Keep the firearms off of the plane, unless you are some sort of law enforcement designated to carry a firearm on your person at all times. You think you could take the boxcutter guy out in front of you, but what happens when the guy sitting behind you whips his out and slits your throat? The terrorists would then have a firearm.

A bullet hole in a pressurized cabin at 30,000 feet is a bad, bad thing. But what if they have a gun? Bum rush his ass! Eventually he'll have to reload.
