Belgian UFO wave (1989–90)

The Belgian UFO wave was a series of reported sightings of large, dark, triangular objects with lights in the skies over Belgium, beginning near Eupen on 29 November 1989 and continuing into the 1990s. The events gained significant attention due to official involvement from the Belgian gendarmerie and Air Force, which famously scrambled two F-16 fighters on the night of 30–31 March 1990 after receiving simultaneous radar and visual reports. While the civilian investigation group SOBEPS concluded the objects were extraterrestrial, and some officials maintained parts of the wave remained unexplained, skeptics attributed the sightings to helicopters, celestial bodies, radar artifacts, and socia

During this wave, 23 different people reported 23 sightings in the area on this site. 14 of the 14 reports that name a shape describe a triangle. 18 include video.
