On 28 June 2024, a Boeing 777-200 was about to get airborne from London Gatwick when the First Officer responded to the pre-set automated ‘V1’ call by retarding the thrust levers instead of moving his left hand to the control column. He then briefly re-advanced them before finally rejecting the takeoff from above V1. The aircraft stopped with about 700 metres of runway remaining and after a brake fire had been extinguished, the passengers were disembarked to buses and the aircraft towed clear. The type-experienced First Officer expressed surprise at his action and could not identify a reason for it.
