The China Eastern Airlines passenger plane dropped 8,000 meters quickly within 3 minutes before the crash. What concept? , what is this concept? At an altitude of tens of thousands of meters, after the plane made of aviation materials crashed, only the wreckage was left, what's more, people with bodies certainly have no possibility of survival, and I'm afraid even the bodies are hard to find. Even if the body is found, it is difficult to tell who it is, and it can only be identified by scientific means. It's really a saying that "the body will not be seen after death". At this time, the most painful and sad thing is family. May the dead rest in peace and the living grieve! Willing to stay away from us. Expectation is always expectation and always gives people spiritual comfort, but in the end we still have to face the reality. To tell the truth, falling vertically, so fast, only the fragments of the plane, the purses of the people on board, and the traces of burning can be seen so far. The seriousness of the consequences of the explosion of more than 20 tons of fuel can be imagined. It's just that no trace of personnel has been found yet. As a matter of fact, for us, the public would rather hear about people who have not yet been acquired than hear about the death or disappearance of people.

Nowadays, from the country to the local, from the official to the individual, people are involved in personnel search and accident rescue. There's really nothing we can do now. Pray for them, pray that the only miracle can happen. What happened at that time, from the current point of view, we can only find the black box (flight data recorder) as soon as possible, and after processing and analysis by experts and technicians, we can give the public a final answer and make better countermeasures for future flights. There is a word in the field of security called intrinsic safety. Intrinsic safety is the highest realm that human beings have been pursuing, but it is not static, and it is constantly improved with the progress of science and technology. Intrinsic safety design is aimed at misoperation, which can be automatically eliminated when faults occur to ensure personal safety. I hope our science and technology are more and more developed, and our citizens pay more and more attention to safety. Let's start with wearing a seat belt!
