Belgian UFO Wave, 1989–1991

Record summary

The Belgian wave involved many reports of large, often triangular objects, with substantial attention following a 30–31 March 1990 episode in which Belgian Air Force F-16s were reportedly directed toward radar targets. SOBEPS investigated the reports and published extensive material. The case matters for comparing civilian testimony, radar interpretation, military procedures and media amplification. The nature of the objects remains disputed, and individual reports vary considerably. Some explanations involve misidentification, atmospheric effects or aircraft, while proponents emphasize correlated testimony and radar records.
