Petit-Rechain Incident

The Peak Night

On March 30–31, 1990, Belgium experienced the climactic event of a year-long UFO wave that had captivated the nation. Around 23:00 (11 PM), multiple calls flooded the Control Reporting Center at Glons, reporting unusual lights moving silently overhead. An estimated 13,500 ground witnesses observed a massive, flat triangular craft traversing the skies. The object featured three corner-mounted lights with a central red beacon, moved slowly and silently (or with minimal engine noise), and performed maneuvers that seemed to defy conventional aircraft capabilities.

Military Response

Colonel Wilfred De Brouwer, Chief of Operations of the Royal Belgian Air Force, established a Special Task Force Unit to coordinate the response. Two F-16 fighters were scrambled from Beauvechain Air Base to intercept the target. Over one hour, the pilots made nine separate interception attempts but achieved no visual contact with the craft. Radar data showed the object making impossible maneuvers—speed changes from 150 to 970 knots and extreme altitude variations that would be fatal to conventional aircraft occupants. F-16 radar locked onto each other during pursuit but never successfully locked on the target itself.

Two Belgian Air Force radar stations (Traffic Center Control at Semmerzake and Control Reporting Center at Glons) independently tracked the object, providing corroborating data on its trajectory and performance. The radar contacts exhibited flight characteristics inconsistent with known aircraft or known atmospheric phenomena at the time.

Ground Witness Accounts

Wavre gendarmerie (police) officers reported observing four lights in perfect square formation making sharp, jerky movements before the craft disappeared around 01:30 AM. A Belgian police captain reported a giant triangle passing silently overhead. The sheer number and credibility of witnesses—many from law enforcement, military, and civilian professionals—impressed Colonel De Brouwer, who later stated: "What impressed me the most were the witnesses...credible people and they told clearly what they saw."

The incident occurred during a broader wave of sightings that had begun in November 1989. On November 29, 1989, Belgian Gendarmerie officers Heinrich Nicoll and Hubert Von Montigny observed a large triangular craft hovering silently over a field for approximately 30 minutes, tracking its movements before it settled over Lake Gileppe for about an hour—a duration suggesting deliberate, controlled flight.

The Photograph

On April 4, 1990, a photographer identified only as "Patrick" (later identified as Patrick Marechal, then 18 years old) submitted a striking photograph allegedly taken during the wave. The image showed a clear black triangular object with three lights at each corner and a halo of light surrounding the craft. The photograph became iconic, reproduced in UFO literature worldwide as the visual symbol of the Belgian wave.

When researchers overexposed the original image, a triangular shape became visible beneath the lights, and initial expert analysis suggested authenticity with no obvious signs of conventional hoaxing techniques.

The Hoax Dispute

In 2011, over two decades later, Marechal appeared on Belgian television (RTL) and admitted creating the image using a painted styrofoam model with three lights affixed to it, suspended in air for photography. His statement deflated decades of speculation about the photograph's authenticity.

However, the confession itself became controversial. Marechal later alleged that his 2011 admission was fabricated under duress, claiming he was paid money to declare the photo a hoax. He has since refused to provide contact information for his alleged girlfriend who was supposedly present during the photo shoot, and he cannot convincingly recreate the original model or shooting conditions. The dispute over whether the confession is genuine has never been fully resolved.

Investigation & Evidence

The Belgian Society for the Study of Space Phenomena (SOBEPS) conducted an official investigation from 1989 to 1993, producing a comprehensive two-volume report exceeding 1,000 pages. SOBEPS recorded over 2,600 written witness statements and investigated approximately 650 cases. Of those, 500 cases remained unexplained by conventional explanations.

The incident was examined by the French National Space Research Center (CNES), the Belgian Royal Military Academy, NASA scientists, and physicist Dr. Andre Marion. All acknowledged the well-documented nature of the radar and witness data.

Official Explanation

Belgian and NATO authorities later attributed the March 30–31 radar contacts to Bragg scattering, an atmospheric interference phenomenon. However, this explanation did not fully account for the coordinated military and ground witness observations, the F-16 pilot testimony, or the sheer volume of reports from credible observers.
