Introduction
On the evening of September 22, 2025, Denmark’s Copenhagen Airport—one of Europe’s busiest air travel hubs—was abruptly closed after two to three large drones were spotted near the airspace, triggering an unprecedented wave of flight diversions throughout Scandinavia and Northern Europe. The closure caused chaos for more than 20,000 travelers, diverting over 35 flights to alternative airports including Billund, Aarhus, Malmo, and Gothenburg. This incident is now being described by Denmark’s Prime Minister as “the most serious attack on Danish critical infrastructure to date” and is prompting urgent questions about drone security, airport resilience, and traveler safety in the digital age.

Copenhagen Airport Shutdown: What Happened?
Around 8:30 p.m. local time on September 22, 2025, Danish police halted all take-offs and landings at Copenhagen Airport after reports of 2-3 large unidentified drones in the airspace. Oslo Airport in Norway also shut down all air traffic due to a similar incident the same night.
Police confirmed the drones were operated by a “capable actor,” turning their lights on and off and approaching from several directions before disappearing. The authorities refrained from shooting down the drones due to safety concerns, given the close proximity of planes, passengers, and fuel depots.
- All inbound flights to Copenhagen were diverted, often at short notice, to Billund, Aarhus, Malmo (Sweden), and Gothenburg airports.
- Travelers in terminals and on planes faced hours of anxiety, waiting for updates with little information available.
The Impact: Diversions, Delays & the Human Story
The closures had ripple effects across Scandinavian and Northern European air corridors:
- Copenhagen Airport, serving almost 30 million passengers annually, was closed for nearly four hours, delaying, canceling, or diverting flights for over 20,000 travelers.
- Over 35 flights were confirmed diverted by tracking services; some sources suggest up to 51 flights were impacted.
- Oslo Airport faced similar chaos, with flights rerouted to the nearest available runways and alternative airports.
Passenger Experience
Travelers described confusion, anxiety, and frustration:
- Many were stranded on planes or in terminals with limited information.
- Delays cascaded into the following day, impacting business, holidays, and onward connections.
- Airports issued repeated advisories, urging passengers to check with airlines.
Drone Threats & European Security—A Growing Risk
Prime Minister Mette Frederiksen labeled the incident the “most serious attack” on Denmark’s vital infrastructure yet. She cited broader concerns:
- Recent surge in drone disruptions, including Russian drones breaching NATO airspace.
- Pattern of “drone attacks, airspace violations, and cyberattacks” at major European airports.
- NATO and EU aviation authorities are on high alert after similar breaches in Romania, Poland, and Estonia.
The incident fits a troubling trend where new digital threats (drones, hacking) can cripple critical infrastructure and complicate traveler security in Europe.
How Airports & Authorities Responded
Danish and Norwegian police, along with military units, responded rapidly:
- Large police and emergency presence was mobilized in and around both airports.
- Military units were on standby, prepared for escalation, but shooting down drones was determined too risky near crowded airport facilities.
- Authorities conducted a forensic investigation using radar, cameras, and witness statements but have yet to identify suspects or the origin of the drones.
Norwegian police arrested two foreign nationals for flying drones near a military site—though the incidents are not confirmed to be connected, prompting wider speculation about motive and responsibility.
What Does This Mean for Future Air Travel?
Security Upgrades and Traveler Preparedness
- European airports will likely accelerate investments in drone defense and surveillance technology.
- Governments and aviation regulators are now urged to develop new laws and countermeasures for unauthorized drone activity near airports.
- The episode shines a spotlight on traveler resilience: being prepared for sudden disruptions and knowing how to quickly rebook or reroute can make or break travel plans.
