After takeoff from Yokota AFB, while climbing to a height of 150 feet, the engine number four caught fire. The airplane continued to climb to 500 feet when the engine number two caught fire as well. At a height of 600 feet, two explosions occurred in the engine number two and at a height of 650 feet, nine crew members bailed out. The airplane stalled and crashed in flames about 10 km from the airbase. Three crew members were killed while all crew who bailed out were rescued.

Following technical modifications, the crew was engaged in a local test flight out from San Diego Airport. In flight, the engine number five caught fire. The pilot-in-command instructed his crew to bail out and elected to steer the aircraft away from the populated area. Eventually, the airplane went out of control and crashed into the sea about 3,5 miles off San Diego. The pilot and a second crew member were killed while six others were found alive.
