An unamed FBO that had a Can-Am spider promotion going on, one of the senior line-personel decided to ride it around on the ramp and run into a new Hawker....(doh)

Prior to my employement at my current company, a lineman decided to catch a brand new saratoga tail in on a post in the hanger, torquing the whole rear end of the airframe!!!

At an airport I used to instruct, a gentleman with his new G1000 C182 was taxing out of the hangers and was dragging the left wing-tip down the front of the hanger doors(it was a tighter allyway, but still!!!)

When I was at Purdue, the Beechjet was at IAD i think, and the line crew decided to drag another plane wing through the nose of the beechjet. They were able to patch it enough to get a ferry permit to bring it back to LAF.

I'm sure there's others, but yup, interesting stuff!!!
