The Philadelphia Experiment (also referred to as Project Rainbow) was a naval military experiment conducted at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania, USA in 1943. The objective was to render a newly commissioned warship, the USS Eldridge, invisible to radar by means of extremely powerful generators that produced electromagnetic fields to “warp” the radar waves.
When the first tests took place in July 1943, eyewitnesses described the ship almost vanishing in a “greenish fog”. Crew members are alleged to have become embedded in the metal structures of the ship, including one sailor who was transported to a different deck, with his hand embedded in the steel hull. Many apparently complained of severe nausea.
The experiment was repeated on October 28, 1943. This time, according to the more lurid accounts, the Eldridge vanished from the area in a flash of blue light and re-materialised in Norfolk, Virginia, over 200 miles away. It is claimed that the Eldridge remained for some hours in full view of sailors aboard the civilian merchant ship, SS Andrew Furuseth, before vanishing from their sight and reappearing back in Philadelphia. The crew are alleged to have suffered serious side effects. Some are said to have become physically fused to the bulkhead of the ship. Others had died from heart attacks. Those who survived were mentally deranged and had to be admitted to mental asylums. A few appear to have vanished completely.
Widely regarded as a hoax, the Philadelphia Experiment is claimed by conspiracy theorists to be the accidental discovery of time travel. Could the USS Eldridge have slipped through a tear in the space-time continuum, causing its temporary disappearance?
According to the U.S. Navy, the explanation involves the (then) top secret process of degaussing. Degaussing equipment was installed in the hulls of U.S. Navy ships to make them “invisible” to magnetic mines. Another theory is that the ship was indeed used in invisibility experiments, but the generators were used to create heat (rather than magnetic fields) around the ship, creating a mirage effect. This type of invisibility occurs naturally, even making entire islands seem to disappear. The high frequency generators could also account for the sickness of the crew.
Some believe the experiments continued in the form of a series of secret government projects conducted at Camp Hero on Montauk, Long Island…
