Was Howard Menger, the sign painter from High Bridge, NJ, mentioned in that book? He was one of the first "contactees" I can remember. For some reason his back yard was "Landing Field Number 2" for the Venusian Air Force as I recall. His Venusian pals used to stop in for coffee when they were in the neighborhood....or so he claimed.
When I later told a classmate at college- a UFO contactee believer- that Menger had been institutionalized for mental problems he told me the government did this to keep Menger out of sight.
