On 6 September 2019 an aircraft almost took off from a taxiway instead of the Zwanenburg Runway. The ISMS partners jointly analysed this incident and a task force was formed to formulate measures to reduce the risks of take-offs from taxiways in the dark. A number of these measures were immediately implemented. For example, the standard night taxi route has been changed and the location has been identified as a hotspot where pilots and air traffic controllers are required to be extra alert. The markings that guide pilots towards the runway have also been made clearer. The task force is working out further structural measures.
