Can you open a 747 door in flight?
Opening an aircraft door is impossible while the plane is at cruising altitude or above 10,000 feet due to air pressure. However, as the plane gets lower, experts say it is possible for a door to open as the pressure outside equalizes with the pressure inside the plane.
