Long distance passengers usually choose to fly, because the speed of the plane is so fast that they don't spend all their time on the road. Although the safest means of transportation in the world, it's ok if there is no accident. Once the accident happens, many people will wonder and wonder why the plane doesn't prepare a parachute for every passenger. In fact, the reason is very simple. The parachute jumping of civil aviation aircraft is not dead or disabled, and the chance of survival is very low!
Most civil aviation aircraft use turbo engine, the engine is in the middle and rear of the aircraft, and the aircraft exit is in the position of the aircraft head and tail. When the aircraft is in flight, passengers parachute from the aircraft exit, people are easy to hit the wings in front of and behind the aircraft, or even be inhaled into the engine, causing more serious accidents.
Secondly, the flight altitude of civil aviation aircraft is 30000 feet (10000 meters), while the safe altitude of parachute jumping is 5000 meters. Parachute jumping at 10000 meters requires very professional cold protection equipment. If there are civil aviation passengers parachuting from 10000 meters, they will be frozen as ice hockey as soon as they get out of the plane, because the temperature at 10000 meters is - 30 & deg; C.
Moreover, parachute jumping is a high-risk professional extreme sport, which is not as simple as we think. In film and television works, it seems that parachutists can only open parachutes, but in fact, parachute jumping requires a lot of professional knowledge and superb technology to land safely. Most people have no chance of success in a parachute jump.
Finally, preparing parachutes on airplanes is more likely to trigger riots. Imagine, in the extreme dangerous situation, in order to escape, it is more likely to cause riots, leading to more serious results. These are the reasons why parachutes are not prepared for passengers on the plane.
