On 12 November 2018, an Airbus A320 took off from Macau in good daylight visibility whilst a same-direction runway inspection was in progress but became airborne well before reaching it. The conflict was not recognised until an aural conflict alert was activated, at which point the ATC Assistant took the microphone and instructed the vehicle to clear the runway. The Investigation found that the TWR Controller had forgotten that the vehicle was still on the runway until alerted by the audible alarm and had not checked either the flight progress board or the surface radar before issuing the takeoff clearance.
