Airman 1st Class Sherman Purnell, 22nd Maintenance Squadron hydraulics specialist, removes a spoiler bypass valve Oct. 13, 2016, at McConnell Air Force Base, Kan. Spoiler bypass valves allow the operation of a KC-135 Stratotanker’s speed brakes to increase drag and safely decrease speed. (U.S. Air Force photo/Senior Airman Christopher Thornbury)
