9 gen 1953 anni - 1/9/1953 Howard C. "H.C." Cross, director of exotic metallurgy at Battelle, addressed to Ruppelt "Jacques Vallee found the infamous 'Pentacle Memorandum' in Hynek's office. This was a highly classified document from January 1953, proving the existence of a separate [well-funded] study group of UFOs, and urging that the Robertson Panel be delayed until they had come to their own conclusions... In the mid-1960s, there was still no inkling among the wider public that there was any such study as this."
