Black triangles and boomerangs

Since the 1980s the most frequently reported UFO shape has not been the disc but the triangle and the boomerang. Witnesses speak of huge, matte structures with white or red lights at the corners passing low over houses almost without a sound. Skeptics point to aircraft in formation, airships and secret military craft, but waves of sightings – like the one over Belgium – have never been conclusively explained.
