re: What Robert Bigelow is up to
First link goes to Barry Goldwater's speech, not to any ufos.
Secondly, my opinion is that Bigelow and his group are "testing the waters" to pick up anyone bright enough that MIGHT have knowledge on ultra-propulsion systems.
And I don't think he's trustworthy. He works with too many spooks and I know people who HAVE worked for "them" and their ideas and projects have been lifted (IE: "stolen").
Good luck with that. He hangs with the likes of John Alexander.
