Tech. Sgt. Jeremy Thompson, a propulsion systems craftsman assigned to the 451st Expeditionary Aircraft Maintenance Squadron, Kandahar Airfield, Afghanistan, applies a liquid polymer to a C-130J Hercules propeller damaged during a mission Aug. 2, 2010. Sergeant Thompson, deployed from Little Rock Air Force Base, Ark., will sand the propeller to the proper contour once the polymer has been allowed to set within its recommended time.
