[thucydides]

If the pilots had been armed, or if concealed carry passengers with a proper permit were allowed, this would never have been attempted, let alone happened.

I sympathize with RKBA, but I draw the line on airplanes. Your average permit holder shouldn't be able to carry a gun onto a plane where he/she'd have a captive group of 50-400 people at the potential point of a gun, and the use of a massive, directable bomb at his/her disposal.

If your answer is that some *other* permit holder would draw to counter terrorism, I'd point out that an airplane is not the ideal place for a shootout.

What to do:

1- Keep all weapons out of the cabin, as far as possible
2- Have a trained air marshal service (don't hold your breath, 'cause you'll see one now).
