What the government released
This document is a U.S. Department of State diplomatic cable from the U.S. Embassy in Rio de Janeiro, Brazil to the Office of the Secretary of State in Washington, D.C., on November 20, 1963. This cable relays the findings of the scientific attaché at the American Consulate in Salvador, Bahia, Brazil, that a widely reported incident allegedly involving a crashed unidentified object was unsubstantiated, characterizing the reports as a fabrication originating in Rio de Janeiro.
The Consulate cites a lack of contemporary local reporting regarding the alleged incident, as well as contradictory reporting from local newspapers after the fact, as evidence that the published claims are unsubstantiated. The Consulate also cites a statement from the Brazilian Ministry of Aeronautics categorically denying that there was “any “strange object” in Conde [Bahia].” This correspondence follows a previous exchange between the Embassy and the Department of State, included in this collection under the title “DOS-UAP-D001.”

The case in this archive
This document is a primary source for the Conde sphere story, written up here at length from the contemporary record. The file and the case history are worth reading against each other: the document is narrower and more cautious than the account that grew up around it, which is usually the point.
Status of the case
This is an archival document, and it should be read as one. It records what a particular office believed, or was willing to commit to paper, on the day it was written — not a present-day finding. The mid-century investigations worked from witness testimony, sparse instrumentation, and the strategic anxieties of the early Cold War, and the great majority of the sightings they catalogued were eventually attributed to aircraft, balloons, astronomical objects, and misidentification. The All-domain Anomaly Resolution Office has made no modern determination about the incidents described here, and the document’s release is not an endorsement of the conclusions inside it. Its value is as evidence of how the United States government investigated the question, and of what it chose to keep.
