JOINT BASE BALAD, Iraq -- Tech. Sgt. Fred Williams secures rope around the Mobile Aircraft Arresting System cable to the runway here July 20 as part of an annual certification of the system. This system is used to catch aircraft during take off and landing emergencies. Securing its cable to the runway prevents the cable from flying up and damaging the aircraft. Sergeant Williams is the 332nd Expeditionary Civil Engineer Squadron's NCO in charge of barrier maintenance and is deployed from Kadena Air Base, Japan.
