Special Agent Frank Burton said it wasn’t immediately clear if the tip that led to the recall of Flight 1267 involved a specific person or a specific flight.
Transportation Security Administration spokesman Dave Castelveter said the airplane returned "due to a report of a suspicious item on board."
Video from TV stations showed law enforcement officials removing a person from the flight and police dogs on the tarmac at Philadelphia International Airport. Passengers were bused away as a slew of law enforcement vehicles surrounded the aircraft.
The airplane bound for Dallas-Fort Worth International Airport had 69 passengers and five crew members on board, airport spokeswoman Victoria Lupica said. It left Philadelphia around 8 a.m. and returned in less than an hour, she said. The jet was over central Pennsylvania when it turned around, according to the flight-tracking website FlightAware.
No other flights were affected, Lupica said.
US Airways did not immediately return a phone message seeking comment. Philadelphia police referred all calls to the FBI.
