Oslo and Copenhagen Reopen Airports after Drone Activity

On Monday evening, September 22, 2025, Copenhagen Airport was shut down for nearly four hours after two or three drones were spotted flying near the airspace.

The airport halted operations at 8:26 PM local time, diverting around 30 flights to alternate airports. Overall, about 50 flights were affected, causing delays or cancellations and impacting around 20,000 travelers.

Danish police described the drones as operated by a skilled individual with the intent and required equipment to perform the flights that disrupted airport operations.

The drones appeared intermittently from different directions, occasionally flashing their lights before disappearing.

Simultaneously, Norway's Oslo Airport was closed for three hours due to drone sightings. It reopened at around 3 AM local time after diverting flights to nearby airports.

Danish and Norwegian authorities are cooperating to investigate whether there was any connection between the incidents and whether the drones were military or civilian in origin.

No drones had been physically recovered, and the operator remains unidentified.

These events add to a broader pattern of unauthorized drone activity threatening aviation safety.

On September 9, 2025, Russian military drones violated Poland's airspace, prompting temporary closures of four airports: Warsaw Chopin Airport, Warsaw Modlin Airport, Rzeszów–Jasionka Airport, and Lublin Airport.
