How to stop a drone?

Drones are once again in the news, and the recent incident at Copenhagen Airport (Kastrup) in September 2025 underlines the seriousness of the situation. For almost four hours, all air traffic was halted after several large, unknown drones were repeatedly observed in controlled airspace.

Danish authorities characterized the incident as "the most serious attack on Danish critical infrastructure to date" and the operator as a "capable actor". This was not a random hobby drone, but a deliberate act that demonstrated the vulnerability of critical infrastructure.

The incident, which also led to closures at several other Nordic airports and a NATO response, raises a number of technical and strategic questions for engineers and technologists, including: 

  • How can we reliably detect, track, and identify unauthorized drones in a complex environment like an airport?
  • Which countermeasures are both effective and safe to use?

Join the discussion

Participate in a professional conversation with other drone-interested NITO members about how we can best meet these challenges.

Content of the webinar:

  • Introduction: Nils HÃ¥heim-Saers gives an overview of today's technological landscape, what is possible, and what he thinks should be done in the future.

  • Discussion: Open conversation between the participants.

To participate in this event, you must join the Professional Network for Drone Technology, which is free of charge for NITO members. The professional network will have several relevant events related to drone technology in the future. 

Nils Håheim-Saers

Nils Håheim-Saers, overingeniør ved forskningsinstituttet NORCE, har lang erfaring og bred kunnskap om droner og truslene som disse kan utgjøre mot virksomheter og objekter. Hans perspektiver og vurderinger knyttet til dronetrusselen gjør ham til en sann autoritet på sitt felt. Nils var også initiativtaker til Fagnettverk Droneteknologi i NITO våren 2022.
