The late October 1943 Philadelphia Experiment is a tale most people set aside mentally as incomprehensible. Carlos Allende remains mysterious as the 1955 letter writer to Morris K Jessup, author of "The Case For The UFO." The ex-merchant marine, a self-reported witness to the USS Eldridge's disappearance, seemed to warrant the respect of Office of Naval Research (ONR) officers, who reprinted copies of Jessup's annotated book believed sent by Allende. The annotated copies became known as the infamous "Varo Edition". This "official" interest by naval authorities only served to deepen the mystery and interest surrounding Allende.
Robert Goerman, a writer, knew he had the best shot of solving the mystery, since many Allende letters were postmarked from his hometown, New Kensington, PA. Goerman stumbled upon the answer in search of his daughter who liked to visit the cat at the Allen's house down the street. When Goerman made an offhand reference to his research, his neighbor Harry Allen completed his sentence for him and admitted he's Carl's father. Goerman knew he had the right person, when Carl M. Allen's seaman's certificate was found with the number, Z-416175, annotated in many of the letters. The writer ended up with a mystery-solving article for FATE magazine in 1980, "Alias Carlos Allende". The article was not well-received, since the conclusion provided an Allen not an Alien. Goerman's search almost overshadows the rest of the story with much of it retold in this Hidden Mysteries episode, "The True Story Of The Philadelphia Experiment".
