Philadelphia Experiment



The Philadelphia Experiment was an allegedly secret experiment conducted by the U.S. Navy at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania, sometime around the date of October 28th, 1943, in which the U.S. naval destroyer USS Eldridge was rendered invisible to human observers for a brief period of time. It is also refered to as Project Rainbow.

The story is widely regarded as a hoax. The U.S. Navy has stated that the experiment never occurred, and furthermore, details of the story contradict established facts about the Eldridge. It has nonetheless caused a significant ripple effect in many conspiracy theory circles, and elements of the Philadelphia Experiment are featured in many other government conspiracy tales.





Synopsis of the experiment


Several different, at times conflicting, versions of the purported experiment have circulated over the years. The following synopsis serves to illustrate key story points common to the majority of accounts.

The experiment was conducted by a Dr. Franklin Reno (or Rinehart) as a military application of a Unified Field Theory. The theory, briefly, postulates the interrelated nature of the forces that comprise electromagnetic radiation and gravity. Through a special application of the theory, it was thought possible, with specialized equipment and sufficient energy, to bend light around an object in such a way as to render it essentially invisible to observers. The Navy considered this application of the theory to be of obvious military value (especially as the United States was engaged in World War II at the time) and both approved and sponsored the experiment. A navy destroyer escort, the USS Eldridge, was fitted with the required equipment at the naval yards in Philadelphia.

Testing began in summer 1943, and was successful to a limited degree. One test, on July 22, resulted in the Eldridge being rendered almost completely invisible, with some witnesses reporting a “greenish fog” in its place. However, crew members complained of severe nausea afterwards. At that point, the experiment was altered at the request of the Navy, with the new objective being invisibile to radar only.

Equipment was not properly recalibrated to this end, however, but inspite of this, the experiment was performed again on October 28. This time, Eldridge not only became almost entirely invisible to the naked eye, but actually vanished from the area in a flash of blue light. Simultaneously, the US naval base at Norfolk, Virginia, just over 600 km (375 miles) away, reported sighting the Eldridge offshore for several minutes, whereupon the Eldridge vanished from their sight and reappeared in Philadelphia, at the site it had originally occupied in an apparent case of accidental teleportation.

The physiological effects on the crew were profound. Almost all of the crew were violently ill. Some suffered from mental illness as a result of their experience; behavior consistent with schizophrenia is described in other accounts. Still other members were physically unaccounted for— supposedly “vanished”— and five of the crew were allegedly fused to the metal bulkhead or deck of the ship. Still others were said to fade in and out of sight. Horrified by these results, Navy officials immediately cancelled the experiment. All of the surviving crew involved were discharged; in some accounts, brainwashing techniques were employed in an attempt to make the remaining crew members lose their memories concerning the details of their experience.



Origins of the story


The story of the Philadelphia Experiment came to public awareness through a convoluted process; a good overview is provided by historian Mike Dash.


Morris Jessup and Carlos Miguel Allende

In 1955, Morris K. Jessup, an amateur astronomer and former graduate-level researcher, published The Case for the UFO, a book about unidentified flying objects which contained some theorizing about the means of propulsion that flying-saucer-style UFOs might use. Jessup speculated that anti-gravity and/or manipulation of electromagnetism may have been responsible for the observed flight behavior of UFOs. He lamented, both in the book and the publicity tour which followed, that space flight research was concentrated in the area of rocketry, and that little attention was paid to these other theoretical means of flight, which he felt would ultimately be more fruitful.

On January 13, 1955, Jessup received a letter from a man identifying himself as Carlos Allende. In the letter, Allende informed Jessup of the Philadelphia Experiment, alluding to poorly sourced contemporary newspaper articles as proof. Allende also said that he had witnessed the Eldridge disappear and reappear while serving aboard the SS Andrew Furuseth, a nearby merchant marine. Allende further named other crew with which he served aboard the Andrew Furuseth, and claimed to know of the fates of some of the crew members of the Eldridge after the experiment, including one whom he witnessed disappear during a chaotic fight in a bar. Jessup replied to Allende by postcard, asking for further evidence and corroboration for the story.

The reply came months later; however, this time the correspondent identified himself as Carl M Allen. Allen said that he could not provide the details for which Jessup was asking, but implied that he might be able to recall by means of hypnosis. Suspecting that Allende/Allen was a crank, Jessup decided to discontinue the correspondence.


The Office of Naval Research and the Varo annotation

In the spring of 1957, Jessup was contacted by the Office of Naval Research (ONR) in Washington, D.C. and asked to study the contents of a parcel that they had received. Upon arrival, a curious Jessup was astonished to find that a paperback copy of his UFO book had been mailed to ONR in a manila envelope marked "Happy Easter". Further, the book had been extensively annotated by hand in its margins, and an ONR officer asked Jessup if he had any idea as to who had done so.

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 outer 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, Jessup identified "Mr A" as Allende/Allen. Others have suggested that the three annotations are actually from the same person, using three pens.

A transcription of the annotated "Varo edition" is available online, complete with three-color notes.

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. About a hundred 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 follow-up book did not sell well and his publisher rejected several other manuscripts. In 1958 his wife left him, and friends described him as being depressed and 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.



