340th Aircraft Maintenance Unit aircraft maintenance
Tech Sgt. Ryan Riley wipes sweat from his brow while he and Airman 1st Class Connor Sweeney work together to adjust the aircrafts boom pod shaft Aug. 5, 2014, at Al Udeid Air Base, Qatar. Airmen who perform maintenance on the flightline 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. Sweeney is a 340th Expeditionary Aircraft Maintenance Unit hydraulic systems craftsmen. (U.S. Air Force photo/Staff Sgt. Vernon Young Jr.)
