Pilot got too close with rear rotors as hovered and the touched. Dunno what it looked like happening from outside, but it tore off the whole upper tail section of our ship and we fell several feet.

I was an Army pilot in a much easier time (85-90). Worst damage I ever did was while hovering an AH-1f cobra at a farm in Germany. Blew over the farmer’s motorcycle (he got paid a few hundred marks in “maneuver damage” compensation)
