Unfortunatly it happens all too often. In the past year I have had my aircraft pushed into the back wall of a hangar and a taxi drive into my wing while he was leaving the ramp.

I have seen a counter weight drop down on the wing of a 210 and a tug punch a 3 foot hole in the side of a Citation. Perhaps the oddest was when a King Air was parked outside a bifold door. The door was opened without looking to ensure it was clear outside and the door picked the plane up by the tail.
