There's a sort of series of posts about the Contactees at UFO Mystic. All very good and interesting reading, including the comments from people like Red Pill Junkie. Van Tassel,Adamski, the FBI's involvement and "spying" are all topics discussed.
For myself, I consider the Contactee era a fascinating one, and it's a shame so many dismiss it all as mere kook stuff. I'm not suggesting that there were literal ETs from space that were dropping by for friendly chats in the deserts, but something was going on that defies the casual rejection of many UFO researchers.
