Not so much of an airport annoyance, but a flew airplane quandaries I have when I fly...
What if the mechanism on the wing that provides lift and drag, malfunctions during the initial rise and the plane keeps ascending until the plane is too high in the air and the engines stall?
What if the screws on the wing come undone?
What if the engine explodes? What if the screws on the engine come undone and it falls off?
What if landing gear malfunctions and the sensors don't pick up on it?
What if the pilot decides he doesn't want to live anymore?
What if a cracked out pilot of another plane flies into the plane I'm in?
What if the latch on the door breaks at 35,000 feet?
I would rather drive.
