On 13 January 2023, in good night visibility, an augmented crew Boeing 777-200 failed to comply with its departure taxi clearance and with its Captain taxiing crossed a runway in front of a 737 taking off. ATC responded to an automated conflict warning by cancelling the takeoff clearance and a high speed rejected takeoff was initiated from approximately 105 knots with minimum separation as the 777 cleared the edge of the 737 takeoff runway approximately 300 metres. The Investigation concluded that the 777 operator’s risk controls and the airport’s methods for detecting and preventing dangerous runway conflicts were both inadequate.
