Whether such tales are delusions, fantasies, or hoaxes may be impossible to determine. Some contact cases, however, undoubtedly contain elements of fraud. At worst, the witness may be deliberately inventing the whole story from start to finish; at best, he may feel so certain of the reality of his experience that he feels justified in manufacturing evidence to convince possible skeptics. No matter what his motives, when he tries to add verisimilitude to his narrative by fabricating proofs, he joins the company of hoaxers[X-7]. In the Maury Island case (see _Chapter_ II), the witnesses offered alleged fragments of a disabled spaceship, which turned out to be chunks of slag. The scoutmaster in Florida exhibited singed hair on his arm and a scorched cap to prove that he had suffered from the heat rays of a landed flying saucer (see _Chapter_ VII), and the grain salesman in Nebraska bolstered his tale of the Saturnian ship by pointing to shallow cracks in a dry river bed and oil smudges on the grass (see _Chapter_ IX). A contactee who provided “proof” of his story was Howard Menger, who specialized in describing visits to the moon. In the moon cities, he said, he met many earth scientists who enjoyed a delightful, relaxed existence. The lunar natives use no money, are born without appendixes, and for entertainment play a game very much like baseball. In science they are way ahead of us: using saucers equipped with “self-contained gravity” and propelled by “processed free energy,” they transported him from earth to moon in only two hours[X-8]. As a trophy of his visit, Menger brought back a lunar potato. This remarkable vegetable was supposed to have five times the protein content of an ordinary American potato, but unfortunately it was not available for analysis. As soon as he returned, he said, he had turned it over to the United States Government, and the government was keeping it top secret[X-9]. _Adamski’s Travels_
