Maintainers assigned to the 20th Aircraft Maintenance Squadron, Shaw Air Force Base, S.C., perform a foreign object debris walk prior to a Red Flag 15-1 training sortie at Nellis Air Force Base, Nev., Feb. 10, 2015. FOD is a hazard for aircraft and other precision equipment, because objects sucked into the air intake of jet engines can cause serious damage. (U.S. Air Force photo by Staff Sgt. Siuta B. Ika)
