U.S. Marine Fighter Attack Squadron 121 conducts a hot reload on an F-35B Lightning II at Marine Corps Air Station Iwakuni, Japan, on April 6, 2017. Marines loaded the F-35 while the pilot remained in the aircraft with the engine running. This training ensures the aircraft can reload as fast as possible if need be. (Cpl.
