Copenhagen closure: drone presence remains unresolved
Current state
Reports prompted an air-traffic closure. A later police update says the Copenhagen investigation could neither establish nor exclude drone activity.

| Claim and source passage | Original source | Assessment |
|---|---|---|
| Reports of drone observations on 22 September 2025 led Naviair to close air traffic at Copenhagen Airport. “Anmeldelserne om droneobservationer den 22. september 2025, som førte til, at Naviair lukkede for lufttrafikken i Københavns Lufthavn” [1] | Danish National Police (Rigspolitiet) | supports: Official statement; the closure itself is established. |
| After the investigation, police could neither prove nor rule out that drones were involved in the Copenhagen and North Jutland cases. “I enkelte efterforskninger har det hverken kunnet påvises eller afvises, at der har været tale om droner. Dette gør sig bl.a. gældende for så vidt angår efterforskningerne i Københavns Politi og Nordjyllands Politi” [1] | Danish National Police (Rigspolitiet) | supports: Outcome of the completed investigation (June 2026); the basis for 'drone presence inconclusive'. |
| Most of the more than 7,000 reports in Denmark were very likely airliners, wind turbine blades or similar, not drones. “observationerne med meget stor sandsynlighed ikke omhandlede droneflyvninger, men hidrørte fra fx rutefly eller vindmøllevinger” [1] | Danish National Police (Rigspolitiet) | context: Context for the wider wave of reports in Denmark in September 2025. |
