Over 13,500 witnesses reported a large triangular object with bright lights traversing Belgium over 18 months. Belgian Air Force F-16s achieved radar lock on the object twice; it accelerated from 280 mph to 1,100 mph in 2 seconds and descended from 10,000 ft to 1,000 ft in 5 seconds. The Belgian government publicly acknowledged and investigated the sightings. U.S. Embassy Brussels diplomatic cables are included in the 2026 archive release.

Calvine UAP — UK Parliamentary Questions and MoD Release

◎Calvine, Perthshire, Scotland, UK

The UK Ministry of Defence held the Calvine photographs SECRET for 32 years. Parliamentary questions in 2021 about the photographs prompted formal government responses. Journalist David Clarke obtained a copy from a former MoD official and published it, which triggered the official National Archives release in 2022. The released DI55 Defence Intelligence Staff assessment showed the MoD concluded the craft was of 'unknown origin' and not any allied nation's program.
