The Philadelphia Experiment From A-Z

Carlos Miguel Allende or Carl Meredith Allen or..

The whole story of the Philadelphia Experiment stems from Carl M. Allen’s letters to astronomer, researcher, and writer Morris K. Jessup. Carl provided most of the “facts” that are still used in books today, for example; The name of the test ship, the location and date of the experiment, etc. With most of the “facts” coming from one individual (and later being “confirmed” by others) one begins to wonder who is Carl Allen, and is he of sound mind.

Carl Allen, or Allende (pronounced Aye-enday) was born on May 31, 1925 in the small Pennsylvania town of Springdale. Carl was the youngest of four childern, three brothers Donald, Frank, and Randolph, and one sister Sarah. His father Harold Allen, was Irish and his mother was part French. He quit school in at the age of nine, and on July 14, 1942 he joined the Marine Corps, and was later discharged on May 21, 1943. Carl enlisted in the Merchant Marine in July 1943, and served on the S. S. Andrew Furuseth from August 16, 1943 till late January, 1944. Allen served on 27 different ships in total before he left the service in October, 1952. [1]

Carl has been described in many books and texts as a wandering “Gypsy.” (also Carl’s mother was referred to as a Gypsy.) Although his lifestyle may conform to the ideals of a Gypsy, he has no real Gypsy heritage in his family.

“There is something in October sets the gypsy blood astir.” [2]

While at one of Mr. Jessup’s lectures, Carl Allen heard Jessup impress upon his audience the urgent need for some type of Government-sponsored research program in a basic study of gravity, beginning with continued research into Dr. Albert Einstein’s Unified Field concepts. When Allen heard this he felt he had to write to Mr. Jessup (the first letter arrived on January 13th, 1956), describing that such research was already “horribly” complete. He described in detail a Naval experiment involving optical invisibility and teleportation. Carl Allen provided much more information than the typical model of a “hoaxer.”

Carl left his Sailor’s ID number (Z416175) at the bottom of one of his letters to Mr. Jessup. After a check of this ID, Carl’s “Certificate of Seaman’s Service” was found. It had been signed by William B. Durham, Commander, USCG (United States Coast Guard), Chief, Merchant Vessel Personnel, Records and Welfare Division. This certificate confirmed that Carl was a sailor and had served on the S. S. Andrew Furuseth in 1943 (within the same time frame as the alleged experiment.)

Not long after Allen’s correspondence with Jessup, some interest in the matter was shown by a few Naval officers, who wanted to know more and decided to seek out this “Carlos Allende” and perhaps inquire more details from him of the secret ship experiment he had evidently witnessed. The reason for the Naval officers’ involvement was that a copy of Morris Jessup’s book The Case for the UFO had been mailed anonymously to one of the officers. The book had been heavily hand-annotated in the margins, throughout the book, in three different inks and styles; the marginal notes were evidently supposed to be a running commentary by three individuals who seemed to display extraordinary knowledge of things scientific, cosmic, and esoteric. In brief, one got the impression that some of the writers were “not of this world” but from a superior, extraterrestrial race. What concerned the Navy men most was that mention was made of a strange and secret experiment that was supposed to have taken place aboard ship in 1943. The experiment got out of control, it was said, and was disastrous for the crewmen on board. Magnetic force fields had been employed and more than just radar invisibility had occurred. The Navy men were intrigued. Could there be any truth to this? They decided to find Allende and see. [3]

All attempts by the Navy to locate Carlos Allende in 1956,  failed. [4] In the 1960’s several “fake” Allendes turned up offering to sell the whole story if the price was right. By this time the story had spread into the “fringe science” and “ufology” groups; the sudden appearance of all the fake Allendes caused some to doubt if there even was a real person named Carlos Allende. As the years passed Allen became bitter at the unwanted publicity of his letters, and the simple fact that everyone but him was profiting from his story. In 1969, to “get back at them all,” he handed Jim Lorenzen of A.P.R.O. (Aerial Phenomenon Research Organization) a copy of the Varo Edition (of Morris Jessup’s book, The Case for the UFO) with the following “confession” attached to the second page of the Appendix:

“All words, phrases, and sentences underlined on the following pages in brown ink are false. The below page and the top part of the following [5] were and are the craziest pack of lies I ever wrote. Object? To encourage ONR Research and to discourage Professor Morris K. Jessup from going further with investigations possibly leading to actual research. Then I feared invisibility and force-field research; I don’t now.” [6]

“Allende still believes… that a U.S. vessel… disappeared from its Philadelphia dock and reappeared seconds later in the Norfolk-Portsmouth area, then disappeared again to appear once more in its original berth.” – Jim Lorenzen of A.P.R.O.

Carl Allen described his experience from the foredeck of the S.S. Furuseth where he was standing watch. He states that the disappearance of the DE-173 occurred between 17:05 and 17:20 hours on, the 27th or, more likely, the 28th or 29th of October 1943. Allen watched the gradual disappearance of the destroyer escort (just a short distance away and nearly alongside the Furuseth); his narration is as follows:

In 1946 the Furuseth was sold to Norway after the war, and was renamed the Essi and served in the Norwegian Merchant Fleet

S.S. Andrew Furuseth

“What occurred next? What did I observe next? I looked at the thin air where once had lain, and I could see, from the hull impression [in the ocean], the impression of the weight of the entire ship upon its bottom hull — that this impression, this weight, was causing an impression to be pushed, still, yet, down into the water as the DE sailed along, quite invisible, not visible to the human eye – I repeat, human eye — but there it sailed along making that impression, and that was the only evidence there was a solid, heavy, ship-shaped object of, at least, extreme transparency if not absolutely and totally invisible laying in that water propelling itself along at a normal speed, and then it scooted off and resumed patrol” – Carl Allen [7]

In 1980 Robert A. Goerman did some research into the PX for an article he was writing for FATE magazine.  Goerman’s conclusion after talking to Harold Allen (Carl’s father) and looking over some family documents were that:

“Carlos loves to play games with those foolish enough to play audience…” In a letter to his parents, Carl admits annotating Jessup’s book, by himself.[8]

In 1983 Carl Allen turned up in Boulder, Colorado. He also wrote to Jacques Vallee between 1967 and 1968. Allen offered to sell his acquired information, including a special copy of the Varo Edition (which he has since entered more notes into) for the “reduced” sum of $1,950.

