A few years ago, we covered a revealing post where Dr. Allen J. Hynek (from project Bluebook) apparently confided his revelations about Dr Sagan to his former associate Paolo Harris - "I know UFOs are real, but I would not risk my research (College) funding, as you do, to talk openly about them in public.’
Linda Moulton Howe, investigative researcher from Earthfiles.com has uncovered a quote From March 6, 1996, letter by astronomer Carl Sagan to U. K. Ministry of Defence, in which he allegedly quotes that:
"evidence has been uncovered showing some farmers have been paid considerable sums of money to destroy the real crop circles when they appear, and groups encouraged to then make hoaxed replicas.”
Coming from such a well respected man in the scientific community this is indeed a revealing revelation.
However it is not a shock to many, with the grandfather of crop circle research, Colin Andrews often explaining that crop circles were under deep surveillance from the 1980's and onwards with extensive CIA and UK military involvement in an active disinformation campaign to deter public attention and discredit researchers of the topic.
