Problem is all the threads on this subject, either fall off very quickly or get shilled and killed.

In previous posts there were links to loads of different pages, some purporting to go back to the 60's. In these there were a few people who when it was mentioned back in the 60's said they were all given a visit from shall we say certain alphabet agencies (for want of a better term)how true this i or not, however Time ran a story about it, may even be mentioned in posts above.

What doesn't help is that all the services dept's, have also run 'Black Knight' programs, so trying to ever find anything is like a needle in a haystack, i believe NASA even has photos and they are accessible from their site, just go and look through some of the previous threads.
