"Compared with ordinary traffic accidents on the ground, aviation accidents are often unpredictable and sudden disasters." A civil aviation staff member who asked not to be named told reporters that besides the well-known heavy casualties and huge economic losses, aviation also involves the planning, organization, command, coordination and control of flight, ground support, air service and other aspects. The work site is scattered and greatly influenced by the natural and social environment, so it is difficult to find the cause of the accident immediately.

At the same time, the rescue of aviation accidents is also extremely difficult. "Because the accident may occur in desert grasslands, mountains, or rough seas, or even densely populated modern cities, it brings a lot of inconvenience to the rescue, and it is difficult for external rescue forces to rush to the scene to participate in the rescue at the first time."

In addition, "a plane crash may cause the fuselage to break, and passengers may be buried in the wreckage of the plane or thrown into the grass and Woods. Therefore, after the rescue forces arrive at the scene, they should use life detectors or other advanced search and rescue equipment to conduct comprehensive search and rescue in time to win valuable rescue time. "

Zhang Lei said that "search" and "rescue" are often put forward together as words, but in fact they are different tasks according to different rescue scenarios. "Search usually refers to the use of existing personnel and facilities to determine the approximate scope of people in distress according to the distress information, and to take certain search techniques and methods to find people in distress according to the actual situation such as topography and meteorology.

Rescue refers to finding people in distress, providing them with initial medical assistance, basic life support and other needs, and transferring them to a safe place for medical treatment. In general,' search' is a difficult point, sometimes it's like looking for a needle in a haystack, but you have to race against time; Only when you find it can you have the next' rescue'. "

Armed police officers and soldiers rushed to the crash site to carry out rescue.
