Mythbusters tested the Hollywood `bullet through the window passengers sucked out` scenario (by pressurizing an airliner and shooting a bullet through a window) and determined that this does not happen.

Yeah I saw that video, however their experiment, although does take into account the pressure differential between the inside and the outside of the plane, fails to simulate the great speed that airliners fly at, which I guess is another serious factor to take into consideration.

On 24 Feb 1989, United Airlines flight 811 a Boeing 747-100 experienced an explosive decompression as it was climbing between 22,000 and 23,000 feet after taking off from Honolulu, Hawaii, en route to Auckland and Sydney. The airplane made a successful emergency landing at Honolulu and the occupants evacuated the airplane. Examination of the airplane revealed that the forward lower lobe cargo door had separated in flight and had caused extensive damage to the fuselage and cabin structure adjacent to the door. Nine of the passengers had been ejected from the airplane and lost at sea.

Yeah, I mentioned this accident myself in the first post, but in this case the cabin floor partially collapsed, and seats are attached to it. What I’m wondering is what would happen if there was a massive decompression but without the cabin floor being damaged.
