Transportation authorities said a passenger inadvertently carried shotgun shells onto a plane at Milwaukee's airport Monday.
As the plane was getting ready for departure, the pilot came on the intercom and said the plane had to return to the gate because a passenger had told a flight attendant he had the shells in his carryon bag, said another passenger on the flight, Doug Bell, of Hales Corner, Wis.,
Bell said the man got off the plane and TSA agents searched the storage compartment above his seat.
He said he thought the whole thing was an honest mistake but worried the TSA didn't take the incident seriously enough.
"The same TSA that let him get through is the same TSA that said, 'Well, we rescanned him and let him reboard,'" Bell said. "It just doesn't make sense."
The TSA statement said agents turned the ammunition over to local police. The man was rescreened and allowed back on the plane.
The flight was delayed about 45 minutes.
