A series of widespread UFO sightings across Belgium involving triangular-shaped craft reported by thousands of civilians and tracked intermittently by Belgian Air Force radar and F-16 interception attempts.
Between late 1989 and 1990, Belgium experienced a large wave of UFO reports involving silent, large triangular-shaped objects with bright underside lights. The Belgian Air Force confirmed multiple radar detections and authorized F-16 fighter jet intercept attempts. Pilots reported difficulty maintaining radar lock due to erratic movement patterns and sudden acceleration. The Belgian government later released radar and investigation data acknowledging the events as unexplained.
