Flying saucers have developed a lot since they were first spotted in 1947. In aftermath of that incident nearly all UFOs seen were saucer shaped. Later, cigar shapes became more common. Although both disc-shaped craft and cylindrical UFOs are still around, the latest batch, seen since the 1980s, are three-sided craft. These Flying Triangles were responsible for the biggest mass sighting in history.
One after the other there were Soviet Encounters, the Belgian wave of sightings, the Mexican wave of sightings, Japan sightings and encounters worldwide. Even Astronauts’ Sightings and Military Encounters were reported.
