In UFOlogy, the term "wave" means a bunch of sightings over a short period. So, the Belgian wave is a lot of sightings of a triangle shaped UFO over Belgium!
This has got to be the worst intro I've ever done...
Aaanyway, the sightings took place between 1982 and 1983. Over 150 people saw the same triangle shaped craft hovering over their towns and cities. Many people claim this event was a set up by the Belgian government to keep them on the map, but I think otherwise.
It all started in may of 1982 when two Belgian police officers noticed what they thought was an airplane. After chasing it for a few miles, it finally came to a stop. In the air. Where everyone could see it. The police men quickly made a report, and soon enough, hundreds of local Belgians began calling police stations and reporting what they saw.
The strange thing about the sightings was that all the UFOs had 3 shared features.
A triangle shaped body,
Three white lights on each end,
And a bright red light in the middle.
Do you think this was aliens being curious, or planning an invasion? You decide.
