FBI: No Explosives On D.C. Bound U.S. Airways Flight

Federal investigators found no explosives aboard a plane that touched down at Regan National Airport in Washington D.C. around 1 p.m. EST, a FBI spokesman said in a statement.

Authorities said a person phoned the U.S. Airways ticket counter at James M. Cox International Airport in Dayton, Ohio. The threat shutdown the airport for 20 minutes Sunday.

Flight 2596 landed safely in the nation's capital but was taxied and parked away from its scheduled gate after landing, FBI officials said.

Passengers were being interviewed by the bureau's National Capital Response Squad, an elite unit which handles terrorism.
