Flying on a plane comes with it's own mental images, our brains play mean tricks on us from time to time. One of those tricks my brain has played on me is always "What if the door flies open?"
Hollywood has done this scenario on screen before from "Charlie's Angels" (yes Charlie's Angel's):
"Iron Man 3" had a scene where a hole is ripped into Air Force One and people fly out:
So yeah, IRL that would be scary! I wouldn't want it to happen to me!
On a flight from California to Idaho, a women claiming to be God, tried to actually open the door on a United flight, and was gratefully subdued by passengers who tied her up until they landed safely on the ground!
