Belgian UFO Wave (1989-1990)

The Belgian UFO Wave stands as one of history's most credible UFO events, involving over 2,000 documented sightings. The phenomenon peaked on March 30, 1990, when multiple police units tracked a massive triangular craft moving silently at low altitude. NATO radar confirmed an unidentified object matching visual reports. Unlike typical cases, these sightings involved trained observers including police and military personnel, with consistent descriptions of a black triangle with bright lights. Despite official investigations, no conventional explanation was found, leaving this as one of Europe's best-documented unsolved UFO cases.
