FOD Walk
Airman 1st Class Rafael Daniel, 51st Communications Squadron knowledge operator, displays the “golden bolt” found during the foreign-object-debris walk performed across the airfield of Osan Air Base, Republic of Korea, Sept. 29, 2015. Four golden bolts were hidden along the flightline as an added incentive, the finder of one these bolts would earn a day off.
