FOD walk
Members of the 18th Wing participate in a Foreign Object Damage (FOD) walk on the Kadena AB flightline Nov. 12. The purpose of FOD walks is to keep the airfield clean and free of damaging debris such as aircraft and vehicle fasteners, rocks and any hard or soft objects that can damage an aircraft engine or airframe.
