Slogans about the quality of airplanes

1. Plane crashes usually happen in an instant. Even if every passenger has a parachute, it's too late to finish the preparation for parachuting. \r\n2. Skydiving is a very professional technology, which cannot be mastered and accepted instantly by ordinary passengers without special training. \r\n3. At present, in the design of aircraft, there are generally only two front and rear doors. In case of emergency, it will cause great confusion because passengers are scrambling to jump first, which will affect the pilot's operation and may lead to a bigger accident. \r\n4. Airplanes are designed to be light and not heavy. Imagine that a 2-seat plane needs to be equipped with more than 2 parachute bags. How much load will it add to the plane? Also, where is the parachute bag stored when it is not in use? Under the passenger's seat? No, there is no room there; Overhead? No, the passenger's suitcase is already small, so there is no place to put the parachute bag. \ r \ nOn second thought, the plane designer gave up the design scheme of personal parachute bag on the plane.
