The Philadelphia Experiment is an alleged military experiment supposed to have been carried out by the U.S. Navy at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania, United States, sometime around October 28, 1943. The U.S. Navy destroyer escort USS Eldridge was claimed to have been rendered invisible (or “cloaked”) to enemy devices. Did this really happen? Was time travel and alien technology involved? Or was this all a hoax? Tonight, we examine the facts behind this mysterious case with John Carman. Leave the world you think you know behind and join David Zublick at the Dark Outpost!
