Air Force Staff Sgt. Matthew Moore and Airman 1st Class Nathanniel Cones, 97th Operations Support Squadron airfield systems technicians, perform a 100-watt alignment on the transponder for the tactical Air Navigation System, Aug. 24, 2015. The alignment is important so the system does not give erroneous readings, which could cause equipment shutdown and endanger aircraft. ( Air Force photo by Airman 1st Class Megan E. Acs/Released)
