  • You should know that it is physically impossible to open the cabin door of an airliner at altitude. Cabin doors are designed so that one must first pull the door in to unlatch it. This requires overcoming a pressure differential of 7 psi or more. Assume a tiny 2’ x 5’ door. That equates to a surface area of 2’ x 5’ = 10 sq ft => 10 sq ft x 12" x 12" = 1,440 sq in => 1,440 sq in x 7 psi = 10,080 lbs of force. So the only way the cabin door is coming open is if the cabin is not pressurized, which normally means the plane is climbing to altitude after takeoff or descending for landing. If you are at altitude and the cabin is not pressurized, you will soon pass out unless you are wearing an emergency oxygen mask. The lack of pressure differential means no one would be sucked out of the plane; it would just be extremely windy.

    So if someone tries to open the cabin door in the middle of your flight at altitude, just sit back and enjoy the show.
