CLASSIC: The Philadelphia Experiment

Jul 8, 2026 · 1h 5m

Summary

Hosts Matt, Noel, and Ben investigate the Philadelphia Experiment legend, which claims the USS Eldridge was rendered invisible and teleported in 1943. They trace the story to letters from Carl Allen, a local eccentric with hypergraphia, who sent wild claims to ufologist Morris K. Jessup. Researcher Robert Gorman debunked the tale by proving the ship was elsewhere and Allen was a known fabricator. The episode concludes that the myth is an urban legend born from Allen’s imagination, not suppressed Navy technology.
