The lengthy annotations were written in three different colors of ink, and appeared to detail a correspondence between three individuals, only one of which is given a name: "Jemi". The ONR labeled the other two "Mr. A" and "Mr. B". The annotators refer to each other as Gypsies, and discuss two different types of "people" living in space. Their text contained nonstandard use of capitalization and punctuation, and detailed a lengthy discussion of the merits of various suppositions that Jessup makes throughout his book, with oblique references to the Philadelphia Experiment, in a way that suggested prior or superior knowledge. (For example, "Mr. B" reassures his fellow annotators, who have highlighted a certain theory of Jessup's, "HE HAS NO KNOWLEDGE, HE COULD NOT HAVE. ONLY GUESSING." [sic])
Based on the handwriting style and subject matter, and in comparison to the earlier letters he had received, Jessup identified "Mr. A" as Carlos Allende/Carl Allen. Others have suggested that the three annotations are actually from the same person, using three pens.
Later, the ONR contacted Jessup, claiming that the return address on Allende's letter to Jessup was an abandoned farmhouse. They also informed Jessup that the Varo Corporation, a research firm, was preparing a print copy of the annotated version of The Case for the UFO, complete with both letters he had received. Numbers vary, but it appears that around 100 copies of the Varo Edition were printed and distributed within the Navy. Jessup was also sent three for his own use.
Jessup attempted to make a living writing on the topic, but his followup book did not sell well and his publisher rejected several other manuscripts. In 1958 his wife left him, and friends described him as being somewhat unstable when he travelled to New York. After returning to Florida he was involved in a serious car accident and was slow to recover, apparently increasing his despondency. Morris Jessup committed suicide in 1959.
In 1965, Vincent Gaddis published Invisible Horizons: True Mysteries of the Sea, in which the story of the experiment from the Varo annotation is recounted.
In 1973 Thomas Pynchon published his novel Gravity's Rainbow which is set in World War II and involves both occult and scientific arcana. Many have been puzzled by the title of the work but it is speculated that even though the Philadelphia Experiment is never mentioned in the book the title of the novel comes from the formentioned project also known as "Project Rainbow".
Later, in 1977, Charles Berlitz, an author of several books on paranormal phenomena, included a chapter on the experiment in his book Without a Trace: New Information from the Triangle. (The Philadelphia Experiment did not take place within the so-called Bermuda Triangle).
In 1978, a novel Thin Air by George E. Simpson and Neal R. Burger was released. This was a dramatic fictional account, clearly inspired by the foregoing works, of a conspiracy to cover-up an horrendous experiment gone wrong on board the USS Eldridge in 1943. However, a year later, Berlitz and a co-author, William L. Moore, published The Philadelphia Experiment: Project Invisibility which, though it claims to be fact, as Berlitz's previous books do, plagiarizes Thin Air.
Two movies have been released on the subject: The Philadelphia Experiment (1984) and Philadelphia Experiment II (1993). They are best described as science fiction.
In the computer game Command and Conquer: Red Alert, the Philadelphia Experiment makes a brief appearance — a cutscene shows the Eldridge disappearing, with Einstein informing the player of the "horrible aftermath" the sailors experienced. Einstein later uses the Experiment as the basis for the game's Chronosphere weapon (an Allied teleportation device).
The Experiment has been the subject of several television shows dealing with the paranormal and conspiracy theories, including The Unexplained, a series produced by Bill Kurtis on the cable television network The Arts and Entertainment Network (A&E). A similar story also ran on the show Unsolved Mysteries on the cable tv netork Lifetime.
The 2005 SciFi channel mini-series, the Triangle, explains the strange phenomena in the Bermuda Triangle as the result of the Philadelphia experiment.
Detractors, skeptics, and other researchers have noted several serious issues and problems with the story of the Philadelphia Experiment.
To start with it seems difficult to put any credence in the story at all. The entirety of the story was told by a single person and no corroborating evidence has ever been offered. All of the "research" on the story since Allende's version has consisted primarily of various authors re-telling the story with liberal doses of dramatic embellishment. The best known account, Berlitz's, contains material copied from a science fiction book.
Writer Robert Goerman wrote an article for Fate Magazine in 1980, claiming that "Carlos Allende"/"Carl Allen" was in fact who he claimed to be in later letters, Carl Meredith Allen of New Kensington, Pennsylvania. Allen was a highly intelligent but nonetheless mentally ill itinerant who had likely fabricated the story of the Philadelphia Experiment as a result of his illness. Whether illness or simply a practical joke, it is difficult to consider any of his statements to be real.
The science is even more debatable. Einstein never fully developed his Unified Field Theory (UFT) although he worked on variations of the theme until his death in 1955. A broader understanding of fundamental physics during this period and later has shown that the line of reasoning he was following simply could not work. Unfortunately the name "Unified Field Theory" is used to describe any number of theories that are completely different in nature to Einstein's work, which somewhat confuses the issue. Nevertheless, no consistent UFT or linkage of gravity and electromagnetism has come forth. There is no known mechanism by which an electric or magnetic field of any strength can "bend" or "deflect" light or radar, which are composed of uncharged photons. The idea that the Navy would be able to build an experiment based on a nonexistent theoretical basis is therefore highly suspect.
It could be that the authors in question simply did not understand the science involved and are reporting it incorrectly. Several issues weigh against this interpretation too. The description of the system, which uses gravity to bend light around the ship, is theoretically possible, but would require a mass considerably greater than that of the Sun (which does bend light due to gravity, but only slightly — its mass does not warp space-time all that much).
The historical timeline of the story is equally suspect. The Eldridge was not commissioned until August 27, 1943, and remained in port in New York, until September. The October experiment took place while the ship was on its first shakedown cruise in the Bahamas. A reunion of veterans who served aboard the Eldridge told The Philadelphia Inquirer in April 1999, that the ship had never made port in Philadelphia [2]. (USS Eldridge's complete World War II action report, including the remarks section of the 1943 deck log is available on microfilm, item # NRS-1978-26, from the US Naval Historical Center, Washington Navy Yard, DC 20374-5060.)
The Navy has denied the entire story, of course, but this has only served to convince the conspiracy theorists that it must be true. Various reasons for a coverup are offered, everything from the technology being widely used and still top secret, to the concern that the victims' families would sue for damages.
