An undercover agent was testing the efficacy of security screeners in Dallas. In five tries, the gun wasn’t detected once.

The source said the undercover agent carried a pistol in her undergarments when she put the body scanners to the test. The officer successfully made it through the airport’s body scanners every time she tried, the source said.

“In this case, where they had a test, and it was just a dismal failure as I’m told,” said Larry Wansley, former head of security at American Airlines. “As I’ve heard (it), you got a problem, especially with a fire arm.”

The employees working the scanners weren’t disciplined and are still working the scanners.
