Airmen in the 364th Training Squadron's hydraulics course work on one of two relatively new C-130 trainers the squadron brought in as part of an update to the course. Work was begun on revamping the course in 2013 when new instructors realized they were teaching the same materials they were taught as Airmen in Training years ago. The new course was validated in May. (U.S. Air Force photo by John Ingle)
