Feds probe SAM fired at airliner report
WASHINGTON, Dec. 2 (UPI) -- FBI agents and Homeland Security officials have been investigating the report of a possible missile fired at an American Airlines plane taking off from Los Angeles International Airport.

Sources told ABC News in Los Angeles that the pilot of American Airlines Flight 621, en route to Chicago, radioed air traffic controllers after takeoff from LAX. He told them a missile had been fired at the aircraft and missed.

The plane was over water when the pilot said he saw a smoke trail pass by the cockpit.

FBI agents believe it was a flare or a bottle rocket, but say they may never know if that's what it actually was, KYW Newsradio 1060 reported.
