> after all some normal passenger airports are a few thousand feet above sea level and we want the doors to work there
That doesn't make sense.
Regardless of airport altitude, when the pilot shuts off the cabin pressurization and opens the cabin vent[s] there will be zero pressure across the door.
The cabin doesn't "remember" the pressure at the last airport, because it's not a sealed volume. The air is constantly being replaced from outside, and the pressure is constantly being regulated.
