Prior to 1961, carrying a concealed weapon onboard a regulated U.S. air carrier was completely legal. From then until the 1974 Antihijacking Act, openly carrying a firearm was completely legal. Then in 1968 the Gun Control Act was passed as part of a wave of anti-gun hysteria. Most major airlines started banning the carrying of firearms in the cabin. Some of the regional airlines, such as Ozark Airlines, obviously did not as I have personally seen armed people disembarking planes like this:
I was a youngster but I remember clutching the chain link fence and watching the planes and the occasional armed man getting off of them in the late 1960's.
Note that from the Wright Brother's first flight until 1968 there were just three documented cases of hijackings in the U.S. In 1968 that number jumped to 31. In 1969 it jumped to 82. But I'm sure that's just a coincidence.
In 1974 Congress got around to formally banning the carrying of weapons on board aircraft. The number of hijackings had already decreased from the 1969 peak to between 20 and 40 per year. That number has pretty much stayed the same since.
So instead of offering training on defensive shooting inside aircraft or arming pilots the government decided instead to provide some security theater to make the nervous nellies feel better. And in 2001, 13 fanatics with box cutters killed 2,977 people including the 246 people on the planes who were, by law, disarmed. The heroes on board Flight 93 had to fight back with a drink cart because their government denied them the right of self-defense with more useful weapons.
There is some good news lately. With the rollback of many anti-gun laws in the country, places that were once banned for concealed carry are now open again. Today you can sit in a bar or restaurant in Florida, Virginia or Pennsylvania (though you can't consume alcohol) while carrying concealed. It's getting better for the legally armed.
But not airports and aircraft.
Which leads to stupidity like this:
This picture was taken by MarkofAFreeMan from the 4th floor mezzanine of the Orlando Airport Hyatt Regency while attending the Gun Rights Policy Conference. Inside the hotel and conference center concealed carry is perfectly legal per Florida law including on the mezzanines. Now, see that blue-green-grey carpet down there?
That's the Orlando International Airport terminal. If you're carrying concealed and your foot touches that carpet you've just committed a felony.
But you can stand up there where the picture was taken, fully armed and be completely within the law. Somehow having armed citizens standing right above the traveling public has not caused mayhem or "blood in the streets."
So tell me, in what world does banning carry on that carpet make sense?
