How does one operate the emergency doors on an airplane? Could some crazy person open them in flight?
Obviously many people don’t pay attention to the flight attendants or read the briefing cards, which explain in detail how to work the doors. You should know how to do this. But in midflight, no, the doors won’t open. That goes for the smaller emergency hatches and the main exits. The hatches, usually found over the wings, are restricted by the outward-pushing forces of the pressurized fuselage. Like a drain plug they always open inward, and a person would not be capable of overcoming these forces until the aircraft is depressurized. The larger cabin doors are more complicated. Some operate manually, others mechanically. Secured by a series of locks, they also are subject to outward-acting pressure as in the case of the hatches, and/or sensors that do not allow movement while the plane is pressurized. You’ll notice that on the flat, shelf portion of the door — so alluring as a resting spot while waiting for the lav — it often says DO NOT SIT. While I wouldn’t recommend it, you could
