FOD Walk
Airmen at Luke Air Force Base, Ariz., walk the flight line looking for foreign object debris during a Wing FOD walk, Sept. 27, 2012. By performing a FOD walk, the Airmen help to ensure that the flightline is free of debris that may cause damage to the F-16 Fighting Falcons that fly at Luke. (U.S. Air Force photo by Staff Sgt.
