These are among the most common UFO shapes, according to veteran UFO researcher Brad Steiger, author of Mysteries of Time and Space. The craft has a metallic saucer-like body ranging in diameter from 10 to 15 feet. An exhaust port on the bottom emits a yellow light that dances like a flame upon takeoff.
Bright lights rim the saucer, and a clear cirvular dome is often seen on the saucer portion.
This UFO resembles a Chinese peasant's large straw hat. It has a flat bottom. The craft is generally reported as being about 200 feet in diameter and 10 to 12 feet high at the peak, with no exterior lights. This craft has a thick black body that tapers off at either end. Reports have placed the craft's size at up to 80 feet long and 20 feet high.
