The last episode of Psi Factor that I saw had Matt Frewer explaining something to his dumb, eager assistant. Something about a vessel called the USS Eldridge that had been used in an experiment in 1943 to test some 'stealth technology'. The ship was engulfed in (as far as I could understand) an electromagnetic field, in the hopes that it would be undetectable by radar but, of course, all the crewmembers were killed. By that egregious electromagnetic field, obviously.
That sounds like nonsense, doesn't it? I'm no expert, but I don't think radar works quite that way, and I wouldn't have thought magnetism was all that harmful to people.
What he might have meant is the practice, pioneered by the British a bit earlier than that, of neutralizing the ship's magnetic field in order to avoid setting off magnetically-actuated mines. It wasn't really 'stealth technology' at all. It worked, moreover, and it did not cause any injuries to crew. All this 'USS Eldridge' stuff comes from an imaginative story that people just made up. It may seem like a small thing to be complaining about, but balderdash like this is just annoying and tends to ruin an otherwise mediocre tv show.
