Staff Sgt. Jairusnoel Ticsay, 374th Civil Engineer Squadron electrical power production craftsman, ensures precise spacing in between cable donuts prior to the annual certification test of the aircraft arresting system at Yokota Air Base, Japan, April 29, 2020. The rubber donuts elevate the cable to the proper height, providing proper distance for an aircraft to latch onto the cable in the event of an emergency landing.
