Two years ago, all it took to bypass airport security was filling out a form:

Grant was flying from Boston to San Diego on Jan. 1, 2007, when he approached an American Airlines ticket counter at Logan International Airport and flashed a badge he carries as a part-time assistant harbor master in Chatham, according to federal prosecutors.

Grant, a medical supplies salesman, also filled out a “flying while armed” form and wrote that he worked for the Department of Homeland Security, prosecutors said.

[…]

He allegedly did the same on his return trip to Boston three days later.

But this time, according to court documents, he was invited into the cockpit, was told the identity of the two air marshals on the flight, and was informed who else on the plane was armed, which raises security concerns.
