I don't understand... How would that work? The doors open to the outside, and the pressure is higher inside, so if anything, the pressure differential should help opening the door?No. The cabin pressure differential with the outside air makes it impossible.
In fact, even if the pressure was the same on both sides, the speed of the air outside should suck the door out (it's the exact same principle that allows chimney to work, and which tear away objects in a storm)
