Aalborg Airport in Denmark was forced to close its airspace for around one hour overnight on 26 September due to a suspected drone sighting. The shutdown also affected other Danish airports, while similar drone sightings were reported in neighboring Sweden. The information was confirmed by Danish TV channel TV2 and the North Jutland Police.
Drone alert shuts down Danish airspace
Shortly before midnight on 25 September, the North Jutland Police reported the closure of the airspace above Aalborg Airport. A police officer on site observed “something that looked like a drone.“ TV2 reported that more officers were dispatched, and airspace was reopened at 00:35 on 26 September after a full search. Police stated that nothing was ultimately found.
Two incoming flights—from the Faroe Islands and Copenhagen—were rerouted, as shown on Aalborg Airport’s arrival board. According to the airport’s official website, two outbound flights scheduled for 06:20 on 26 September—one to Amsterdam and another to Copenhagen—were canceled. The reason for the cancellations was not officially confirmed as connected to the airspace closure.

Denmark seeks NATO support amid hybrid threats
Danish Defense Minister Troels Lund Poulsen said on 26 September during an interview with Go’ Morgen Danmark that Denmark had reached out to NATO and Nordic allies for support with additional technology and capacity to deal with drone threats.
“Some of the things we’ve experienced this past week, we’ve been too slow — both the military and the police,” Poulsen said, according to TV2. However, he added that the situation was improving.
He called the ongoing drone activity a form of hybrid warfare and said that Danes would need to adjust to the new threat environment.
Sharp rise in drone-related incidents near Danish airports
TV2 reported, citing new figures from the Danish Transport Authority, that drone-related incidents near Danish airports have sharply increased in recent years. So far in 2025, there have been 97 such incidents. In 2024, the number was 92. By comparison, there were 31 incidents in 2023 and 38 in 2022.
The numbers include not only suspected hostile drone flights, but also cases involving hobby drone pilots violating no-fly zones.
