Dyess Airmen conduct a Foreign Object Debris (FOD) walk down the flightline Sept. 9, 2013, at Dyess Air Force Base, Texas. FOD walks are conducted to minimize possible damage to aircraft from debris. FOD can range from missing tools to pens and pebbles. On Aug. 29, Dyess reached a new pinnacle of FOD prevention; 1,500 days without a chargeable FOD incident. (U.S. Air Force photo by Staff Sgt.