Public dissemination


Resurfacing via literature

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. 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.

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 horrific experiment gone wrong on board the Eldridge in 1943. In 1979, Berlitz and a co-author, William L. Moore, published The Philadelphia Experiment: Project Invisibility, the best known and most cited source of information about the experiment to date.


Hollywood interpretation and the Bielek testimony

In 1984, the story was eventually adapted into a motion picture, The Philadelphia Experiment directed by Stewart Rafill. Though based only loosely on prior accounts of the experiment, it served to bring the core elements of the original story into mainstream scrutiny.

In 1990, Alfred Bielek, a self-claimed former crew-member of the Eldridge and alleged witness of the experiment, supported the version as it was portrayed in the movie, adding embellishments which were disseminated via the internet, eventually to surface in various mainstream outlets. In 2003, Bielek's version of his participation in the Philadelphia Experiment was debunked by a small team of investigators, and the general consensus now is that he was nowhere near the ship at the proposed time of the experiment.





Detractors, skeptics, and other researchers have noted several serious issues and problems with the story of the Philadelphia Experiment.


Evidence and research

Many observers argue it inappropriate to put much credence in an unusual story put forward by one individual, in the absence of more conclusive corroborating evidence. An article written by Robert Goerman for Fate in 1980, claimed that “Carlos Allende”/“Carl Allen” was in fact Carl Meredith Allen of New Kensington, Pennsylvania, who had an established psychiatric history and may have fabricated the primary history of the experiment as a result of his illness.

Dash, in particular, is stark in illustrating the near-total lack of research by those who eventually publicised the story; others speculating that much of the key literature has more emphasis on dramatic embellishment rather than pertinent research. Though Berlitz and Moore's famous account of the story (The Philadelphia Experiment: Project Invisibility) contained much supposedly factual information, such as transcripts of an interview with a scientist involved in the experiment, it has also been criticised for plagiarising key story elements from the fictitious novel Thin Air published a year earlier, which, it is argued, undermines the credibility of the text as a whole.


Scientific aspects

Albert Einstein never fully developed his Unified Field Theory, and no consistent UFT or gravity-electromagnetism link has since come forth from the scientific community. Though Nikola Tesla claimed to have completed a Unified Field Theory shortly before his death in 1943, his theories on electromagnetism's power to distort space and time were never published. Conspiracy theorists propose that much of Tesla's research papers were seized by the FBI promptly following his death, and highlight the apparent coincidence between the year of his death and the supposed date of the Philadelphia Experiment.

More recent research, such as at Duke University demonstrates clearly that, even in 2006, the scientific community was far from attaining the level of technology required to render invisible an object the size of a naval destroyer.


Timeline inconsistencies

The USS Eldridge was not commissioned until August 27, 1943, and remained in port in New York City until September, 1943. The October experiment allegedly 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 . Further evidence against the Philadelphia experiment timeline comes from the USS Eldridge’s complete WWII action report, including the remarks section of the 1943 deck log, available on microfilm


Alternative explanations

Present day scientists propose that the generators rigged to the ship may not have been designed to warp space/time. Instead they may have been deployed to heat up the air and water around the ship, creating an artificial mirage, thereby rendering the ship “invisible” to the human eye. This would still leave visible the ship's wake, in addition to the greenish colored fog described in some accounts.

Alternatively, researcher Jacques Vallee describes a procedure on board the USS Engstrom, which was docked alongside the Eldridge in 1943. The operation involved the generation of a powerful electromagnetic field on board the ship in order to degauss it, with the goal of rendering the ship undetectable — "invisible" — to magnetically-triggered torpedoes and mines. This system was invented by a Canadian, and the British used it widely during the Second World War. British ships of the era often included such systems built-in on the upper decks (the conduits are still visible on the deck of the HMS Belfast in London). Degaussing is still used today; however, it has no effect on visible light or radar. Vallee speculates that accounts of the Engstrom’s degaussing may have been garbled in subsequent retellings, and these accounts may have influenced the story of the Philadelphia Experiment.

A veteran who served on board the Engstrom noted that the Eldridge could indeed have travelled from Philadelphia to Norfolk and back again in a single day at a time when merchant ships could not have — by use of the Chesapeake and Delaware Canal, which at the time was open only to naval vessels. Use of this channel was kept quiet: German submarines had recently been ravaging East Coast shipping during Operation Drumbeat, and thus military ships unable to protect themselves were secretly moved via canals to avoid this threat. It should be noted that this same veteran claims to be the man whom Allende witnessed “disappear” at a bar. He claims that when the fight broke out, friendly barmaids whisked him out the back door of the bar before the police arrived, because he was under age. They then covered for him by claiming that he disappeared.c

In a more speculative and strongly paranormal vein, Al Bielek and Duncan Cameron both claim to have leapt from the deck of the Eldridge while it was in “hyperspace” between Philadelphia and Norfolk, and ended up, after a period of severe disorientation, at the Air Force station Montauk Point, Long Island in 1983, having experienced not only teleportation but time travel. They claim John von Neumann met them there (although officially he died in 1957). This story is part of a continuum involving another alleged secret US Government experiment into the paranormal known as the Montauk Project.
