On 12 October 2013, a Boeing 767-300 commenced take-off at Addis Ababa in accordance with its clearance but rejected take-off at 135 knots when the crew saw an obstruction ahead in the centre of the runway and it stopped approximately 100 metres from a vehicle. The Investigation found that the GND controller had cleared the vehicle to enter the runway, the TWR controller had given take-off clearance without first checking that that the runway was clear. It could not be established whether the GND controller had obtained TWR controller permission to grant the vehicle runway access.
