The Philadelphia Experiment is an alleged military experiment supposed to have been carried out by the US NAVY. at the PHILADELPHIA NAVAL Shipyard.
 in PHILADELPHIA, Pennsylvania, sometime around October 28, 1943. The U.S. Navy  was claimed to have been rendered invisible (or "cloaked") to enemy devices.
The story first appeared in 1955, in letters of unknown origin sent to a writer and astronomer,Morris K Jessup. It is widely understood to be a Hoax, the U.S. Navy maintains that no such experiment was ever conducted, that the details of the story contradict well-established facts about USS Eldridge, and that the alleged claims do not conform to known physics laws.

Misunderstanding of documented naval experiments

Edit

Personnel at the Fourth Naval District have suggested that the alleged event was a misunderstanding of routine research during World War II at the Philadelphia Naval Shipyard. An earlier theory was that "the foundation for the apocryphal stories arose from degaussingexperiments which have the effect of making a ship undetectable or 'invisible' to magnetic mines." Another possible origin of the stories about Levitation, Teleportation and effects on human crew might be attributed to experiments with the generating plant of the destroyer USSTimmerman (DD-228), whereby a higher-frequency generator produced Corona discharges, although none of the crew reported suffering effects from the experiment.
Observers have argued that it is inappropriate to grant credence to an unusual story promoted by one individual, in the absence of corroborating evidence. Robert Goerman wrote in Fate magazine in 1980, that "Carlos Allende" / "Carl Allen", who is said to have corresponded with Jessup, was Carl Meredith Allen of New Kensington, Pennsylvania, who had an established history of psychiatric illens and who may have fabricated the primary history of the experiment as a result of his mental illness. Goerman later realized that Allen was a family friend and "a creative and imaginative loner ... sending bizarre writings and claims."
