Victor 90 left without one of the support members when Major Hopkins ordered Dr. Robert Serber of Project Alberta to leave the plane because the scientist had forgotten his parachute, reportedly after the B-29 had already taxied onto the runway. Since Serber was the only crew member who knew how to operate the high-speed camera, Hopkins had to be instructed by radio from Tinian on its use.
The aircraft failed to make its rendezvous with the remainder of the strike flight, which completed the mission without it. It did however arrive at Nagasaki in time to photograph the effects of the blast, then recovered at Yontan Airfield, Okinawa with both Bockscar and The Great Artiste.
It was originally assigned the victor number 10 but on August 1 was given the circle R tail markings of the 6th Bomb Group as a security measure and had its victor changed to 90 to avoid misidentification with actual 6th BG aircraft. On July 23, 1945, with Col. Paul Tibbets at the controls, it dropped a dummy Little Boy bomb assembly off Tinian to test its radar altimeter detonators.
On August 6, 1945, Big Stink was flown by crew B-8 (Capt. Charles McKnight) as a back-up spare but landed on Iwo Jima when all other aircraft in the flight continued on. The airplane was reassigned to crew C-12 (Capt. Herman S. Zahn) immediately following the Nagasaki mission, who named the airplane and had nose art applied.
Big Stink also flew 12 training and practice missions, and two combat missions to drop pumpkin bombs on industrial targets at Nagaoka and Hitachi, both flown by Classen and crew A-5. Big Stink was flown by more crews (9 of the 15) on operational missions than any other 393rd BS B-29.
After World War II it served with the 509th CG at Roswell Army Air Field. In April 1946 it was assigned to Operation Crossroads, and renamed Dave's Dream by its crew in honor of Captain David Semple, a bombardier who had been killed in the crash of another B-29 on March 7, 1946, near Albuquerque, New Mexico. Semple had been a bombardier in many of the 155 test drops for the Manhattan Project. On July 1, 1946, Dave's Dream dropped the Fat Man atomic bomb used in Test Able of Operation Crossroads at Bikini Atoll.
In June 1949 Big Stink/Dave's Dream was transferred to the 97th Bomb Wing at Biggs Air Force Base, Texas. It was converted to a TB-29 training aircraft in April 1950 by the Oklahoma City Materiel Area at Tinker Air Force Base.
It was subsequently assigned to:
The crew were joined by two British observers:
