On 2 December 2016, the crew of an Airbus A320 passing 100 knots on takeoff at Calgary saw another aircraft crossing an intersection ahead but continued because they considered that, as the other aircraft was already more than half way across, it would be clear before they reached that point. The Investigation found that the GND Controller had cleared the other aircraft to cross after forgetting that the runway was active and under TWR control. It was concluded that the response of the ANSP SMS process to a history of identical controller errors and related reports had been inadequate.
