What many may not realize, modern aircraft doors have an inward opening design. This causes them to be held, very firmly I might add, in place during pressurized flight. The cabin pressure is in addition to the inter-locking mechanism that is engaged during flight as well. Just a little fun with the math here..... Making some assumptions, let's say there is 8 psi cabin pressure (that's 8 Pounds per square inch). Now let's say the door is roughly 6 ft (72 in) by 4 ft (48 in) gives you an area of 3456 sq. in. At 8 PSI, thats over 27.5 *TONS* of force holding that door closed. That's in addition to the lock. Now, the witness said the 3 guys that helped were big guys. This hispanic dude must have been the friggin' Hulk to make any progress on that door. Soooo... Richer Brat - relax, watch your movie, munch on the peanuts and enjoy your flight. :-) PS I am not a structural or aerospace engineer so please forgive me if the math is not perfect ;-) Good point JB!

Doors do not open and cannot be opened during flight on pretty much any modern airliner.
