I recall reading a shortly-after-9/11-interview with a Continental pilot who was left unidentified by the reporter so the pilot wouldn't get in trouble; the pilot's idea was to have EVERYBODY on board the plane armed with a knife -- if they didn't bring their own, they could pick one up from a box at the gate. "If somebody tries to hijack my flight," he said, "I want them to have to deal with 200 angry people carrying knives."
