On August 12, 1943 (or October 28, 1943 - accounts differ) the US Navy conducted a test of some sort on the USS Eldridge (DE [Destroyer Escort] 173) at the Philadelphia Navy Yard. The exact nature of this test is open to speculation. Possible tests include experiments in magnetic invisibility, radar invisibility, optical invisibility or degaussing (rendering the ship immune to magnetic mines). The test (or tests) were conducted, only to produce undesirable results. Afterwards, the project (supposedly called 'Project Rainbow') was canceled.As one can easily see, the actual facts are scanty. The Navy denies that any sort of experiment ever took place, and the ship's logs show that the USS Eldridge was nowhere near Philadelphia at the time the test was supposed to take place. Of course, logs can be faked, and the government and military has lied before about certain events in the interests of secrecy and national security (witness the Manhattan Project). On the other hand, research has shown no evidence of a "Project Rainbow", although there was a code name "Rainbow"; it was used to designate the Allied plans to combat the Axis in World War II and had nothing to do with any form of experimental technology. As a final note, it should be pointed out that even some basic research (the World Wide Web is loaded with relevant sites) will show that the entire 'experiment' may in fact be a massive hoax, a modern urban legend that has grown to fantastic proportions over time.
The Supposed True Story Of The Philadelphia Experiment

To the Navy, the test had succeeded beyond their wildest dreams. Not only had they rendered a ship invisible to radar, they had made it optically invisible as well, not to mention causing the vessel to teleport hundreds of miles in a matter of minutes. For the crew, however, the trip had been a nightmare. The test had managed to render the entire ship 'out of phase' with the surrounding universe, which is why it was able to travel from Philadelphia to Norfolk instantly. This phasing effect had drastic effects on the crew members. During the experiment, crew members found they could walk through solid objects, and when the field was shut off, men were found embedded in the bulkheads, decks and railings of the ship. The results were gruesome enough that some men went mad. Afterwards, several crew members simply vanished. A few disappeared into thin air; one, eating dinner with his family, rose, walked through a wall and was never seen again. Some men entered into what was called the 'Freeze'. This is where a man faded from view; unable to move, speak or otherwise affect his surroundings. Initially, the Freeze effect lasted only a few minutes to a few hours. Interestingly enough, invisible crewmen were still visible to other sailors who had survived the original experiment. After a while, the Freeze effect lasted for days or months, and became known as the 'Deep Freeze' (other terms include 'Caught in the Flow', 'Caught in the Push', 'Get Stuck', 'Go Blank', 'Hell Incorporated' or 'Stuck in Molasses'). The Deep Freeze could drive a man insane in very short order, and was only able to be counteracted if other crewmen performed a 'Laying on of Hands' technique to give the victim strength and allow him to recover from his affliction. Unfortunately, two men burst into flames while Laying on of Hands, burning for 18 days despite all attempts to quench the fire.
Seeing the horrible after effects of the experiment, the Navy discontinued all further research into radar and optical invisibility. The surviving crewmen were discharged as mentally unfit for duty and many were placed in insane asylums. However, science was not quite done conducting research on electromagnetic fields or radar and its affects on the human mind. Project Rainbow may have been disbanded, but the Phoenix Project was just getting started.
The Hellenic Navy still reports the Eldridge as having a launching date of the 25 June 1943, also confirmed in 'Jane's Fighting Ships' Volumes 1963 to 1985. Only the US Navy claims the date of launching as 25 July 1943. Makes you wonder ?
