What aircraft established a distinction of having the highest operational rediness figures with the least amount of maintenance man hours during the Viet Nam Campaign.
Your question needs to be narrowed down quite a bit. Several different aircraft have claimed this distinction under various conditions and time frames. Are you talking about every aircraft that ever took to the air, only military, only civilian, WW-I, WW-II, Korea, Viet Nam, later wars, USAF, Navy, props, jets???
