The crew left Travis AFB on a special mission consisting of an aerial attack of the city of Portland. Two pilots on board a Lockheed F-94 Starfire registered 49-2574 left McChord AFB to assist the bomber in this mission. In flight, while engaged in a gunnery mission, both aircraft collided. It is believed that during one of the mock passes at the bomber, the fighter struck the outer wing of the B-29. While the crew of the Starfire was able to complete an emergency landing at Aurora Airport, the heavy bomber went out of control, dove into the ground and crashed in a field. All 11 crew members were killed.

While flying at a height of some 5,000 feet, the left wing hit a peak and was sheared off. The aircraft crashed and burst into flames on the slope of Mt Richter, at the altitude of 4,200 feet.

When the crew started the approach to McChord AFB, he was informed that a landing was not possible due to poor weather conditions. The captain decided to return to Fresno but while flying east of Coos Bay, the crew decided to bail out and abandoned the aircraft that crashed in a wooded area located 42 miles east of Coos Bay. Rescuers arrived on site two days later and nine occupants were evacuated. For unknown reason, two people were still in the aircraft and were killed while a third one was never found. The exact cause and circumstances of the accident remains unknown.

Enroute, the seaplane hit the slope of a mountain near Brookings, killing all nine crew members.

The airplane departed Boise-Gowen Field on a liaison flight to Pendleton, Oregon. While cruising at night in marginal weather conditions, the airplane deviated from the prescribed route and impacted the slope of a mountain located in the Blue Mountain Range, some 20 miles southeast of the destination airport.
