Copenhagen Airport Briefly Closed Due to Drone Sightings

Copenhagen Airport experienced a temporary closure on the evening of September 22, 2025, due to the sighting of multiple drones in its airspace. The closure, which commenced around 8:30 p.m. local time, led to the suspension of all takeoffs and landings.

Approximately 15 flights were diverted to other airports as a result of the disruption. Operations at Copenhagen Airport resumed in the early hours of September 23, after being closed for approximately four hours. This incident highlights the increasing concerns regarding drone security and its potential impact on critical infrastructure.

Similar events occurred on the same evening at Oslo Airport in Norway, where airspace was also closed due to drone activity. Authorities in both Denmark and Norway are cooperating to investigate any potential links between these incidents. The drone services market is projected to reach $63.3 billion by 2025, indicating a rapid expansion of drone technology and its associated challenges.

In a significant past event, Gatwick Airport in the UK faced a 36-hour shutdown in December 2018 due to drone activity, which resulted in the cancellation of around 1,000 flights and stranded over 110,000 passengers. This demonstrated the severe economic and operational consequences such disruptions can cause. Regulations regarding drone operation near airports are stringent, typically prohibiting flights within a specific radius of airports, with stricter rules for larger drones. The Federal Aviation Administration (FAA) in the US has recorded over 2,000 drone incursions near airports since 2021, with many incidents prompting pilots to take evasive actions.

The investigation into the drones sighted over Copenhagen Airport is ongoing, with authorities working to identify their origin and purpose. This event serves as a reminder of the need for robust drone detection and mitigation strategies to ensure the continued safety and efficiency of air travel.
