Overview

The Belgian UFO Wave refers to a series of unexplained aerial sightings reported across Belgium between November 1989 and April 1990. It is widely regarded as one of the most extensively documented national UAP waves in modern history due to the large number of witnesses, the involvement of law enforcement and military personnel, and the participation of the Belgian Air Force in the official response.

Over the course of several months, more than 2,000 reports were submitted by members of the public, with approximately 650 cases considered sufficiently detailed for formal analysis. Many witnesses described large, silent, triangular objects displaying bright lights and manoeuvring at low altitude.

The wave reached its most significant point during the night of 30-31 March 1990, when the Belgian Air Force scrambled two F-16 Fighting Falcon aircraft to intercept unidentified radar targets.

The Sightings

The first widely reported sightings occurred on 29 November 1989, when police officers near Eupen, close to the German border, observed a large triangular object with bright white lights at each corner and a flashing red light near its centre.

Over the following months, similar reports were received from civilians, police officers, military personnel and pilots across Belgium.

Witnesses consistently described objects that appeared capable of:

  • Hovering silently for extended periods.
  • Flying at unusually low speeds.
  • Accelerating rapidly.
  • Changing direction abruptly.
  • Operating without visible means of propulsion.

The consistency of descriptions from independent witnesses attracted significant media attention and prompted continued monitoring by Belgian authorities.

Military Response

During the night of 30-31 March 1990, Belgian military radar stations detected unidentified targets corresponding with reports from observers on the ground.

In response, the Belgian Air Force launched two F-16 interceptor aircraft.

According to the official military report, the aircraft obtained several brief radar locks on unidentified targets. Pilots reported that the targets displayed rapid changes in speed, altitude and direction that made sustained tracking difficult.

However, the pilots did not obtain visual confirmation of the objects during the interception.

Military analysts later noted that some radar returns appeared unusual, while also acknowledging that atmospheric conditions and radar anomalies could potentially explain portions of the recorded data.

Investigation

The Belgian Air Force worked closely with the Belgian Society for the Study of Space Phenomena (SOBEPS), a civilian research organisation that compiled witness reports and conducted detailed analyses of the sightings.

The Air Force publicly released portions of its radar data and investigative findings, an unusually transparent approach compared with many earlier military investigations.

Several conventional explanations were considered, including:

  • Misidentification of aircraft.
  • Astronomical objects.
  • Atmospheric conditions.
  • Radar propagation anomalies.
  • Hoaxes in isolated cases.

While some individual sightings were explained, investigators concluded that no single conventional explanation satisfactorily accounted for the entire wave of reports.

The Petit-Rechain Photograph

One of the most famous images associated with the Belgian UFO Wave was the Petit-Rechain photograph, taken in April 1990 and widely circulated as evidence of a triangular craft.

For many years, the photograph was regarded as one of the strongest visual pieces of evidence associated with the wave. However, in 2011, the photographer publicly admitted that the image had been staged using a small model suspended by fishing line.

Although the confession undermined the evidential value of the photograph, it did not affect the large number of independent witness reports or the official military documentation associated with the wider Belgian UFO Wave.

Historical Significance

The Belgian UFO Wave remains one of the most significant national UAP events of the modern era.

Its importance lies in the combination of:

  • Thousands of civilian reports.
  • Multiple police witnesses.
  • Belgian Air Force involvement.
  • Radar tracking.
  • Interceptor aircraft deployment.
  • Public release of official investigative information.

The case is frequently cited in discussions of large-scale UAP waves because of the consistency of witness descriptions and the willingness of Belgian authorities to discuss the investigation publicly.

While no universally accepted explanation has emerged for the entire series of events, the Belgian UFO Wave continues to be regarded as one of the best-documented UAP episodes in European history.
