US airport security officers have confiscated a missile launcher from a passenger's luggage for the second time this week.
On Thursday, one of the military-grade weapons was located in a man's checked luggage at Baltimore/Washington International Thurgood Marshall Airport.
In a statement, Maryland fire marshal said it was "empty of any explosive hazard and was inspected by the US military for safety".
It had been brought back by a man who was travelling home from Kuwait and said he was in the military and had wanted to keep the weapon as a souvenir.
After being detained for questioning, he was allowed to catch his flight home and the missile was handed over to the state fire marshal for disposal.
On Monday, another US service member travelling home to Jacksonville, Texas from Kuwait had to turn over his missile launcher before being allowed to catch his flight.
The Maryland fire marshal recommended members of the military should look up the rules for commercial flights when they decide which souvenirs to bring home.
