Key Findings

• Between September 22 and September 25, 2025, drone sightings near airports in Denmark and Norway resulted in the closure of multiple airports, including two of the major international hubs in Copenhagen and Oslo. While the incidents have not been linked to a suspect or motive to date, the possibility of Russian involvement cannot be ruled out.
• The drone sightings come on the heels of Polish airports being temporarily closed due to Russian drone intrusions on September 10, 2025. They also coincide with a cyberattack that caused disruptions at several major airports in Europe, stirring concerns for the European civil aviation sector.
• The recent airspace violations in Europe—all with a marked proximity to the Russia-Ukraine conflict—very likely signal a rise in drone and other airspace intrusions across northern and eastern Europe.
• In the wake of these disruptions, air carriers are likely to adopt longer routes; proceed with contingency planning, including higher insurance premiums; and experience elevated operational costs for passenger and cargo sectors.
