Let me get this straight. The navy actually was able to make a ship disappear. This was in 1943. I wonder why this technology wasn't used, let's say, at Okinawa when the navy lost so many ships to kamikaze attacks. That was in 1945.

Rather than waste so much taxpayer dough on stealth technology, why don't we apply the Philadelphia Experiment to all our warplanes, ships and even troops.

I realize that the story has a wrinkle that the PE is deadly to the ship's crew. Perhaps science was not able to work out this small detail. If so, why couldn't we use the technology on drones that are used so much these days?

Dismal failure, considering the Cardinals beat them...

Was it a fiasco or an experiment gone terribly wrong? Somewhere there must be documentation of what was done, how was done and what the results (and mistakes) were. On the other had, we could have tampered with a technology that escaped our understanding and control. Enormous amounts of electricity and excruciating electromagnetic forces could have cause an accident that the government is still too embarrassed to acknowledge. The truth will eventually surface and will be quite surprising.

This one I would love to have revealed. Gotta be true.

yeah right! And there is a tooth fairy and Santa clause. do people really believe all this stuff? no wonder con men make so much money

Since the source of most of the information about this alleged incident is sailor's memories, it gives a whole new meaning to the term sea story.

I had never heard of this but im pretty sure if the U.S. Navy figured out how to make a ship invisible in the 1940's we'd have invisible Jets, Cars, Tanks, Guns and everything else by now.

There's very little proof that an actual ship was cloaked in invisibility or teleported, but the Philadelphia Experiment is still fascinating. There are several web sites that elaborate the tale with some -- ahem -- interesting additions such as Hitler's alliance with aliens, told by two crazy old men on a beat-up couch. If you get the time, Google for it...you're in for a laugh.

This smacks of some kind of deliberately false rumour propagated by Defense officials, either to frighten people into thinking that the US had more advanced technology than it really did, or as a psychological study to see just what level of absurdity can be attained and still convince people. I've also read several versions of the story, which is a hallmark of every urban legend.

Nothing mysterious about this one, the Navy does all kinds of dangerous experiments to us enlisted all the time.

This would definitely turn the world of science upside down if this could be proven. Invisible ships, time travel. The whole thing is pretty scary and fascinating. We just need the proof.

Neat mystery of a alleged military project to make a ship "invisible" by bending light around the object (I think); there was a great story on the History Channel about this supposed incident, explaining that the boat supposedly did disappear for a moment, re-appear elsewhere, and re-appear back in the original spot with the crew dead, embedded into the structure of the boat, insane, or gone altogether. Some people say that they've spotted glimpses of the missing sailors at bars, disappearing after a glance. Whether or not it is true, I don't know, but it's really interesting at least.
