Witnesses Describe UFOs Over Crop Circle Field

The most comprehensive scientific study of an individual crop circle so far--which included x-ray diffraction proof of increased crystallization of clay minerals in a 1999 Edmonton, Alberta (Canada) crop circle-- provides serious evidence that UFOs may be directly involved in the formation of at least some crop circles. Four separate witnesses of UFOs over the Edmonton field just prior to the crop circle's discovery are documented in this "Unsolved Mysteries" segment.
