30km SE Brussels: Triangular UFO Photographed
On March 31, 1990, three witnesses photographed a triangular object overhead 19 miles southeast of Brussels using high-sensitivity film. The UFO's lights appeared dim despite proximity, unlike a control airplane photo, likely due to infrared effects.
Background
Witnesses and Observation
Lucien Clerebaut, secretary-general of the Belgian UFO group SOBEPS, film director Patrick Ferryn, and José Fernandez observed a triangular object passing directly overhead at night on March 31, 1990, about 30 kilometres southeast of Brussels, Belgium. Ferryn estimated the altitude at only 300 metres and its diameter as six times that of the full moon.
Photographic Evidence
They took four photographs on high-speed film. As a control they photographed an ordinary aircraft shortly afterwards in the same part of the sky with identical settings. The UAP's bright lights, which had appeared extremely glaring to the witnesses, were barely discernible on the images. The clear triangular shape, visible to the naked eye, was lost on the film. By contrast, the aircraft's lights appeared on the photographs exactly as bright as they had from the ground, although the UAP had been much closer.
Scientific Explanation
Laboratory tests suggested that this was due to infrared radiation around the object. The event took place in the context of the Belgian UFO wave of 1989–1991 and points to the anomalous photometric properties of the phenomenon. (Source: Eberhart, page 1043; Paris-Match, July 5, 1990)
