Unless you want to be a pilot. Then you have to be intelligent and handsome.
Wrench lead, wrenches, flight crew, design engineers and last pilots. That is the order of common sense, and the order of folks you question to get real information.
I know many pilot jokes, but I only know two that are not fairly obscene.
"How do you know if someone is a Naval Aviator? ... Wait five seconds and he'll tell you."
"Piloting used to be a real job. Now, the pilot feeds the computer, and the computer bites the pilot if he touches anything."
