And, nearly a dozen years after 9/11, it's happening a lot more often.
In the first six months of this year, Transportation Security Administration screeners found 894 guns on passengers or in their carry-on bags, a 30 percent increase over the same period last year.
The TSA set a record in May for the most guns seized in one week - 65 in all, 45 of them loaded and 15 with bullets in their chambers and ready to be fired. That was 30 percent more than the previous record of 50 guns, set just two weeks earlier.
