Documented UFO shapes

The array is intended only to convey some idea of the variety of shapes that have appeared, it does not give an adequate impression of the relative frequencies with which the different shapes have appeared. In fact, the images most commonly appearing in my total sample show either a small point, formless blob, or fuzzy ellipse of light in a night sky, or else a dark, more or less distinct ellipse (like that shown in D9) against a lighter sky. With very few exceptions, such as the rocket- or "cigar"-shaped object with "exhaust trail" (G9), which allegedly was photographed over Peru in 1952, the more well-defined objects appear to be some variant of the "Saucer" or "domed disk."
