be made and an account will be given to the national society and the families of the victims.
