Officials: Pennsylvania man says he 'forgot' about loaded gun found in carry-on at the airport

Man says he 'forgot' about loaded gun in carry-on after being stopped at airport, according to officials.

An alleged lapse in memory could end with an even more expensive trip to the airport for one Pennsylvania man.

Officials say a 9mm caliber handgun loaded with nine bullets was found inside his carry-on bag at Harrisburg International Airport on Monday.

TSA reportedly spotted the gun and ammunition in the checkpoint X-ray machine, then alerted police.

The man, who is from Reading, reportedly told TSA officers that he "forgot he had the gun with him."
