C-130's can back outta their parking spots. I have been in several that backed up on the ground. I think that qualifies. they also reverse when they land to help reduce the rollout after getting it on the ground. i think it would be a disaster if it happened in flight though. not sure, but i think there is some kind of failsafe that prevents that.
Can you say "drop like a rock?"

Yeah, there is a failsafe that keeps that from happening. I used to work on 130's for the Air Force, and I had the same question. Engine troops and crew chiefs cleared that up for me.
