A helicopter crashed into the sea in Xiamen, killing three people. Do you know what will happen before the plane crashes?

On March 19, the Civil Aviation Administration of China announced that a helicopter in Xiamen crashed into the sea while performing an air rehearsal mission, killing three people on board. At present, the Civil Aviation Administration of China has started the second-level emergency response, and will immediately set up an investigation team to investigate the matter in Xiamen.

On the afternoon of March 19, the command duty room of the Ministry of Transport immediately dispatched a rescue flying team to assist the helicopter. After discovering the wrecked helicopter, they immediately took diving action to carry out rescue. Finally, rescuers found three bodies in the crashed plane, but one person was still missing, and the rescue continued.

Once the plane crashes, the mortality rate is almost 100%, so how can we know the plane crashes and what are the signs between planes? And get ready at the first time?

There are omens before the plane crash, for example, the fuselage of the plane suddenly begins to bump, the plane begins to slide at high speed, and there will be unknown smoke in the cabin of the plane. A lot of black smoke will come out from the window outside the cabin, and then the aircraft engine will stop urgently, which will generally disappear with the huge roar of the aircraft flight. These conditions are usually a harbinger of a plane crash.

In case of plane crash, don't panic, do everything for yourself, prepare for possible protection and strive for rescue. Even if the death rate of the plane crash is almost as high as 100%, the possibility of survival is very low, but when you find these omens, don't panic, save yourself urgently, there is still a certain chance of survival, and strive for one in ten thousand chances of survival for yourself.

When the plane is unstable and about to fall, it is necessary to fasten the seat belt to resist partial impact and reduce the harm to human body. Moreover, don't leave your seat to find your relatives after the plane crash. Many people are mixed, which will delay the escape time and may cause a stampede accident, which will have a great impact on the already unstable aircraft and shorten the escape time. One and a half minutes after the plane crash is the golden escape time. We must do our best to take protective measures and strive for the possibility of survival for ourselves.

Passengers on the plane have oxygen masks above each seat. When the air pressure in the plane reaches a certain level, the oxygen mask will automatically fall off. The sooner the better.

If the plane is forced to land in the water, there is a life jacket under each passenger's seat, so it should be put on in time, and the lifeboat and escape slide on the plane must be used correctly, so it is still possible to survive.
