On May 29, 1945 took off from North Field on Guam piloted by 1st Lt. Marion C. Floyd on a bombing mission against Tachikawa on Honshū in Japan. The weather was clear. After the bombs were released, intercepted by Japanese fighters. This B-29 was hit in the no. 3 engine caught fire with flames as far back as the tail causing the bomber to begin a slight turn to the right downward and passed under the formation and last seen at 6:00pm. Gunners aboard other B-29s reported seeing two parachutes opening that were strafed by Japanese fighters as they descended. The damaged bomber was believed to crashed and burned at Tachikawa. When this aircraft failed to return it was officially listed as Missing In Action (MIA).

Fates of the Crew
Buttala survived and was captured by the Japanese and became a Prisoner of War (POW). He was detained with other Allied prisoners at Tokyo Military Prison. During the night of May 25-26, 1945 the prison was destroyed by fire during a B-29 fire bombing raid over Tokyo. Buttala died in the fire.

Recovery of Remains
Postwar, the remains of the crew were recovered from the crash site and transported to the United States for permanent burial.

American Graves Registration Service (AGRS) recovered 65 sets of remains from Tokyo Military Prison including 26 that were identified and 39 unknowns that were later buried at Fort McKinley Cemetery (Manila American Cemetery).

Due to the efforts of family members, during March 2022 and April 2022, the unknowns associated with the Tokyo Prison Fire were exhumed from Manila American Cemetery and mitochondrial DNA analysis tested by the Defense POW/MIA Accounting Agency (DPAA). On January 14, 2025 2nd Lt Justice J. Buttala was accounted for by the Department of Defense (DoD).

Memorials
Six of the crew, Cupp, Engfer, Floyd, Hollens, Perry, Sprague and Cupp were officially declared dead the day of the mission. Postwar, they were buried in a group burial at Jefferson Barracks National Cemetery at section 82 sites 4-5.
