Narrative:
Boeing KB-29M Superfortress 44-70024: Delivered to the USAAF 9 April 1945. Modified to KB-29M at Boeing, Wichita, Kansas. Assigned to 307th Air Refueling Squadron, 43rd Bomb Group, Davis-Monthan AFB, Arizona

Written off (destroyed) 16 November 1950: The KB-29M aircraft was engaged in a refuelling mission out of Davis-Monthan and was carrying a crew of 10. While cruising at an assigned altitude of 9,000 feet, the aircraft collided with a USAF Boeing B-50 (46-00047, of the 43rd BG, 63rd BS) that was completing a training sortie from Davis-Monthan with a crew of 13 on board.

Both aircraft went into a dive and crashed in a desert area located in the region of Comobabi, about 50 miles west of Tucson. On board the B-29, six crew members were killed while four others were injured. On board the B-50, seven crew members were killed while six others were injured. The exact circumstances of the collision remains unclear.

NOTE: Some sources (see links #3 & #4) give the crash location as "10 miles North of Nakyama, Arizona". However, no such location had been found. Comobabi is both a census-designated place (CDP) and a populated place in Pima County, Arizona, United States. The population was 8 at the 2010 census. Comobabi is located at 32°03′14″N 111°48′10″W
