The Belgian UFO wave was a series of sightings of triangular UFOs in Belgium, which lasted from 29 November 1989 to April 1990.

The sightings[edit]

The Belgian UFO wave began in November 1989. Reports were filed, most many weeks after the events. Many of the reports related a large object flying at low altitude. Some reports also stated that the craft was of a flat, triangular shape, with lights underneath.[1]

The Belgian UFO wave peaked with the events of the night of 30–31 March 1990. On that night, one unknown object was tracked on radar, and two Belgian Air Force F-16s were sent to investigate, with neither pilot reporting seeing the object. No reports were received from the public on the date. But over the next 2 weeks reports from 143 people who claimed to have witnessed the object were received, all of them after the event. Over the ensuing months, many others claimed to have witnessed these events as well.[2] Following the incident, the Belgian Air Force released a report detailing the events of that night.[citation needed]

At around 23:00 on 30 March, the supervisor for the Control Reporting Center (CRC) at Glons received reports that three unusual lights were seen moving towards Thorembais-Gembloux, which lies to the southeast of Brussels. Glons CRC requested the Wavre gendarmerie send a patrol to confirm the sighting.[citation needed]

Approximately 10 minutes later, some later reports stated that a second set of lights were seen, moving towards the first triangle. Traffic Center Control at Semmerzake tracked one object only on its radar, and an order to scramble two F-16 fighters from Beauvechain Air Base was given. Throughout this time, in reports after the event, some people claim that the phenomenon was visible from the ground, describing the whole formation as maintaining their relative positions while moving slowly across the sky.[citation needed]

Over the next hour, the two scrambled F-16s attempted nine separate interceptions of the targets. On three occasions, they managed to obtain a radar lock for a few seconds, but these were later shown to be Radar-locks on each other. The pilots never reported seeing any of the claimed sightings, saw none of the claimed manoeuvres, and never got a lock on any objects apart from the other F16.[citation needed] The other contacts were all found to be the result of a well-known atmospheric interference called Bragg scattering.

After 00:30, radar contact became much more sporadic and the final confirmed lock took place at 00:40. Following several further unconfirmed contacts, the F-16s eventually returned to base shortly after 01:00.[citation needed]

Members of the Wavre gendarmerie who had been sent to confirm the original report, describe four lights now being arranged in a square formation, all making short jerky movements, before gradually losing their luminosity and disappearing in four separate directions at around 01:30. They also reported that a low engine noise was heard and that it seemed to have a stick coming out one end with a turbine on it, which many have claimed shows it was a helicopter they saw.[3]


A supposed black triangle, 15 June 1990, Wallonia, Belgium. Claimed to have been taken during the UFO wave. A similar photo was taken in Petit-Rechain on 4 April 1990.[4]

Experts say there is no background in the photograph and no element that would allow calculation of the object's size or distance from the camera. Wim van Utrecht has reproduced a copy of the photograph with devices. A computer graphics simulation method[5] to reproduce the photograph was developed by a Belgian mathematician, Thierry Veyt at The University of Liège Laboratory of Astrophysics, wherein the apparent "shake" motion, that results in the lights of the craft appearing blurred or out of focus in the photograph contradicts eye-witness statements. This, along with the anonymity of the photographer and fact that the image was not produced publicly until 4 months after the alleged event, also brought the authenticity of the image into question.
