Belgium / 1989 / DISPUTED
Belgian UFO Wave (1989-1990)
The Belgian UFO wave began in November 1989 with reports of large, quiet triangular light formations and later included police observations, radar claims and an F-16 response; the witness record is substantial, but no single technical interpretation resolves the whole wave.

This case is disputed. The archive preserves the claims while separating evidence from interpretation.

Case dossier
The best-known opening reports came from the Eupen area on 29 November 1989. Sightings continued into 1990, and Belgian authorities launched F-16s during a radar-related episode in March. The wave later accumulated photographs and television reconstructions, but one iconic triangle photograph was admitted to be a hoax, so it cannot stand for the wider witness record.
The wave is a key archive case for separating a broad social and witness phenomenon from the narrower technical claims made about particular nights.

Evidence matrix
Evidence assessment
The strongest evidence is the geographic spread of reports, named police witnesses and the existence of military radar discussion. The weakest layer is the visual record: photographs do not securely document one object, radar returns require technical context, and the witness reports vary in distance, duration and detail.
Official context
Belgian military involvement confirms that selected reports were treated as an airspace question. The available official discussion did not identify an extraordinary vehicle, and the radar episode remains debated because tracks, lock quality and visual corroboration do not form a complete public dataset.
Skeptical notes
Aircraft, helicopters, bright stars, formation lights, radar artifacts, expectation and hoaxes can explain portions of the wave. Those explanations should be applied report by report, because the months-long event may combine unrelated stimuli rather than one recurring craft.
