originate on another planet and may not even exist as permanent constructions of matter. It is more likely that we see what we want to see and interpret such visions according to our contemporary beliefs. In UFOs: Operation Trojan Horse and The Eighth Tower Keel argues that a non-human or spiritual intelligence source has staged whole events over a long period of time in order to propagate and reinforce certain erroneous belief systems. For example, monsters, ghosts and demons, the fairy faith in Middle Europe, vampire legends, mystery airships in 1897, mystery aeroplanes of the 1930s, mystery helicopters, anomalous creature sightings, poltergeist phenomena, balls of light, and UFOs; Keel conjectured that ultimately all of these anomalies are a cover for the real phenomenon. He used the term "ultraterrestrials" to describe UFO occupants he believed to be non-human entities capable of taking on whatever form they want. In Our Haunted Planet, Keel discussed the seldom-considered possibility that the alien "visitors" to Earth are not visitors at all, but an advanced Earth civilization, which may or may not be human. Interdimensional life is also considered. Keel took no position on the ultimate purpose of the phenomenon other than that the UFO intelligence seems to have a long-standing interest in interacting with the human race. The Mothman Prophecies His 1975 book The Mothman Prophecies was Keel's account of his investigation into alleged sightings in and around Point Pleasant, West Virginia of a huge, winged creature called "Mothman." The book combines Keel's account of receiving strange phone calls with reports of mutilated pets and culminates with the December 15, 1967, collapse of the Silver Bridge across the Ohio River. The book was widely popularized as the basis of a 2002 film of the same name starring Richard Gere, Will Patton, Laura Linney and Alan Bates. Gere and Bates played two parts of Keel's personality. Bates's character is named "Leek," which is "Keel" spelled backwards; Gere's newspaper journalist character is named "John Klein," also a play on Keel's name. In the May/June 2002 issue of Skeptical Inquirer, journalist John C. Sherwood, a former business associate of UFO researcher Gray Barker, published an analysis of private letters between Keel and Barker during the period of Keel's investigation. In the article, "Gray Barker's Book of Bunk," Sherwood reported finding significant differences between what Keel wrote at the time of his investigation and what he wrote in his
