Senior Airman Jason Senter, who is deployed from the 932nd Civil Engineer Squadron, Air Force Reserve, installs cable spacers on the mobile aircraft arresting system, (MAAS) during a two-week maintenance overhaul at an air base in Southwest Asia. Senter is assigned to the 380th Expeditionary Civil Engineer Squadron. The MAAS is an emergency braking system for tail-hook-equipped aircraft. It is used in emergency situations when a fighter aircraft needs assistance coming to a full stop after landing. This occasionally occurs due to mechanical failures beyond the pilot's ability to correct prior to landing. (U.S. Air Force photo/Tech. Sgt. Patrick Mitchell)
