Were the general public allowed to bring guns onboard, the victim is much more likely to be someone listening to music so loud it can be heard several rows away, despite headphones; or an armrest-hog; or a passenger moving another passenger's overhead luggage to fit her/his own in; or any of dozens of scenarios - i.e. the normal, everyday little annoyances of air travel - than to ever be a hijacker. No, it's not opinion. These incidents occur daily on flights. How many domestic flights have been attacked by terrorists in this century? Compare that to the over 100,000,000* domestic flights in the last ten years.

I don't doubt the number of flights.
Did you know that there has not been one case of somebody with a CCW commiting a crime with a gun? Not one charge of 'shooting the wrong guy' or ' oops, my mistake' ....Your comment that an american citizen lawfully armed with a ccw permit would shoot someone over an armrest borders on the absurd. Frankly, it is absurd, because it has never happened. It has never happened on a plane, a bus , a train, a bicycle, or on horseback, or walking down the street. Never. Period.
You can be anti second amendment if you want. But it does not really pertain to the issue we have been discussing now does it.
