Maj. Cody Clark, 433rd Weapons Squadron F-15 pilot, is greeted by Airman 1st Class Thatcher Gore, 757th Aircraft Maintenance Squadron Eagle Maintenance Unit crew chief, after a sortie in which aircraft 83-3014 hit 10,000 flight hours at Nellis Air Force Base, Nev., Jan. 25, 2017. Although the Air Force’s F-15 fleet is more than 30 years old, only a handful of the C/D/E aircraft are believed to be in the 10,000 hour club. (U.S. Air Force photo by Staff Sgt. Siuta B. Ika)
