SOUTHWEST ASIA -- Tech. Sgt. James Kehoe (right) troubleshoots a discrepancy on an F-16C Fighting Falcon with his son, Senior Airman Travis Kehoe. They are Airmen with the Vermont Air National Guard's 158th Fighter Wing. The memory of Marine Cpl. Mark Evnin, a family friend who was killed in action last year, is what puts the fire in their fight. (U.S. Air Force photo by Staff Sgt. Colleen Bushnell)
