AT A GLANCE

The Belgian Air Force scrambled F-16s to intercept massive black triangles repeatedly observed across Belgium over five months. On March 30, 1990, two F-16s briefly achieved radar lock before the objects performed extreme maneuvers exceeding human G-force limits. The Belgian Air Force released radar data at a press conference — rare official acknowledgment.

DECLASSIFIED DETAILS

Between November 1989 and April 1991, over 13,500 witnesses in Belgium reported low-altitude large black triangular craft with three white lights at the corners and a central red pulsing light. The Belgian Air Force scrambled F-16 fighters multiple times in response to gendarmerie reports. On the night of March 30, 1990, two F-16s from Beauvechain Air Base were vectored to contacts confirmed by NATO and civilian radar. The F-16s achieved radar lock on the objects, at which point the objects descended from 10,000 feet to 500 feet in under a second and accelerated to Mach 1 at ground level — performing maneuvers impossible for any known aircraft. The Belgian Air Force released the F-16 radar tapes at a press conference — one of the most extraordinary official military acknowledgments of UAP pursuit. Major General Wilfried De Brouwer stated the Air Force had no explanation for what the aircraft encountered.

KEY CHARACTERISTICS

  • Mach 1 at ground level — impossible performance
  • Descent from 10,000 ft to 500 ft in under one second
  • Belgian Air Force released radar data officially
  • Major General De Brouwer: 'no explanation found'

Belgian Triangle F-16 Lock-On 1990

Belgium — Wavre area

The Belgian Air Force's most dramatic scramble involved two F-16s achieving radar lock on a triangular craft nine times — each time the craft performed evasive maneuvers reducing its speed from 280 mph to 20 mph in a second. The general of the Belgian Air Force held a public press conference confirming the event.
