Documents / FOIA release
This Central Intelligence Agency briefing from 22 August 1952 presents the Office of Scientific Intelligence review of the Air Force flying saucer investigation, with attachments dated 14 and 19 August.

The briefing rules out US or Soviet weapons and space ships. Its main concerns are psychological warfare, false alerts to air defense, and civilian saucer groups.

General Sanford gave their interim conclusions in his recent press conference. These were that analysis of the cases showed "no pattern of anything consistent with any notice to the United States"; that the recent Washington reports were probably due to "temperate invasions"; and that the unexplained lightings could not have resulted from any experiments or tests conducted by the United States. so much for the history.
