From November 1989 to April 1990, Belgium experienced a wave of triangular UFO sightings witnessed by over 13,500 people, including police officers and military personnel. On March 30, 1990, the Belgian Air Force scrambled two F-16 fighters to intercept an unknown object tracked on radar. The jets reported obtaining radar locks on targets displaying extraordinary capabilities — accelerating from 280 km/h to over 1,800 km/h and dropping altitude from 3,000m to 1,000m in seconds. The Belgian military held an unprecedented press conference acknowledging they could not identify the objects. However, later analysis disputed some radar data, and one famous photo was admitted as a hoax in 2011.
