Airman 1st Class Anjo Betitia, 74th Aircraft Maintenance Unit crew chief, sprays the wing of an A-10C Thunderbolt II, Feb. 25, 2019, at Moody Air Force Base, Ga. A-10s require a wash every 180 days, or 1,000 flying hours, in order to control corrosion and grease build up within the aircraft. (U.S. Air Force photo by Airman 1st Class Eugene Oliver)
