10th Flight Test Squadron
Aircrews from the 10th Flight Test Squadron work closely with Oklahoma Air Logistics Center maintenance professionals during pre-flight inspections on aircraft fresh from the depot at Tinker Air Force Base, Okla. Here, engine mechanic Matt Jennings, from the 564th Aircraft Maintenance Squadron, along with KC-135 Stratotanker pilots Maj. Kelly Buck (left) and Maj. John Cary are running a meticulous pre-flight inspection that may take up to three hours. Following that, the aircraft will be flown to ensure its air-worthiness. (U.S. Air Force photo/Margo Wright)
