Climbing into a U.S. Air Force F-86 Sabre jet fighter. Photo is dated 13 July 1953, two days after Major Bolt shot down his fifth and sixth MiG-15s to become the only U.S. Marine Corps air Ace of the Korean War. He achieved the aerial victories while flying with the 5th Air Force as an exchange pilot. The original caption states: Major Bolt, who shot down six Japanese planes during World War II, has flown 89 jet fighter-bomber missions with the 1st Marine Aircraft Wing, which has been assigned only close support and interdiction missions in Korea. He has flown 37 Saberjet sweeps with the 5th Air Force, which is carrying the air war to the MiGs. Photographed by TSgt. Tom Donaldson. U.S. Marine Corps Photograph.
