Airman 1st Class Jake Dromgold, 23d Aircraft Maintenance Squadron 74th Aircraft Maintenance Unit crew chief, washes under the wing of an A-10C Thunderbolt II, Aug. 28, 2017, at Moody Air Force Base, Ga. Maintenance procedures require that A-10s are washed at least every 180 days to prevent maintenance issues and safety hazards to the pilot. Since strong chemicals are used to clean the aircraft Airmen must wear personal protective equipment. (U.S. Air Force photo by Airman 1st Class Daniel Snider)
