Pity the passengers of JetBlue Flight 191 this week – you know, the one where the pilot ran through the plane shouting the kind of words we all know don't go down well in a air-travel situations – namely "bomb" and "al-Qa'ida".

"Nobody knew what to do because he is the captain of the plane," Don Davis, a passenger, told reporters. But Davis, along with a number of other travellers on board, was flying to a security-industry conference in Las Vegas. Surely security professionals are exactly the kind of passengers who know what to do when their pilot goes bananas in the middle of a flight?

The bouncers around my way would, I'm sure, have brought the situation to a close with bone-crunching swiftness.
