This is the July 1966 third edition of Dr. Leon Davidson's "Flying Saucers: An Analysis of the Air Force Project Blue Book Special Report No. 14", published by Ramsey-Wallace Corp. It reproduces early Air Force press releases, the 1953 CIA panel report, the 1966 Blue Book release and the full text of the May 1955 Special Report No. 14 with its tables and codes. Davidson also gives his view that the CIA was responsible for much saucer publicity.
