Members of the 509th Maintenance Squadron jet propulsion flight pose for a group photo on July 9, 2019, at Whiteman Air Force Base, Missouri. The jet propulsion flight works daily to run diagnostic tests and perform regular maintenance on F-118 engines, which power the Whiteman AFB fleet of B-2 Spirits. Thanks to their efforts, Whiteman AFB has the highest engine readiness rate across the active-duty Air Force. (U.S. Air Force photo by Staff Sgt. Kayla White)
