There are many different interpretations and views of what really happened, or didn’t, when the U.S. Navy embarked on a project to de-magnetize warships beginning in 1943. What has become known as The Philadelphia Experiment is not a subject to be taken lightly. No matter what you believe about it or don’t, it’s a fact that several people have died or been killed as a direct result of claiming involvement with the experiment.
