Cause of mu5735 accident of eastern airlines

The cause of China Eastern Airlines mu5735 accident was out of control.

Now everyone only knows that the first task of the laboratory in Washington, USA every day is to download the initial data of the black box for free. Although the black box was sent to the United States, the data was downloaded for free, and the decision to repair the data was made according to the level of data storage damage. This also leads to a great difference in the time to repair the black box data. Some black boxes can repair all the data in 12 months, some take 36 months to repair most of the data, and some may only repair a little data in 13. So wait patiently.
