Propulsion flight keeps jets in the Air
SPANGDAHLEM AIR BASE, Germany – U.S. Air Force Staff Sgt. Michael Mosley, 52nd Component Maintenance Squadron aerospace propulsion craftsman from South Orange, N.J., and Staff Sgt. Michael Murphy, 52nd CMS aerospace propulsion craftsman from Dallas, check fluid levels and engine vibrations of an F-16 fighting falcon fighter aircraft engine Aug. 8, 2013. Oil samples are taken from the engine to look for any debris that might be inside. Airmen also look for fuel and oil leaks during inspections.
