100th CES maintains safety barriers
U.S. Air Force Tech. Sgt. Christopher Marrs, left, 100th Civil Engineer Squadron NCO in charge of power production from Eugene, Ore., and U.S. Air Force Staff Sgt. Kyle Dulin, 100th CES firefighter from Redondo Beach, Calif., lead a barrier testing operation April 17, 2014, on RAF Mildenhall, England. The Airmen conducted rewind operations and gave signals to personnel in shacks. There are two shacks housing the machines that reel in the barrier, one on each side of the runway. They use a two-person concept to ensure safety. (U.S. Air Force photo by Gina Randall/Released)
