I bought the complete DVDs etc. of Colonel Prouty, originally for the JFK stuff, which is actually pretty thin. He has all sorts of other topics he covers, from his oft repeated Chiang Kai-Shek at Teheran incident to the one and only mention of UFOs.

Prouty didn't get the chance to expand on them, but what he said was:

1. 99% of what we're seeing is military (what we'd now call Secret Space)

and

2. any real aliens or contact would be covered up by the same elite that killed Kennedy, and that the secrecy would be compartmentalised, and the compartmentalisation would be controlled by the NSA and would lead to private enterprise.

He said it thirty years ago, closer to forty, originally, but it's one more tiny confirmation that slots into the current "Secret Space" craze- other than the claims of imminent disclosure...
