The latest interesting door story I read was in the June issue of Professional Pilot.

Apparently a mechanic had just replaced the VSI in a King Air and had the pilot take it up on a test flight. After the plane taxied in from the test flight, the mechanic attempted to board the plane with the engines still running (which is very doable in a King Air.) When he opened the door from the outside, the plane was still pressurized enough to force the door outward fast enough to hit the mechanic in the head and kill him.
