Belgian UFO Wave — NATO F-16 Pursuit

The Belgian UFO Wave represents one of the most extensively investigated and officially acknowledged UAP events in European history. Beginning in November 1989 and continuing through April 1991, over 13,500 witnesses filed reports with Belgian authorities describing a large, silent triangular object with bright lights at its corners and a central red pulsing light. On the night of March 30–31, 1990, the Belgian Air Force scrambled two F-16 Fighting Falcons. Both aircraft achieved radar lock on the object on four separate occasions. The radar lock data, released by the Belgian Royal Air Force, shows the object accelerated from 280 mph to 1,100 mph in approximately two seconds — a sustained acceleration of approximately 46G. In a separate measurement, the object descended from 10,000 feet to 1,000 feet in under five seconds. Each time radar lock was achieved, the object executed an evasive maneuver and broke lock within seconds. The Belgian government — uniquely among NATO member states — publicly acknowledged the incidents, released the radar data, and concluded no conventional explanation was found. U.S. Embassy Brussels diplomatic cables, included in the 2026 State Department archive release, document the NATO intelligence sharing implications of the Belgian investigations and note that U.S. defense attaché personnel reviewed the Belgian radar tapes.
