On 11 November 2017, a type-experienced Boeing 747-400ERF crew making a night rolling takeoff at Maastricht-Aachen lost aircraft directional control after an outer engine suddenly failed at low speed and a veer-off onto soft ground adjacent to the runway followed. The Investigation found that rather than immediately reject the takeoff when the engine failed, the crew had attempted to maintain directional control without thrust reduction to the point where an excursion became unavoidable. The effect of startle', the Captain's use of a noise cancelling headset and poor alerting to the engine failure by the First Officer were considered contributory.
