The First Sightings in November 1989
On the evening of November 29, 1989, approximately 143 witnesses across the Eupen and Liege regions of eastern Belgium reported observing a large, flat, triangular craft moving slowly and silently through the sky. The object was described as having three bright lights at each corner and a pulsating red or orange light in the center. Among the witnesses were two Belgian federal police officers, Heinrich Nicoll and Hubert von Montigny, who tracked the object for over two hours as it moved across the landscape.
The police officers reported that the craft hovered silently at low altitude before accelerating smoothly and disappearing from view. Their detailed reports were filed officially and taken seriously by Belgian authorities. Over the following weeks, hundreds of additional sighting reports poured in from across Belgium, marking the beginning of a UFO wave that would last over a year and generate more than 2,000 documented witness accounts collected by the Belgian Society for the Study of Space Phenomena (SOBEPS).
NATO Radar Tracking and F-16 Pursuit
On the night of March 30-31, 1990, the Belgian Air Force scrambled two F-16 fighter jets to intercept an unknown object that had been detected on multiple radar systems, including NATO installations at Glons and Semmerzake. The radar operators confirmed the presence of an anomalous contact that correlated with visual reports from ground observers and police patrols. This was one of the few occasions in UFO history where a military response was fully coordinated with civilian witnesses and radar confirmation.
The F-16 pilots achieved radar lock on the target multiple times during the pursuit, but the object demonstrated extraordinary performance capabilities each time it was locked. According to the Belgian Air Force's own analysis, the object accelerated from approximately 280 kilometers per hour to over 1,800 kilometers per hour in seconds, dropped from 3,000 meters to 200 meters altitude almost instantaneously, and performed these maneuvers without producing a sonic boom. The pilots were unable to maintain visual or radar contact for sustained periods as the object repeatedly outmaneuvered their aircraft.
Photographic Evidence and Analysis
One of the most widely circulated images associated with the Belgian UFO wave was a photograph taken on April 4, 1990, near the town of Petit-Rechain. The image appeared to show a triangular craft with three lights at its vertices and was considered by many to be compelling evidence. However, in 2011, the photographer Patrick Marechal admitted that the photograph was a hoax created using a painted styrofoam panel, dealing a significant blow to one piece of the evidentiary record.
Despite the Petit-Rechain hoax, the overall case retains substantial credibility due to the volume of radar data and the official military documentation. SOBEPS compiled thousands of witness reports, many accompanied by sketches and diagrams that showed remarkable consistency in describing a triangular or delta-shaped craft. The radar recordings from NATO installations and the F-16 chase remain unexplained and have never been debunked, providing technical evidence that stands independent of any photographic claims.
The Belgian Military's Official Position
The Belgian Air Force took the unprecedented step of holding a public press conference on July 11, 1990, during which Major General Wilfried De Brouwer presented the radar data and admitted that the Air Force could not identify the objects. De Brouwer stated clearly that the detected objects did not correspond to any known aircraft and that the performance characteristics recorded by radar exceeded the capabilities of any technology available at the time. This level of military transparency was virtually unprecedented in UFO history.
General De Brouwer, who later rose to the rank of Major General and Deputy Chief of the Belgian Air Staff, continued to speak publicly about the case after his retirement. He confirmed that the Belgian military had ruled out conventional aircraft, weather phenomena, and electronic interference as explanations. The Belgian UFO wave remains one of the best-documented UFO cases in history, distinguished by the combination of mass civilian witnesses, police observations, multiple radar confirmations, and an honest and transparent military investigation.
