The official description
Embassy in Rio de Janeiro, Brazil to the Office of the Secretary of State in Washington, D.C., on November 14, 1963. This cable documents an effort by the Embassy to verify that the Department had assessed certain content published in a local newspaper as inauthentic, following a discussion on a poor-quality telephone connection the previous night. To ensure both offices were referencing the same reporting, the cable cites descriptive language paraphrased from the press, namely a “large metal manned balloon” and a “dead crewman aboard wearing [a] uniform or spacesuit with strange markings.”
