What was reported

On the evening of 22 September 2025 Copenhagen Airport halted traffic for hours after police reported two or three large drones nearby, and about 35 flights were diverted; in the following days a military air base and other Danish airports suspended operations after similar reports, and the prime minister called them the most serious hybrid attacks on Danish infrastructure so far. After a nine-month investigation the police said in June 2026 they could neither confirm nor rule out drone activity around the airport; no suspect was identified and the case was closed.

Claims and verdicts

Unverified2:07:47 Leslie KeanSecondhand
Regarding 2024-25 mystery drone sightings (New Jersey, the Midwest, Denmark/Scandinavia), none of Kean's insider sources believe they represent alien spacecraft, but they also do not rule out that some UAP could be 'mixed in' with mundane drone activity; the phenomenon remains officially unexplained.
None of the insiders have told me that they believe that they're UAP... but they don't know either. They're not ruling that out.
