F-117 Nighthawk (1981)

Approximately 140 UFO sightings were reported. Hundreds of people saw a majestic triangle craft with a span of approximately 120 feet, powerful beaming spotlights, moving very slowly, without making any significant noise but in several cases accelerating to very high speeds. In short, the Belgian UFO Wave was exceptional and the Air Force could not identify the nature, origin and intentions of the reported phenomena.
