U.S. Air Force Senior Airmen Daniel Tomasek, 8th Civil Engineer Squadron electrical power production journeyman, signals his counterparts while reeling in the barrier tape on the aircraft arresting system at Kunsan Air Base, Republic of Korea, Sept. 9, 2017. The nylon barrier tape is woven into a rubberized material similar to that found in a golf ball which gives it elasticity. The material must be reeled in on its 66-inch spool properly to ensure that when an aircraft’s hook catches the steel cable the tape can extend a few feet before bringing the out-of-control aircraft to a safe halt.
