Mystery drones forced the closure of Oslo and Copenhagen airports on September 22, 2025, disrupting travel for tens of thousands.
Two of Scandinavia's busiest airports, Oslo and Copenhagen, were forced to shut down for several hours overnight into September 23, 2025, due to drone sightings near the airports. This unprecedented closure disrupted the travel of tens of thousands of passengers. Danish police responded to the drone sightings at Copenhagen Airport, leading to suspension of flights. The origin and purpose of the drones remain unknown as investigations continue. The incident raised concerns about airport security and the potential use of drones to disrupt critical infrastructure in the region.
Confidence: High
