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.
