At 120 knots, the flight crew noted the onset of a vibration. When the vibration increased, the captain elected to reject and assumed control. Four to eight seconds elapsed between the point where the vibration was first noted and when the RTO was initiated (just after V1). Subsequent investigation showed two tires had failed. The maximum speed reached was 158 knots. The airplane overran the end of the runway at a speed of 35 knots and finally stopped with the nose in a swamp. The airplane was destroyed.
At 154 knots, four knots after V1, the copilot’s side window opened, and the takeoff was rejected. The aircraft overran, hitting a blast fence, tearing open the left wing and catching fire.
According to an FAA study of high speed rto accidents (120kt and above) 18% were unavoidable and 52% would not have occurred if the takeoff was continued.
Not excusing the systemic stuff up that led to this but strongly cautioning the idea of v1 + rejects. It may work out ok sometimes (45%) but the when it doesn't people can die.
