Tech. Sgt. Kevin Harding, (second from the right), 60th Maintenance Operations Squadron discusses what happens if a KC-10 aircraft number one engine's drain mast is not properly serviced with KC-10 training course students. Currently six Airmen from Hickam Air Force Base, Hawaii and Kadena Air Base, Japan, are taking the two-phase course designed to train en-route maintainers how to recover and perform basic maintenance tasks and help move the aircraft through the theatre more efficiently.
