Crashaxes
Fire axes ... used for all sorts of things.
I was told a story that some pilots, getting really p*ssed off with having to submit to security checks removed the axe from the aircraft and put it in their nav bags.
Went through security before flight.
Gorillas went into action refusing to allow the offensive weapon aboard.
Pilots sat down and said, "Plane can't go without it... give it back"
Tea 'n bickis for a couple of brave inventive coves.
Good on'em.
