CIA Cable on Leon Davidson and the 'Space Message' Hoax Inquiry

This declassified CIA cable, released via the CIA Reading Room, reports on a face-to-face contact with Leon Davidson while he was in Chicago for a scientific meeting. According to the cable, Davidson was writing an article for a space magazine and wanted either the translation of a 'space message' and identification of the emitting station to prove the message a hoax, or permission to reproduce government letterheads (the CIA's and ATIC's) in his article to illustrate government avoidance of his inquiries. Davidson reportedly stated he had received no satisfactory answer to his requests to the agencies in nearly a year. The officer told Davidson he would communicate with him shortly, either supplying the requested information if possible or explaining that nothing further could be done, and advised Davidson that using government letterhead without express agency permission would be imprudent — advice Davidson agreed with. Described as 'calm and pleasant but very determined,' Davidson prompted the sending station to 'bow out of this thing' while urging that headquarters and ATIC concern themselves with the man and try to satisfy him, stressing a commitment to communicate with him. The text is heavily garbled from OCR of a degraded original.
