In 1977, residents of Colares and nearby areas in Pará, northern Brazil, reported unusual lights and objects. The Brazilian Air Force investigated these accounts in an operation known as Operação Prato (“Operation Saucer”). Records, reports and other materials were later made available through Brazil’s National Archives.

The historical fact is that an official investigation took place. The existence of these records does not by itself establish that the reported objects were extraterrestrial. The documents are interesting because they show what witnesses described and how the Air Force recorded the accounts.

I made a documentary-style episode about this case for GM Mistérios. The narration is in Brazilian Portuguese, and the cinematic scenes and thumbnail are AI-assisted visual reconstructions, not genuine footage of the 1977 investigation.
