On the evening of September 22, 2025, two major northern European airports, Copenhagen in Denmark and Oslo in Norway, experienced disruptive drone incursions that forced temporary closures. Copenhagen Airport was shut down for four hours after two or three large drones were sighted nearby; Oslo Airport also closed its runway and airspace for three hours following two drone sightings. Danish police stated the drones were larger than recreational types and likely flown by a skilled operator. Despite investigations involving police, military, and intelligence services, no suspects or drone captures occurred, and the drones disappeared after the incidents. Flight disruptions included cancellation of late flights to German cities and rerouting of 31 flights from Copenhagen. Officials from Denmark and Norway are jointly investigating whether the events are connected. These drone incursions represent hostile airspace violations and pose threats to critical transportation infrastructure in the region.
