Captain Frederick C. Bock and his C-13 crew flew The Great Artiste to Nagasaki on its instrument support mission, and landed with it on Okinawa at the conclusion of the mission.[5] It was the only aircraft to directly participate in both missions.[6] Enola Gay, flown by Captain George Marquardt's Crew B-10, was the weather reconnaissance aircraft for Kokura, the primary target on the Nagasaki flight.
