Drones in Copenhagen and Oslo. Authorities search for perpetrators of airspace violations

In Copenhagen, takeoffs and landings were suspended at around 8:30 p.m. on Monday, with operations resuming shortly after midnight on Tuesday following several hours of airspace monitoring. In Oslo, the first reports of possible sightings appeared late in the evening, with a full closure decision made around 12:30 a.m. and reopening after 3:30 a.m., resulting in an overnight halt to operations and morning consequences for the flight schedule.

Authorities in both countries conducted reconnaissance and security operations in restricted zones around the airports, maintaining the exchange of operational information. They emphasize the preventive nature of their decisions and the use of safety procedures when drone airspace violations are suspected.

In Denmark, media reported 31 diversions and about 20,000 passengers affected by the closure of Kastrup, as well as numerous delays and suspended departures during the evening and night hours. In Norway, after the overnight closure of Gardermoen and morning adjustments to the schedule, at least six flights were canceled and a dozen or so diversions were recorded, with a visible domino effect in the following hours.

Aircraft on approach were directed to alternative airports according to ongoing risk assessments and the availability of air corridors. The wave of delays spilled over to subsequent flights, and the schedule was restored in stages after decisions to resume operations.

In Norway, there were reports of two or three possible sightings near Gardermoen, but in the first hours after the incident, the presence of drones was not definitively confirmed, nor were any operators identified. Police note that verification activities are ongoing. In Denmark, larger drones were reportedly observed for several hours without any suspects being detained, and the investigation is being conducted by the police, security services, and the military.

Danish police did not speculate on motives and indicated there was no evidence that the aim was to cause harm, while maintaining heightened vigilance. Norwegian authorities emphasized that there is no basis to link the incidents in Oslo and Copenhagen, although information channels remain open.
