Belgian F-16 Intercept
Two Belgian Air Force F-16s were scrambled to intercept multiple radar contacts coinciding with widespread ground reports of triangular craft. Onboard radar locks were briefly achieved but the aircraft did not establish visual contact.

SOBEPS official report ↗Official description
The Belgian Air Force, in coordination with the Belgian UFO study group SOBEPS, published an official summary of the encounter and the broader 1989-1990 'Belgian wave' of triangular-craft sightings. The Belgian government's transparency around the case is itself unusual in UAP history.
Editor's context
One of the few UAP cases with formal NATO-aligned military participation and full official acknowledgment. The radar lock data was made publicly available. Subsequent analyses have proposed atmospheric anomalies and possible classified U.S. stealth aircraft as candidate explanations for portions of the wave; neither fully accounts for the documented radar returns.
In the margins
Transcribed redactions, stamps, and handwritten markings, the paratext of the file. Often the most human part of a declassified document, and worth reading on its own.
