Airman 1st Class Darrick Walker and Senior Airman Tim Street, 6th Aircraft Maintenance Squadron crew chiefs, wash the panels of a KC-135 Stratotanker jet engine, April 30, 2013, at MacDill Air Force Base, Fla. Due to Florida’s oceanic climate maintenance personnel must wash the aircraft regularly to minimize corrosion. (U.S. Air Force photo illustration by Senior Airman Melanie Bulow-Kelly/ Released)
