Foggy FOD walk
Airmen from the 171st Air Refueling Squadron, Selfridge Air National Guard Base, Mich., conduct a Foreign Object Debris walk on the airfield where the KC-135 Stratotankers are parked as a dense fog rolls in, Jan. 4, 2023. FOD walks are designed for the clean-up of an area or flightline, retrieving trash, rocks, loose metal objects, or anything else that may be or could become a hazard to aircraft or personnel.
