Brent Coffin, left, and Kalen Cole, 571st Aircraft Maintenance Squadron, work on an engine for A-10 Thunderbolt II, tail number 80-0264, at Hill Air Force Base, Utah, Sept. 28, 2021. The A-10 spent more than three years at Hill being restored by the 309th Aircraft Maintenance Group after a sustaining damage from a gun misfire over Michigan's Grayling Air Gunnery Range that forced the pilot to land without landing gear.
