Dataset reflects publicly reported events. Durations and passenger counts are taken from the cited primary sources (national civil aviation authorities, ANSPs, and major news organisations such as CNN, Reuters, and Al Jazeera). Authoritative event-level data is published by each national civil aviation authority. As of late September 2025, Danish authorities described the events as a "hybrid attack" but had not publicly identified perpetrators; investigations were ongoing. Methodology is documented at /methodology/.
Operational Pattern Summary
- Concentration of events in late September and October 2025.
- Typical event duration in 2025: 1–4 hours of operational impact, with the majority resolving within a single shift.
- Standard operational response: temporary closure of affected runway(s), diversion of arrivals to alternates, holding of departures on the ground until the airspace is clear.
- Recovery profile: schedules typically returned to normal within 12–24 hours of the event, with knock-on delays propagating through European hub-and-spoke networks for 1–2 days.
- Source-authority response: each event was followed by a national civil aviation authority statement and an investigation referenced in subsequent EUROCONTROL Network Manager publications.

Nordic Drone Incidents 2025 — Frequently Asked Questions
Common search queries answered with current status, FIR codes, and source citations.
- How many drone incidents were reported at Nordic airports in 2025?
- During 2025, multiple drone sightings were reported at major Nordic commercial airports, with the highest concentration in late September and October. The Copenhagen and Oslo events of late September 2025 led to multi-hour closures and diversions. National civil aviation authorities and EUROCONTROL maintain the authoritative incident counts. The dataset on this page summarises publicly reported events; the official tally is published by each national aviation authority.
- Which Nordic airports were most affected?
- The events with the largest published operational impact in 2025 occurred on the evening of 22 September at Copenhagen Kastrup (CPH, EKCH) — approximately a 4-hour flight suspension affecting more than 50 flights and around 20,000 passengers — and Oslo Gardermoen (OSL, ENGM), where airspace was closed for around 3 hours. Aalborg (AAL, EKYT) was closed for several hours during the night of 24–25 September. Smaller events were reported at additional Danish, Finnish, and Swedish airports through Q4 2025.
- Did flights divert or cancel due to the incidents?
- Yes. The Copenhagen event of 22 September 2025 disrupted more than 50 flights according to multiple primary news sources. Affected flights were diverted to nearby airports or delayed on the ground. Specific diversion counts and on-ground holds are published by each airport operator and the relevant national civil aviation authority. Departures were typically held for several hours during active events.
- What FIR codes cover the Nordic airports?
- Denmark — EKDK (Copenhagen FIR). Norway — ENOR (Norway FIR / Bodø area). Sweden — ESAA (Sweden FIR). Finland — EFIN (Finland FIR). Iceland — BIRD (Reykjavik FIR). All are four-letter ICAO designators referenced in NOTAMs and EUROCONTROL publications.
- Where can I find authoritative incident data?
- National civil aviation authorities are the authoritative source: Trafikstyrelsen (Denmark), Luftfartstilsynet (Norway), Transportstyrelsen (Sweden), Traficom (Finland). EUROCONTROL Network Manager publishes regional summaries. Police and airport operators publish event-specific releases. The dataset on this page aggregates publicly available reports; primary sources are listed at the bottom.
