I used to be heavily into this UFO stuff. What I found is that everyone knew these "facts" like the dummies but no one could ever point to the original data. The links all seemed to point back to the same people making the statements. That's when I started thinking it was bunk.
There has been some of that phenomenon, true.
That's not the case on the dummies in the Mogul proj. I'll see if I can track down a source or three later.
Actually, I think that phenomenon was not as widespread as you seemed to experience it as. I saw it mostly in say some sequences regarding Roswell etc. But in the broad topic area, I think there are plenty of direct sources who had first hand experiences in their jobs or otherwise.
Stephen Greer's DISCOVERY PROJECT certainly has plenty of the latter.
