Pilots and air marshals only, and maybe flight crew if, and only if, seriously trained. Private people are good people, but one bullet through the aircraft could be serious and dangerous. Many Negligent Discharges do happen, and I would not want one while in the air.

I understand, but again..........how often do possessors of CCW licenses participate in "inadvertent firearms discharges"? Can't swear to it, but I'd guess "damned few". The keys are training.......and the character of the individual entrusted with such a license.

BUSSE STEALTH HAWK The Stealth Hawk from Busse Combat Knives is a unique professional knife developed for police, military, and SCUBA applications where detectability, magnetism, conductivity, or spark generation might prove detrimental to the mission. It weighs only 3 ounces, and is invisible to metal detectors. The material utilized in this blade is MP45. Nothing comes close to the strength and durability of this high-tech laminate. Combining this futuristic material with age-old swordmaking skills, the result is a synthetic “Damascus steel”. Each Stealth Hawk knife is hand ground and hand-made; no injection molding here. Solid one-piece full tang construction. The handle is wrapped with paracord. The blade is 75% large serrations for impressive cutting power. The tip of the blade is shaped like a bullet; this tip geometry provides superior penetration when striking hard objects with less tip damage than traditionally shaped points. This knife can be pounded through steel drums, car doors, wood planks, etc. without damage. The cutting edges can be brought back with sand paper. Blade length: 41/2". Overall length: 9 1/2". Blade thickness: 1/4". Weight: 3 oz. Very limited quantity left—no more will be available once these are gone! A special Kydex quick-draw sheath for the Stealth Hawk is also available.

could be this is what they used?

Also........ (not to appear as if I'm "picking" on you :) )...........the underlying concept here is "deterrence". IOW, my theory is that such a policy could help ensure that no weapon would ever have to be pulled inflight.

Attempt a hijack, you might be faced with ten or twelve handguns pointing at your skull. Pretty damned effective deterrent, I'd think. Same reason the average robber would avoid robbing a "cop bar".
