Adam, I agree with your sentiment. Nothing about Billy’s evidence impressed me much. And given than much of it appeared fake, I have an easier time believing that all of it was faked than believing that he met aliens (or even fake aliens).
But the nazi connection is interesting. The nazi connection always interests me.
My problem with the “nazi technology” theory is that it would seem impossible that no one else has been able to replicate nazi saucers since. Or — maybe saucer technology just isn’t as great as nazis thought it was? Maybe everyone in the world moved on to better, more efficient sky travel (stealth, etc.)? Thoughts?
Check out Joseph P. Farrell’s work called Saucers, Swastikas, and Psyops and The SS Brotherhood of the Bell. These will give you some good background info on the whole Nazi connection to the contactee movement, as well as info on the technology they were playing around with and brought to the United States post WWII. Also, check out Renato Vesco’s work.
If anything, it’ll give you something interesting to read and ponder.
