Sighting
Belgian UAP wave begins
Hundreds of witnesses across Belgium, including dozens of national and federal police officers, report large, silent, triangular craft moving at low altitude over the country. The Belgian Air Force scrambles F-16s on 30–31 March 1990 and obtains a brief radar lock that is later attributed to anomalous propagation.
