Conspiracy Theories That Still Secretly Haunt Society

The Philadelphia Experiment sounds like something from a wartime radio drama, which may explain why it traveled so well. The legend claims that in 1943, during World War II, the U.S. Navy conducted a secret experiment at the Philadelphia Naval Shipyard to make the USS Eldridge invisible or teleport it using advanced technology. The story became widely known after Carl M. Allen, also known as Carlos Allende, sent letters in the 1950s describing the alleged event.
