I'm just catching up with this episode and I found the guest generally cogent and non-crazy-seeming. Except...
You know how someone who gives credence to, say, Billy Maier or Stephen Greer, tends to undermine his general credibility, ups his gullibility quotient and generally, as you guys say, poisons the well? Well, his uncritical acceptance of the Roswell nonsense and in particular his photographic "analysis" of the memo in General Ramey's hand raises just such a flag for me. Have you seen the enlargements and analyses of that memo? The analyses I've seen on the web are exercises in pure wishful thinking and the powerful need to see patterns that just aren't there. Maybe he has access to better negatives. Maybe he's found a way to tease out more meaning from the photo. OK, show me. The stuff I've seen on this is just moonshine.
Up to that point, I gave the guy decent marks for credibility. After that, "Check, please!"
