A story of plane crashes In the late 1980s, Pan Am Airways in the United States had an air crash that shocked the world. No passengers and all crew members survived.
The cause of the accident was that 38 minutes after the plane took off, a bomb placed on the plane by terrorists directly blew an 11 cm hole in the plane, which eventually caused the plane to disintegrate. Pan Am later paid tribute to the victims. The families of the victims were each compensated US$10 million.
Then some people will ask, why do airlines prefer to compensate huge sums of money rather than provide each passenger with a parachute?
When forensic doctors conducted autopsies on the remains of the victims of the air crash, they found no traces of accidental injuries from the explosion. Most of the people suffered from body failure due to the extremely low temperature in the sky. Die due to warmth.
So some people thought at that time: If everyone had a pack of parachutes when the plane crashed, such a tragedy might not happen!
In fact, this is not the case. The reason why airlines do not equip every passenger with a parachute is because the flight process of an airplane includes three stages: takeoff and climb, smooth flight, and descent and landing. In these three stages, different things may happen. accident.
We all know that professional skydivers only start preparing to skydive when the aircraft is hovering stably. No athlete has ever skydived while the aircraft is climbing and landing, because this situation will cause the skydiver’s center of gravity to become unstable and Danger occurs.
Therefore, if an accident occurs during takeoff and emergency landing of the aircraft, even using a parachute will not help, and due to the inertia of the aircraft, you may be sucked into the engine the moment you open the parachute bag.
In other words, when an accident occurs during takeoff or landing, we can only trust the crew’s flying ability and cannot blindly parachute.
So if an accident occurs while the plane is flying smoothly, can skydiving increase our chances of survival?
When the aircraft is in the relatively stable stratosphere, if an accident occurs, it will actually be difficult for us to complete the skydiving mission.
We all know that when an airplane is flying smoothly, the altitude will reach between 6,000 meters and 12,600 meters. At this altitude, the outside environment can be described as extremely harsh. The low temperature, low pressure, and low oxygen environment will make you in plain clothes feel uncomfortable the moment you go out. We fainted from the cold, and only woke up when we were almost in free fall and approaching the ground. Of course, opening the parachute at this time would not help.
Professional skydivers will wear professional protective suits before skydiving to protect themselves from the influence of the external environment. However, no one will fly wearing professional skydiving equipment. If they do, they will be detained by the police for questioning.
In addition, even if some people say that they are physically strong. And can withstand such cold weather, can they still skydive?
In fact, it is not the case. At an altitude of 10,000 meters, if you are not accompanied by a professional skydiver. You can easily lose your way in the air and fail to reach the designated position. Even if you land safely, you may fall into the ocean. Or encounter new things in the deep mountains and old forests. Danger. From this point of view, when an airplane accident occurs, parachuting to save one’s life is indeed a worthwhile approach.
The reason why civil aviation aircraft are not equipp with parachutes is because they are afraid of secondary accidents. Caused by passengers who do not know how to operate them.
So if there is an accident on the plane we are traveling on. Can we just sit back and wait for death?
The first thing we need to make clear is that the crash rate of airplanes is the lowest among all means of transportation. And the accident rate is only one in three million. Saying this can alleviate your unfounded worries.
Because the accident rate of the cars we take for daily travel is as high as 1 in 10,000, so feel free to fly by plane.
In the event of an airplane accident, all we can do is fasten our seat belts and put on the dropped oxygen masks to ensure that our breathing is stable to avoid respiratory arrest.
Secondly, if the captain can handle aircraft accidents well, such as aircraft engine failure, we can rest assured.
However, if the plane has to make an emergency landing as a last resort. We should not panic and follow the flight attendant’s instructions. Before the captain issues a crash command, we must take appropriate anti-collision postures in our seats.
Once the captain realizes that the flight mission cannot continue. He will immediately send an emergency landing request to the tower. And after contacting the nearest airport, the emergency landing mission will be carry out.
If it is a cross-border flight, the emergency landing location may be on the sea. Before the emergency landing is complete. You must put on a life jacket and other life-saving suits. And wait for the arrival of rescue after the emergency landing.
Then some people may be curious. The crew on the plane must have performed parachute training during flight training, so why not equip them with parachutes?
In fact, this is to prevent these people from leaving themselves a way out when a dangerous situation comes. All they can do is to do their best to keep the passengers on the plane safe. And there is no way out!
Seeing this, everyone must have understood the reason why passengers are not equipp with parachutes on airplanes.
I believe that with the development of science and technology in the future, the crash rate of airplanes will become even lower than it is now. It is impossible to say that every passenger will be equipp with a parachute by then
