Bugger - the webpage no longer exists on that address, Earls, but I found it here:
CLICKY""I AM an American astronaut and a trained scientist. Because of my position people in high places confide in me. And, as a result, I have no doubt that aliens HAVE visited this planet."
You know, I may have seen a documentary with that ex-astronaut in, saying much the same thing.
I'm sure he released a book, too, which is always a bit dubious. But, maybe I'm thinking of the wrong guy.
Still, it is a scarily interesting subject.
