I enjoyed the book and thought it was worth reading. I recall Corso does provide names in the book, but having people's names doesn't necessarily mean anything can be corroborated. I doubt Strom Thurmond was going to publicly say he was in the know about UFO's or general Trudeau. (I think that was his bosses name) It took Chris Mathews to call out Dennis Kucinich totally unexpectedly on live TV to even get him to comment on this stuff and even then he tried to hit the eject button and I don't blame him.
I wouldn't come to a final conclusion either way, like a lot of this UFO stuff it's probably got some truths in there combined with stuff that is geared to make Coros look more important or even things that Corso was lead to believe was true but maybe weren't.
The end of the book sort of paints a vague picture that thanks to Roswell and Corso's work, we defeated the Russians and the Aliens, which IMO seems pretty outlandish, nothing is that simple, perhaps the publisher wanted to have a simple summary at the end that showed the significance of this stuff, I don't know.
However, it would not surprise me if in fact the deep black world has acutally created Star Wars tech in space that actually does work and is in response to UFO's. I thought that was a very interesting part of the book. By the way, what is the conscensus on this youtube clip which reminds me of this part of the book -
I'm still on the fence about how factual the book is, but I think it opens up a lot of possibilities. I don't disagree with anyone for ruling out the book because of the several inaccuracies that have been pointed out and the relatively small amount of backup to support the claims and the historic evidence which actually contradicts his claims, but I tend to leave open the possibility that there is significant truth in the book. Given the fact the guy wrote the whole thing by hand (harder for the editor to understand what was written) and was elderly and sick and had 1 day to proofread can help explain some of the more minute errors. I can't even remember people's named 2 minutes after shaking their hand much less recall the title of someone I worked with 30 years ago while I was in very bad healthy. Unfortunately, this is a field with so much bullshit that any errors or personal subjective spin can and should question credibility, even if someone is being truthful for the most part.
For what it's worth, Paul Hellyer said after he read the book he called a high level US military general (I think that was the rank but don't remember) to get his take on the book and this person told him the book was 100% true. As the Defence Minister in Canada and the equivalent of Deputy Prime Minister during the Cold War I bet Hellyer had some high up contacts he could call to corroborate and in fact did.
