Keel's thesis that UFOs are part of a long-standing ultraterrestrial deception operation rather than extraterrestrial visitors. Released in 1970, this book is credited to John Keel and is listed here under Illuminet Press. In the Atlas it sits within theory-building and deception studies. It is best read as a scope note on what the work contributes to the larger UAP conversation, whether through argument, testimony, synthesis, or commentary.
