Authorities busted a twenty-nine year old man with explosives Thursday morning at the Philadelphia International Airport.
The Pennsylvania man, was reportedly trying to board a plane bound for San Francisco, carrying a plastic bottle filled with explosives.
Investigators say the bottle contained powder used in fireworks.
Sources say a federal background check shows no initial ties to any terror groups. The man reportedly has told authorities he was "fooling around" with the explosives and forgot they were in his backpack. No flights have been delayed, and the airport has not been shut down.
