Copenhagen Airport (CPH) has reopened for operations after a four-hour closure due to multiple drone sightings, with flight SK7744 being the first to land, as Oslo Airport also experienced airspace disruptions. The drone activity, which involved fixed-wing drones flying low over CPH, has led authorities to suspect Russian involvement in probing NATO defenses. This follows a period where approximately 50 flights were canceled and 50 diverted. According to social media reports and shared video footage, the drones observed over Copenhagen Airport were described as fixed-wing and flying at low altitudes, leading to speculation that the intent was to be seen and to exploit perceived NATO weaknesses. The Norwegian police have seized a drone in Oslo in connection with drone observations, though a pilot has not yet been located, as stated by operations manager Gisle Sveen of the Eastern Police District. Eurocontrol confirmed that Copenhagen Airport's closure was extended until at least 07:00 UTC on September 23rd, 2025, with an additional 20 flights anticipated to divert. The initial closure began around 8:26 PM local time on September 22nd, 2025, following sightings of multiple large drones that police indicated were not hobby drones. At Oslo Airport, inbound aircraft experienced diversions and holds due to drone observations in the vicinity of the airfield. Previous reports indicated that two foreign nationals were arrested in Oslo on Monday night for illegally operating a drone near Akershus Fortress, a restricted military area. Separately, reports emerged of unusually heavy GPS jamming and spoofing around Kaliningrad, and the Global Sumud Flotilla reported multiple drones following its vessels. Sweden's Defense Minister reiterated the country's readiness to use force to protect its airspace amidst unconfirmed reports of drone activity over Stockholm's Arlanda Airport.
