It dawned on me that some folks may not have the benefit of ever knowing a fighter pilot so I will explain what I meant by the old saying. The reason you can't teach them very much is because they already know it ALL!!!
My experience is that one could extend that maxim to all aviators. Pilots tend to be a heady bunch. One year while riding as a passenger in my Dad's plane we stopped to refuel in Brunswick GA, where all the local EAA members were wearing T-shirts that said:
"I'd like to die peacefully in my sleep, like Grandpa did... not screaming in terror like the passengers in his airplane."
Hanging out with Dad and his flying buddies there was much such humor. Any discussion of aviation death would invariably conclude with someone saying, "and the really sad part is that the pilot ruined a perfectly good airplane".
I know a woman whose husband flew a Mooney, which is a high-performance single engine plane that is even harder to fly than some others. This woman would frequently travel with her husband but had never touched any of the controls in her life. Well, her husband had a heart attack and died when they were about 5000 feet up.
She didn't even know how to turn on the radio for guidance. She didn't know about putting the landing gear down. Somehow, she crash-landed the plane and crawled in bitter cold, with all kinds of broken limbs, about a mile to a farmhouse. She survived, wrote a book about it.
Then there's my buddy Don (Snakeman) T, who was a Forward Air Controller in Vietnam. When discussing the inline twin-engine Cessna that some of his buddies flew, he would say that if one engine lost power, the purpose of the second engine was to take the pilot to the scene of the crash. I've heard helicopter pilots make the same joke regarding the purpose of auto-rotation if the engine failed.
