9. Belgian Triangles, 1989
It became obvious fairly quickly that triangle-shaped UFOs were not exclusive to the United States. Similar to the Hudson Valley Sightings, the sightings in Belgium featured multiple reports of triangle-shaped craft operating silently in the skies. Reports were even made by police, and at least one sighting prompted the military to launch two U.S.-made F-16 Fighter jets in an attempt to intercept the craft. The objects were also confirmed by radar operators and were captured on film by some alert residents during April of 1990.
