Impact is the average of the four parts, rounded, plus one point when Canada is directly hit on two or more channels, up to 10.

Two separate scales from 1 to 10. Strature never multiplies or merges them.

Why it matters

In late September 2025 reported drones shut Copenhagen Airport for about four hours, then Aalborg and Billund. Copenhagen police said on 25 Jun 2026 that they could not show drones were at Copenhagen Airport. Since then a drone carrying explosives hit an aircraft at Leipzig in August 2026, and Germany blamed Russia; a Russian frigate fired flares at a Danish helicopter on 14 Sep 2026 (Wikipedia summary; low confidence).

Why Likelihood 3 Push: the Leipzig explosive-drone attack, blamed on Russia by Germany on 1 Sep 2026 (official source). The 14 Sep 2026 flares rest on one low source, so they are context, not a driver. Brakes: no Danish closure for 13 months; police could not prove the 2025 drones; drone bans and new powers.

Why Impact 2 Threshold case: one airport stopped for one hour.

  • Billund closed for an hour on 25 Sep 2025 [3] (25 Sep 2025)
  • Copenhagen police cannot demonstrate drone activity at the airport on 22 Sep 2025, nor rule it out [4] (25 Jun 2026)
  • Explosive-carrying drone struck a parked cargo aircraft at Leipzig on 4 Aug 2026; early on 5 Aug a cargo flight hit an unidentified object [5] (5 Aug 2026)
  • Swedish patrol boat jammed a drone launched from a Russian intelligence ship towards Malmö on 26 Feb 2026 [6] (26 Feb 2026)

How it spreads

If

Between 28 Oct 2026 and 27 Oct 2027, a civilian airport in Denmark halts all take-offs and landings for at least one hour because of reported drone activity, as stated by the airport, the air navigation service or the police.

Not under way

Channels 4 on the card

  1. CanadaNo Canadian loss found.
  2. Air travelAn hour's stop at Copenhagen hits about 3,700 passengers on average (Strature's calculation from [8]).
  3. Security policyA new closure would push counter-drone powers and spending [1][2].
  4. RegionSouthern Sweden shares the Øresund airspace [6].

Three scenarios and their signposts

  1. S1

    Quiet skies

    No closure; counter-drone tools and doubts over 2025 calm the response.

  2. S2

    False alarms

    Unconfirmed reports bring short closures.

  3. S3

    Hybrid wave

    A Leipzig-style attack hits a Nordic airport.

The signposts of each scenario
PathSignpost
S1No Danish closure by mid-2027
S2A police statement of a closure under one hour
S3A government naming a state for a drone attack in the Nordics

No probability is given for the three paths.

The other side

Counter-drone sensors, jammers and airport security systems may find more buyers after 2025 [1] (Strature's view). Denmark's experience, including the 2026 finding that early reports were not proven [4], can improve how airports judge alerts (Strature's view).
