Team Mildenhall maintainers push a KC-135 Stratotanker engine into place Jan. 24, 2014, on RAF Mildenhall, England. Each engine weighs approximately 5,000 pounds and takes several airmen and an engine trailer to move. Due to their weight, engine trailers and manpower are the easiest method for transporting engines across hangar floors. (U.S. Air Force photo by Airman 1st Class Preston Webb/Released)
