So you think the Second Amendment should be interpreted to guarantee a right for passengers to bring loaded guns onto commercial airplanes?
There's a position with "broad appeal" - NOT!!
It wasn't an issue up until the 1960's. Heck, even into the 1970's on some carriers. Why the fear and hysteria now? Have you been watching too many old Twilight Zone or James Bond movies? Afraid one bullet will cause massive decompression? Even if it drops the AC out of the sky from an extremely "lucky" hit on the avionics compartment, how less dead are you than if the terrorists crash you into a building instead? Further, there are "aircraft safe" rounds that could be mandated by the airlines insurance agreement for those wishing to carry while on board. Check your ammo at the gate, load your frangible "smart" rounds, and any terrorist wanna be's end up on the bad end of the stick.
