Wiping sweat from his brow, Tech Sgt. Ryan Riley, along with Airman 1st Class Connor Sweeney, works to adjust a KC-135’s boom pod shaft Aug. 5 at Al Udeid AB, Qatar. Airmen who perform maintenance on the flight line here endure stifling heat, sand and wind to keep air refueling aircraft and a multitude of other airframes taking off and landing day and night.
