The USS Eldridge
The USS Eldridge was alleged to have been the ship involved in Project Rainbow, otherwise known as the Philadelphia Experiment, on or around October 28, 1943. Legend goes that while participating in an experiment designed to render Navy ships invisible to magnetic mines, the Eldridge actually completely disappeared, reappeared off the coast of Norfolk, Virginia (some 200 miles away) minutes later and stayed there long enough to be clearly visible to those in the area, then transported back to its original location in the Philadelphia Naval Shipyard. Depending on the version of the story you hear, the Eldridge was also alleged to have transported forward in time to 1984 and connected with the Montauk Project while it was out of sight in 1943.
