Historical context
The definitive black-triangle wave: silent, slow platforms with three corner lights, reported by gendarmes, air-traffic controllers, and thousands of citizens. On the night of March 30-31, 1990, Belgian F-16s scrambled and briefly locked radar onto accelerating targets — and the Belgian Air Force, uniquely in history, held a press conference admitting it could not explain the events, cooperating openly with civilian investigators (SOBEPS). The era's icon, the 'Petit-Rechain' triangle photo, was confessed a polystyrene hoax in 2011 — but the sighting mass never depended on it. Coincided with the fall of the Berlin Wall and glasnost-era openness, including the Voronezh circus in the USSR the same autumn.
Skeptical note
Helicopters, an early-AWACS or classified platform, and mass suggestion have all been proposed; the F-16 radar locks were plausibly attributed to atmospheric/electronic artifacts even by SOBEPS physicists. The core visual reports remain unexplained.
