Commercial Can Opener
Can you open up a commercial airplane door while it's flying at altitude?
With the recent instances of people trying to open airplane doors while in flight, I was just curious if it's possible. Surely there is some sort of locking mechanism or other failsafe device that won't allow the doors to be opened above a certain altitude.
The doors of commercial transports are usually "plug"-type doors that are pressed against their frames by internal pressure in the cabin. They open inward initially, so to open them you have to overcome the cabin pressurization. The pressure against the door in flight is often around 20 tons, so even if you manage to unlock the door, you can't move it unless the aircraft is depressurized.
Some aircraft also have flight locks on certain doors that prevent them from being opened unless the aircraft senses that it is on the ground.
A few smaller aircraft (such as some pressurized turboprops and small aircraft, not commonly used as commercial transports) do not have plug-type doors, and these can be opened in flight.
