The Facts on UFO’s and other Supernatural Phenomena (Harvest House, 1992), pp. 7-8
What are UFOs?
The UFO phenomenon encompasses a wide range of phenomena and experiences. For purposes of simplification in describing these phenomena, we will use a broad classification incorporating the following seven categories:
• Distant Sightings (DS) involve observations of anomalous lights in the sky, nocturnal discs, etc., visually or on radar.
• Close Encounters of the First Kind (CEI) constitute sighting a UFO, with or without occupants, at 500 feet or closer.
• Close Encounters of the Second Kind (CEII) involve UFOs that leave physical effects on the environment such as landing marks, broken tree limbs, etc.
• Close Encounters of the Third Kind (CEIII) comprise the sighting of UFOs with occupants, at very close range, including landed craft with occupants in or about the craft.
• Close Encounters of the Fourth Kind (CEIV) involve alleged abductions by UFOs, where people claim to be involuntarily taken on board a UFO for experimentation, purposes of communication, or other reasons. Such episodes are characteristically “forgotten” until a strange series of events leads to “uncovering” the “abduction” under hypnosis.
• Close Encounters of the Fifth Kind (CEV) involve what are termed “contactees,” those persons who claim to be in personal contact with UFO entities, typically through occult means.
• Close Encounters of the Sixth Kind (CEVI) include injuries or deaths resulting from a UFO close encounter.
