ELLSWORTH AIR FORCE BASE, S.D. -- Airmen from every career field participate in a foreign object debris walk, June 7. The FOD walk is a simple way to bring all of Ellsworth's Airmen together and help keep the flightline free of potentially hazardous debris which could cause millions of dollars worth of damage to a jet.
