Not one of my own, thank goodness, but heard of a teeny-weeny helo pilot who dropped off a photographer at a landing site. Not wanting to waste any time he pushed the collective down and then opened the door for his passenger.
As the photographer climbed out, the shoulder strap from his camera bag caught under the collective lever. The helo back-flipped.
At least the pilot was still strapped in, otherwise it might have been difficult to explain
