On 18 December 1944, he flew in the left seat as the Airplane Command Pilot aboard a Boeing B-29 Superfortress nicknamed "Dixie Darling" (Serial #42-63413) Tail Code: A-Square-45.
It was one of 89 aircraft launched in a multi-group formation to bombard the Mitsubishi Heavy Industries Company and Aircraft Engine Plants near Nagoya, Japan. However approximately 80 nautical miles west of Iwo Jima, his aircraft was last sighted leaving the formation at a geographic location of 24 degrees +33 minutes North and 139 degrees +50 minutes East. Weather at the time was under-cast with a ceiling of 10,000 feet and less than 3 miles of visibility at sea level. His aircraft never returned to Saipan and was presumed to have been forced to ditch due to mechanical problems. A routine sea search failed to reveal any trace of the plane or survivors.
