Following a supersonic dive and flypast from and during a left bank at about toward the air show's 120,000 spectators, the pilot pulled up into a climb. In less than a second, the aircraft disintegrated: the outer sections of the wing, both engines and the cockpit separated from the airframe. The cockpit, with the two crew members still inside, fell right in front of the spectators nearest the runway, injuring several people. The engines travelled much further on a ballistic trajectory; one engine crashed harmlessly, but the second one ploughed into the so-called Observation Hill, causing most of the fatalities. The rest of the airframe fluttered down and crashed on the opposite side of the runway.
