Declassified US Department of State documents show the American government investigated an alleged UFO crash in Conde, Brazil, in November 1963.
Diplomatic records show that American agencies, including NASA and the US Department of Defense, were mobilized to verify Brazilian press reports claiming a metallic sphere containing a dead pilot had fallen in South America.
NASA, established five years earlier in 1958, was leading civilian space research for the United States, while the Department of Defense coordinated military intelligence and defense operations during the height of the space race.
The rumor originated from a radio broadcast by Rádio Tupi in Rio de Janeiro on November 8, 1963. The station reported that a large metallic sphere had crashed into the center of Conde, opening a crater four meters deep.
According to the radio broadcast, the object featured window-like openings covered by thick glass and contained a body of human appearance inside. The report stated that the alleged crew member wore heavy clothing marked with indecipherable inscriptions, creating widespread intrigue among the local population and prompting police authorities to investigate.
At the time, Rio de Janeiro operated as Brazil's national media hub, while Conde was a remote rural municipality located in the northeastern coastal state of Bahia, hundreds of miles to the north.
Diplomatic Investigation in Salvador
Following the broadcast and media coverage, the US embassy in Rio de Janeiro contacted the American consulate in Salvador, the capital of Bahia, to confirm whether the event had occurred. Messages were transmitted directly to Washington with requests that they be forwarded to NASA and the US Armed Forces.
The US consul in Salvador formally reported back that the story was a complete fabrication originating in Rio de Janeiro. Local inquiries in the Conde region confirmed that nobody in the area had seen any falling object or crashed vessel.
Although the Public Security Secretary of Bahia initially speculated that the reported artifact might have been a weather balloon, investigators found no evidence of any sighting or crash.
Brazilian military authorities also moved quickly to refute the claims. The Ministry of Aeronautics categorically denied that any strange object existed in Conde.
Press Reaction and Cold War Monitoring
On November 11, 1963, the newspaper Jornal da Bahia published an article mocking the episode under a headline describing the aircraft that was not there. A reporter sent to the municipality noted that the only event of any significance in the town was the transmission of his own dispatch, which he sent using an old Morse code transmitter at the federal telegraph office.
Morse code telegraphy, which uses electrical pulses to represent text characters, remained the primary long-distance communication link connecting rural Brazilian towns with urban newsrooms in the 1960s.
The newly released archives demonstrate how US officials maintained active monitoring of unidentified aerial phenomena across South America during the Cold War. Even when reports quickly collapsed into media rumors, diplomatic channels spent time and resources investigating foreign airspace reports.
