Alfred Bielek on C2C 1993 - Philadelphia Experiment

Alfred Bielik claims to have been on the ship that the Philadelphia experiment was done on. He was sent forward in time to 1983 where the US military claimed to have complete control over time/space technology. He goes into great detail about the technology involved.

Is the movie the Philadelphia experiment based off of this guy's testimony?

No, he says he was age regressed and he's not the man he was, so he wasn't involved with it as the man is is now.

It's actually based book by Charles Berlitz and William L. Moore called The Philadelphia Experiment - Project Invisibility (1979)
