The Atomic Heritage Foundation's Version of the Philadelphia Experiment

 The Quonset Hut visitors from down under are particular stars in their areas of specialty. Friend Langley is the expert on the history of the development of atomic energy and on the effects of the atomic tests conducted in the South Pacific.  He was one of the first to educate me to the fact that America's quest for atomic energy  originated before the war at the Naval Research Lab as part of their search for a silent propulsion system.

By the time General Groves and the Manhattan Project came along, the Navy had mastered isotope separation via the thermal diffusion method. Their success was one of the most closely held atomic secrets for many years. So was the accident that killed three people in a demonstration put on for visitors from Oak Ridge. The full story of this documented "Philadelphia Experiment" is  now on the Atomic Heritage website.
