Agree: no need for those down votes. I don't happen to find anything particularly disconcerting in the paragraph you quoted. While I haven't looked into the damage aspect, there's enough credible witnesses whose testimony contradicts the official story of the flight path of the supposed jet that crashed (key given where exterior & interior damage occurred). But I found my own red flags. First, something the author wrote about Jesus, portrayed as a hoax. (Yeah, about the time I was enjoying Laurel Canyon-connected Linda Ronstadt's You're No Good, I read The Passover Plot, too.) Second, a book high on his recommended reading list that I found so offensive and so biased I threw it in the garbage. (If you saw my home, you'd know that I don't throw out too many books. P.S. It's now the text in some high schools.) Third, the (unnecessary) juxtaposition of (unnecessary) pics in Part 19 such that attempted to force you to see gruesome images (if you wished to read the text between them), which I found rather sick. This isn't a guy I'd wish to be friends with, his great stories and sense of humour notwithstanding.
Nonetheless, to the author's credit ~ for discerning readers, at least :) ~ I think he makes clear what is fact vs. supposition, facts easy to refute that could discredit him; and the facts do show many (too many) unusual and disturbing connections. Furthermore, those facts do seem to support some nefarious activities known to have occurred in later decades, if not to the present.
As one of the wittier of our founding fathers once said, "Believe none of what you hear, and half of what you see." I'm sure the self-proclaimed "disinformation-free" commentator would agree, as also Laurel Canyon-connected Harry Houdini!
