ELI5: Why doesn't every plane have parachutes for every passenger in case of emergency?
gpt
First. It would scare the passengers.

Second. Not everyone knows how to free fall, deploy a parachute in the right position, then land on the ground safely, it would be a nightmare explaining this on every commercial flight.

Third. It could be a liability in the case someone needs to use it and the parachute doesn't deploy correctly.

Fourth. Commercial airliners fly way at a very high altitude, the cabin has to be pressurized so opening a door is not feasible without repercussions and the air is very thin and hardly breathable.

Fifth. Ensuring the parachutes are in good working order would incur more fees that no one wants to pay for a flight.
