I was studying a report of an arriving Beech 1900C that collided with a departing King Air on intersecting runways at Quincy IL - everyone died because the airstair door (only one on this plane) could not be opened either from inside or out. When I saw that raised flange with the right rear door still firmly in the frame, I shuddered. These regional airliners have steeply curved fuselages and it doesn't take much dinging to make them stick in their frames. After the Beech crash, the FAA issued an urgent advisory and the door was apparently redesigned. I'll guess that many of the casualties here resulted from that stuck door in the back. Horrible!
This is a bad year - I'm getting pretty tired of seeing mangled and charred airframes. Drive safely y'all.
