The Belgian UFO Wave (1989–1990): Triangular sightings, radar corroboration, and an unresolved mystery

To the point

From late 1989 to early 1990 there were many reports in Belgium of triangular UFOs with bright perimeter lights and a flashing center light, police and radar noted unusual activity, two F-16s were scrambled but no firm visual confirmation, the SOBEPS investigation found the events could not be explained by normal aircraft or natural phenomena, a photo claimed by Patrick Maréchal was later admitted as a hoax, and a range of explanations—extraterrestrial visitors, advanced military tech, atmospheric effects, mass hysteria or misidentifications—were debated, with skeptics questioning the radar and evidence, making it one of the most studied and unresolved chapters in UFO history.
