U.S. Air Force Staff Sgt. Alec Dyer, a 354th Maintenance Squadron aerospace propulsion craftsman, checks to make sure the engine of an F-16 Fighting Falcon has enough room to be pulled out Aug. 12, 2016, during RED FLAG-Alaska 16-3, in the phase shop at Eielson Air Force Base, Alaska. It is important that the engine has enough clearance when it is being removed from the aircraft. (U.S. Air Force photo by Airman Isaac Johnson)
