DOS-UAP-D001, Diplomatic Cable, Brazil, November 14, 1963

According to the releasing agency, this is an UNCLASSIFIED (subsequently declassified) U.S. Department of State incoming diplomatic cable from the U.S. Embassy in Rio de Janeiro to the Office of the Secretary of State in Washington, D.C., sent 14 November 1963. Following a poor radiotelephone connection the previous night, the Embassy sought confirmation of the Department's 'unqualified negative' regarding a local newspaper report. The report claimed that a large metal manned balloon had been found in the vicinity of Salvador around November 8, containing a dead crewman wearing a uniform or spacesuit with strange markings, and that a crater had formed on impact. The cable states the Embassy's understanding that an object had been sighted in that vicinity around that date and tentatively identified as a weather-type balloon, but that no such object had been found aground. The message was passed to Defense and NASA. It is signed 'GORDON' and references the science attache Simon-Pietri and International Scientific Affairs. A follow-on correspondence is filed as DOS-UAP-D002.
