LANGLEY AIR FORCE BASE, Va. -- Staff Sgt. Ralph A. Williams, 1st Operational Support Squadron aircrew flight equipment craftsman, helps Staff Sgt. Jose Camacho, 27th Fighter Squadron aircrew flight equipment craftsman, make tail covers for the F-22A Raptor here June 24. The covers prevent overspray from getting on the skin of the aircraft and hindering the Raptor’s stealth capabilities, as well as, helping in the application of low observable materials to the aircraft.
