Airmen in the cockpit
Tech. Sgt. Jeremy Pressley, of the 33rd Maintenance Operations Squadron, is the first maintainer to complete an F-135 engine run. He will be an instructor for next few maintainers chosen to go through the F-35A engine run course. Having maintenance personnel conduct engine runs frees up pilots for training missions and allows the jets to get fixed faster. (U.S. Air Force photo/Staff Sgt. Bruce Ferris)
