Modern UFOlogy, at least since its formalization in the early 1950s under the USAF’s Project Bluebook, has been rife with varied reports of unusual aerial objects. The sheer variety of shapes attributed to these UFOs, ranging from the famous “flying saucers” of yesteryear, to the modern reports of massive, looming triangles sneaking through the night skies, do little to help with understanding what such objects may be, let alone their possible sources.
If anything, the UFO mystery has derived more problems from the varieties of the experiences contained within; often, no two reports are alike enough to be able to account for the appearance of mystery that they imply.
Amidst the varieties of UFO descriptions and shapes are, however, varieties that do appear frequently enough that they can fall within categories. The aforementioned flying discs or “saucers” are among the best examples, along with the equally compelling flying triangles that are still often reported. Other varieties include deltoid or chevron-shaped objects, long cigar or torpedo-shaped aircraft, missiles or rockets, spheres, cylinders, and perhaps more often than all the rest, amorphous nighttime illuminations that imply little else but some illuminative energy source.
