It was the refusal to fly by a couple of Marine pilots that created the helicopter shortage, for instance helo five with the senior Marine on board that refused to continue on to Desert One and returned to the ship even though the co-pilot was protesting the action of turning back and aborting their mission.
I dont think you are readng too much on this thread.
My information comes from people actually on the mission, from their lips to my ears.
The Marines INSISTED they were to go on. They were told NO.
