Hangar Accident
There was a Delta DC-9 aircraft that hit the hangar many years ago but not by a pilot. Mechanics were doing a layover check which requires a cross tie relay check. This check requries the ground control cbs pulled to check the system. The mechanic did the check but forgot to reset the cbs. They then taxied the aircraft to the hangar on the other side of the field. With the cbs pulled only brakes available are accumulator pressure. They ran out of pressure at the time they reached the hangar and hit the door, which by the way came off the track. They were fortunate that the doors did not fall down.
