How come all planes don have parachutes for there passengers?
Because; most passenger planes travel at 250+ miles per hour just to stay in the sky a 747 requires 500+ MPH. Usually, at altitudes around 20-35,000 feet where the oxygen is so thin you wouldn’t be able to breath and your lungs would freeze. To jump out of a say 747-400 the forces would rip you to pieces. Take a hard look at D.B. Cooper who hijacked a 747 after robbing a bank. He than put on a parachute and jumped out they never found his body, but did find some clothing and tatters of the money. Passenger liners are not designed for people to jump out of, period. The largest aircraft that I’ve ever jumped out of was a C-5 but that was at 5,000 feet, out of the tailgate, big difference.
