Here is a good one.
A Captain for a major airline goes through security. He is wearing a tie tack that is in the shape of a handgun and is about the size of a nickle. Granted, this is not allowed by the company FOM, which allows an ALPA pin or a company provided tie tack, but this fellow is into handguns.
TSA says he can't go into the secure are with a handgun. He says it is only a tie tack made out of pot-metel. TSA takes it away from him. True story...
I fly with many pilots who flew fighters and like to wear a little F-16 or the like as their tie tack. So which is more dangerous? A handgun with 6 rounds for a revolver or up to 15+ for semi-auto, or an F-16 with a drum of 20MM and two sidewinders?
Obviously TSA is lacking in common sense. An F-16 tie tack can carry a heck of a lot more ammo! This clearly shows that the TSA training is lacking if they allow a fighter aircraft tie tack into the secure area!
