Hydraulics Airmen keep tankers in the sky
U.S. Air Force Staff Sgt. James Harris, 100th Maintenance Squadron hydraulics technician from Abilene, Texas, prepares to service surge boots within a KC-135 Stratotanker boom Aug. 11, 2015, on RAF Mildenhall, England. Surge boots are rubber-like sleeves that run the length of the fuel tube, used as a way to prevent damage during fuel surges when the boom disconnects from the aircraft it is refueling.
