I read cowboybooter's post to my dad who was in aircraft maintenance with the Air Force for 24 years. He thought it was really funny! He came by the house last night and brought the following with him. It's a paper one of his co-workers typed up around 1966 when my dad was stationed at Charleston Air Force Base. He was with the 444th Fighter Interceptor Squadron (Air Defense Command) at the time.
The parts in
italics are things he had to explain to me.
