Airman 1st Class Jordan Gomez, 28th Aircraft Maintenance Squadron crew chief, sprays down a B-1 bomber, Jan. 16, 2013 at Ellsworth Air Force Base, S.D., as part of the aircraft’s maintenance schedule. Aircraft are washed every 120 days, or upon return from deployment, to ensure dirt doesn’t build and make working on the aircraft easier.
