CNN.com - Knives, guns, fake bombs elude airport security - March 26, 2002

I guess I wasn't watching the news on March 26, 2002 because I missed this report: "WASHINGTON (CNN) -- Security screeners at 32 U.S. airports failed to detect most knives and simulated explosives -- and one of every three guns -- that federal investigators tried to smuggle past security checkpoints in tests after the September 11 attacks, a government official said Monday.

In hundreds of undercover tests conducted between November and February, security screeners missed 70 percent of knives, 60 percent of simulated explosive devices, and 30 percent of guns. Overall, screeners failed 48 percent of the time. "
