In late 1955 an anonymous package arrived at the U.S.
Office of Naval Research (ONR). It contained a copy of
Morris K. Jessup's book
The Case for the UFO: Unidentified Flying Objects that was filled with handwritten notes in its margins, written with three different shades of blue ink, appearing to detail a debate among three individuals. They discussed ideas about the propulsion for
flying saucers,
alien races, and express concern that Jessup was too close to discovering their technology. When Jessup was invited to the Office of Naval Research a year later and shown the annotated copy of his book, he noticed the handwriting of the annotations resembled a series of letters he received from Carl Allen, who also signed some of his letters "Carlos Miguel Allende." In the letters to Jessup, Allen put forward a story of dangerous science based on unpublished theories by
Albert Einstein which had been put into practice at the
Philadelphia Naval Shipyard in October 1943. Allen claimed to have witnessed this experiment while serving aboard the . In Allen's account, a destroyer escort was successfully made invisible, but the ship inexplicably teleported to
Norfolk, Virginia for several minutes, and then reappeared in the Philadelphia yard. The ship's crew was supposed to have suffered various side effects, including insanity, intangibility, and being "frozen" in place. When Jessup wrote back requesting more information to corroborate his story Allen said his memory would have to be recovered and referred Jessup to what seems to be a non-existent Philadelphia newspaper article that Allen claimed covered the incident. Twelve years later Allen would say that he authored all the annotations in order “to scare the hell out of Jessup.” The Jessup book with Allen's scribbled commentaries gained a life of its own when the Varo Manufacturing Corporation of Garland, Texas, who did contract work for ONR, began producing
mimeographed copies of the book with Allen's annotations and Allen's letters to Jessup, first a dozen and eventually 127 copies. These copies came to be known as the "Varo edition."{{cite magazine |author-last=Steiger |author-first=Brad |title=The Mysterious Allende Letters |pages=4–9 |magazine=The Allende Letters ==See also==
