The Danish police are seen at Copenhagen Airport, in Kastrup near Copenhagen, on September 22, 2025. Danish police said on September 23, 2025 they did not know who was responsible for flying drones over Copenhagen airport the previous evening, but that they appeared to have been knowledgeable. "The number, size, flight patterns, time over the airport. All this together ... indicates that it is a capable actor. Which capable actor, I do not know," police inspector Jens Jespersen told reporters. The airport was closed for several hours before reopening early Tuesday, causing numerous delays and travel disruptions to 20,000 passengers, airport officials said.

Overview

  • Copenhagen halted take-offs and landings for nearly four hours from about 8:30 p.m. local before reopening around 12:20 a.m., with delays and some cancellations continuing into Tuesday.
  • Flight-tracking data cited by authorities showed around 50 diversions at Copenhagen during the shutdown, with additional cancellations expected as schedules recovered.
  • Danish police said two to three large drones approached from multiple directions, switched lights on and off, then disappeared; no drones were recovered and no arrests were made in Denmark.
  • Oslo restricted operations after separate drone reports and temporarily closed its airspace around midnight, while police arrested two people over a restricted-area drone near Akershus Fortress with no evidence of a link to Copenhagen.
  • Investigators in Denmark and Norway are coordinating inquiries, as the incidents follow a recent cyberattack on European airport check-in and boarding systems supplied by Collins Aerospace.
