I have checked the other side of the coin it's heads....And as far as the website Bad UFOs is concerned did you read the article or just automatically invoke your bias? Sheaffer writes a lot of good stuff on that blog I follow it as a matter of fact...I also follow Nick Redfern, Timothy Green Beckley, Tim Swartz and a host of others who are not anti UFO (skeptical)....
I have books by Sheaffer, Redfern, Beckley, Klass, Prothero, Callahan and others....
