Two major Nordic airports shut down overnight due to drone sightings but resumed operations before dawn. The incidents at Copenhagen and Oslo disrupted dozens of flights and triggered investigations in both Denmark and Norway. The drones “disappeared” before they could be recovered, and no drone was identified or captured.
Drone activity shuts down Copenhagen and Oslo airports
Late on 22 September, authorities in Denmark and Norway halted all flight operations at their main airports after drones were spotted in restricted airspace. According to Reuters, Copenhagen Airport suspended all takeoffs and landings from 20:26 local time, citing reports of two or three large drones near its airspace. Around 50 flights were diverted to other airports, FlightRadar reported, according to Suspilne.
Reuters cited Copenhagen Police Deputy Assistant Commissioner Jakob Hansen, who said, “The police have launched an intensive investigation to determine what kind of drones these are. The drones have disappeared and we have not taken any of them.” Hansen added that Danish and Norwegian police would investigate possible links between the two incidents.
Oslo Gardermoen Airport followed with its own shutdown after drone activity was observed overhead, including near the Akershus Fortress, according to Suspilne. Reports of drones first came in around 23:30. At first, traffic was moved to a single runway, but after another drone was spotted, all operations were suspended. The airspace was reopened by 03:22, according to Norway’s Avinor.
VG reported that at least 12–14 flights were diverted from Oslo. Communication chief Monica Fasting at Oslo Airport told VG that six cancellations were reported by early morning and more delays were expected throughout the day. She confirmed to NTB that airspace was shut down for safety reasons.

No drones recovered, investigation ongoing
Oslo police operations leader Gisle Sveen told VG that law enforcement had not been able to confirm the presence of drones within the restricted zone. Another police official, Pål Bjelland, said authorities were collecting reports to determine whether the sightings were actually drones or other flying objects.
Norwegian police said two individuals had been detained for illegal drone activity in Oslo earlier on 22 September. PST, Norway’s security service, is monitoring the situation. In Denmark, PET and the Danish military are also involved in the investigation.
