A passenger on a New York-to-Cairo flight has been detained in Egypt after he tried to pass through customs there with what CBS 2 News of New York calls an "incredible weapons cache." The New York Post tabloid also picked up on the story, writing the EgyptAir passenger "flew from Kennedy Airport to Cairo with a mini-arsenal of two pistols, 250 rounds of ammo, two swords and 11 daggers in his checked bags … ." Still, U.S. officials say that even though the passenger violated regulations by not declaring the items, there was no security lapse. U.S. flight rules allow firearms to be checked in a passenger's luggage, though the passenger is required to declare them when checking the luggage. "Transporting firearms within the U.S. in checked baggage is permitted if properly declared to the airline," the TSA says in a statement, according to AFP.