Here are some of his statements to Dr. Vallee; the first letter arrived in October 1967 from Monterrey, Mexico, the second is postmarked Minneapolis:

“After this tremendous explosion my hair came out in bunches in my comb and I observed same result in other Deck-crew members…” [9]

The above statement is interesting, and certainly resembles the effects of poisoning by nuclear radiation. Yet we have no evidence that Allen was ever exposed to any dose of radiation massive enough to cause his hair to fall out (he certainly seems to have grown it back to a normal pattern for an older man by the time photographs of him began to appear in the late 1980’s), nor has anyone said he needed prolonged treatment, such as chemotherapy, for any later development of cancer. etc. With This we began to wonder if the Philadelphia Experiment was a cover-up for some sort of nuclear incident in the Philadelphia Naval yard. What follows is an interview with a elderly scientist; we will refer to him as Dr. Frank Syan.

A.H.    “I have been doing some research into the Philadelphia experiment that has been written up in many books…”

F.S.    “which one”

A.H.    “The story of a ship.. the U.S.S. Eldridge being rendered invisible to the eye or radar..”

F.S.     “yeah.. yeah.. I think I have heard about it.”

A.H.    “You were interviewed about the Manhattan Project?”

F.S.     “Well yeah…”

A.H.    “When talking to another individual about Roswell, the subject of the Philadelphia Experiment of 1943 came up. At that point he could not remember exactly what you said in regards to the Experiment and possibly an accident… So I was just wondering if something might have happened back then that the government might have tried to cover up to some degree… disinformation…”

F.S.      “There was an accident in Philadelphia in 1944, but not 43. In September of 1944 there was an explosion at a pilot plant.. and uh.. two people were killed and several injured… and because of security at that time I think it was covered up.”

So what we learned is that there was a “accident” late in 1944 but not 1943. {Not to be ruled out is the distinct possibility (some would say “probability”) that the PX story as it has come down to us is a carefully crafted piece of disinformation, orchestrated via psychological warfare techniques by whatever military/government agency has seen fit to promote it, either as a cover-up for something that happened at Philadelphia during WW2 or for other, more obscure reasons.} To continue to quote Carl Allen:

“I Watched it, saw it, observed its birth, growth, action and reaction upon the vehicle to which the super-field was being applied; I smelled it… my mouth tasted the ozone odor of it and my ears heard the sizzing-hum of its surrounding electrical envelope.” – Carl Allen[10]

The following is a part of Carl Allen’s statement to Bill Moore:

Carl Allen aka Carlos Miguel Allende, 1977 (from the Gray Barker Collection, Clarksburg-Harrison Public Library)

Carl Allen aka Carlos Miguel Allende, 1977

“I actually shoved my hand, up to the elbow, into this unique force field as that field flowed, surging powerfully in a counter clockwise direction around the little experimental Navy ship, the DE 173. I felt the…push of that force field against the solidness of my arm and hand outstretched into its humming-pushing-propelling flow.

I watched the air all around the ship… turn slightly, ever so slightly, darker than all the other air… I saw, after a few minutes, a foggy green mist arise like a thin cloud. this must have been a mist of atomic particles. I watched as thereafter the DE 173 became rapidly invisible to human eyes.

…in trying to describe the sounds that force field made as it circled around the DE 173… it began as a humming sound, quickly built up… to a humming whispering sound, and then increased to a strongly sizzling buzz —rushing  torrent…

The field had a sheet of pure electricity around it as it flowed. …flow was strong enough to almost knock me completely off balance and had my entire body been within that field, the flow would of a most absolute certainty knocked me flat… on my own ship’s deck. As it was, my entire body was not within that force field when it reached maximum strength- density… I was not knocked down but my arm and hand only pushed backward with the field’s flow.

…Naval ONR scientists today do not yet understand what took place that day. They say the field was ‘reversed’. Scientific history, I later came to realize, was made for the first time that day.” – Carl Allen [11]

In the first letter Carl Allen wrote to Mr. Jessup:

“The “result” was complete invisibility of a ship, Destroyer type, and all its crew, While at Sea (Oct. 1943) The Field Was effective in an oblate spheroidal shape, extending one hundred yards (More or Less, due to Lunar position & Latitude) out from each beam of the ship.” – Carl Allen [12]

While Carl Allen was still alive I tried to locate him. My first lead on Carls whereabouts was a letter he had written from a VA Hospital, in Greely. Unfortunately Greely does not have a real VA Hospital, but a 30 VA Temporary shelter. I checked with other care-homes in the Greely area, and found the most probable one “The Villa,” unfortunately the most helpful attendant that had been working there for some time, did not remember the name. He searched the records, and no match was found. My experiences while performing research on Carl revealed a somewhat depressing reality. All stories I received were of the same flavour. Bob Warth of Pursuit magazine talked at length with me, in regards to one of his meetings with Carl.

Carl showed up at our doorstep (on July 16th, 1977) with thirteen pieces of luggage, and the intention of staying a while… I interviewed Carl in the blazing heat, we were both dripping, for about two hrs……{This is not Done!}” – Bob Warth [13]
