CIA File of the Day
Flying Saucers
A 15 March 1949 U.S. government office memorandum on flying saucers. After a rapid review of documents, the writer notes that no suggestion is made that many of the reports may be free meteorological sounding balloons, and argues that if these flying saucers are a U.S. development, it is extremely unlikely they would be found over the United States, because U.S. developments would be closely coordinated with the USAF or commercial designers.
