Back in the days of old...back when Bert had hair....when we had unlimited amounts of flying time devoted to touchdown autorotations in UH-1 B's and D's....we used to have contests (all informal and covert mind you). The B model was the most fun...sat lower and did not seem to mind the sliding as much.
Winner was who could land in the shortest ground run...the longest ground run...with specified touchdown points...ending points or both....hovering auto's followed by a liftoff and another hovering auto following pedal turns of various duration.
None of those maneuvers involved the use of a cookbook....and we did not ever bend a machine while engaged in such shenanigans. Might have worn out some skid shoes by the pallet load...but no damaged aircraft.
I was accurately quoted....Helicopter Pilots live and die by Nr....or the lack of it.
