721st AMXS Airmen keep a bird in the sky
U.S. Air Force Airmen assigned to the 721st Aircraft Maintenance Squadron prepare a C-17 Globemaster III engine for removal at a hangar on Ramstein Air Base, Germany, Oct. 27, 2017. After removing the faulty engine, the maintainers lift the new engine in its place and bolt it to the aircraft. The faulty engine then gets sent to a facility where technicians diagnose the issues it has and refurbish it so it is operable again. (U.S. Air Force photo by Senior Airman Devin Boyer)
