Delta passenger throws coffee, attacks air marshal during flight
". . . Passenger Martin Nicholls . . . added everyone on the flight was growing “very concerned because, I thought, we’re at 30-odd thousand feet over the sea. What if she tried to open the door ?” . . . "
No worry Martin. The only way she could open a door is if the cabin was no longer pressurized.
The cabin is pressurized to an equivalent altitude of about 8000 feet. The pressure differential between 8,000 feet inside and 30,000 feet (very, very, very low pressure) outside the airplane is way, way, way, to high for anyone to be able to open the door at 30,000 feet. Note too that airliner doors open into the cabin so that enormous pressure differential keeps the doors closed.
