November 1989 – April 1990

AI impression of the Belgian UFO Wave
AI impression — illustrative, not the original footage or a real photograph.

A period of numerous public reports of large, slow-moving triangular objects over Belgium, during which the Belgian Air Force scrambled two F-16 jets after radar contacts.

What is on the record

The ordinary explanation / open question

A widely published photograph of a triangular craft from the wave was admitted to be a hoax by its creator in 2011, and some of the F-16 radar contacts were later attributed to instrument or propagation anomalies.
