Belgian UFO Wave
A wave of triangular UFO sightings over Belgium from 1989 to 1991, tracked by military radar and investigated by the Belgian Air Force with support from NATO.
OVERVIEW
Between November 1989 and April 1990, Belgium experienced one of the most well-documented UFO waves in history. Hundreds of witnesses reported a large black triangular craft with bright lights at each corner. On the night of March 30-31, 1990, the Belgian Air Force scrambled F-16 fighters to intercept unknown objects. Radar data showed objects accelerating from 1,000 to 11,000 km/h and dropping thousands of feet in seconds — maneuvers impossible for known aircraft. The Belgian military officially acknowledged the event and released a comprehensive report.
KNOWN FACTS
Belgian Air Force radar data documenting objects with no conventional flight characteristics
F-16 radar lock logs showing instantaneous acceleration from subsonic to hypersonic speeds
Hundreds of independent witness statements from across Belgium describing identical triangular craft
Official Belgian Air Force public briefing and report acknowledging the events
Photographic evidence including the famous Petit-Rechain photograph (still debated)
CLAIMS
A large triangular craft of unknown origin flew over Belgium for months
Belgian F-16 fighters achieved radar locks on objects performing impossible maneuvers
NATO radar systems also tracked the objects
The Belgian Air Force issued an official report acknowledging the unexplained nature of the sightings
The same triangular craft was reported across Europe during the same period
EVIDENCE FOR
Belgian Air Force radar data documenting objects with no conventional flight characteristics
F-16 radar lock logs showing instantaneous acceleration from subsonic to hypersonic speeds
Hundreds of independent witness statements from across Belgium describing identical triangular craft

EVIDENCE AGAINST
The Petit-Rechain photograph was later claimed by a hoaxer, though the claim remains disputed
Some suggest temperature inversions or atmospheric phenomena could explain radar anomalies
The sightings coincided with heightened public interest, potentially amplifying reporting
NATO has not officially released its own radar data from that night
Some witnesses may have misidentified military helicopters or aircraft
