Isaac Balaun, 55th Aircraft Maintenance Squadron aircraft mechanic, washes the engine of an RC-135 V/W Rivet Joint aircraft Aug. 20 inside of the Bennie Davis Maintenance Facility, Offutt Air Force Base, Nebraska, as it undergoes a thorough cleaning. A small team of maintainers can spend hours scrubbing and hosing the plane until it is clean. (U.S. Air Force photo by Josh Plueger/Released)
