Belgian UFO Wave
In the late 1990s, UFO sightings flooded Belgium. The claims were mainly similar – a low flying strange aircraft with some witnesses describing it as having a black triangle shape with lights on the bottom.
The 1990 UFO wave reached its apex on March 31st when an odd occurrence occurred. The Belgian Air Force sent planes to look for anything unusual after radar detected an unidentified object, but they could not discover anything. During the next two weeks, people reported seeing a strange aircraft – only after it occurred.
