Belgian UFO Wave and F-16 response

OpenOpen / contestedWhere BelgiumWhen 1989–1990

Case

Overview: Civilian and police sightings and Belgian military response; distinguish broad wave from specific 1990 radar event.
Investigative phases: Police reports; military public briefings; radar-intercept narratives
Reported phenomena: Triangular lights; radar contacts
Public evidence status: Secondary accounts and public briefings available; raw military radar data incompletely accessible
Alternative explanations / caveats: Radar lock and visual sightings are not necessarily the same target; some imagery misattributed or hoaxed
Next research tasks: Retrieve original Belgian Air Force briefing and police records; audit radar timelines | V99: Lambrechts report transcription located (SRC-107); no scan or MoD release found online, so the SOBEPS 1991 printing is the next lead.

Why it's still open: Retrieve original Belgian Air Force briefing and police records; audit radar timelines Searched (French, English, Dutch: mil.be, the Belgian State Archives, the Chamber's documents, 'rapport Lambrechts VS 3/Ctl-Met'): no official copy. Patrick Gross's French page (https://ufologie.patrickgross.org/htm/belrap01f.htm) shows 8 low-resolution images of the typed report, with no letterhead, signature or stated provenance; the major's initial reads R, not P. Not searched: the arch.be catalogue, Defence's historical archive, the SOBEPS archive. (chunk G, 2026-11-12) Browser pass (2026-11-12): search.arch.be has been replaced by AGATHA (agatha.arch.be). Its archive-inventory search (about 20,000 inventories of the State Archives): 'UFO' 0 results; 'OVNI' 1, an unrelated family archive (Sammlung Albert Creutz, Eupen). Defence's historical archive and the SOBEPS archive remain unsearched. Flag stays.
