Operação Prato: The Brazilian Air Force's 1977–1978 Colares UFO Investigation and Its Aftermath

To the point

Operação Prato was a 1977–78 Brazilian Air Force investigation into UFO sightings in Colares, Pará, led by Captain Uyrangê Bolivar Soares Nogueira de Hollanda Lima, which found no solid evidence of unusual phenomena despite residents reporting lights and injuries called “Chupa Chupa” and urging help from Mayor José Ildone Favacho Soeiro; two phases yielded photos but no conclusive proof, official records are in the Brazilian National Archives, Hollanda gave a 1997 interview and was found dead months later fueling conspiracy theories, and some ufologists like Jacques Vallée discussed the case while others claimed effects not supported by the findings.

Operation Saucer, a Brazilian Air Force investigation conducted between 1977 and 1978 into alleged UFO sightings in Colares, Pará, concluded with no unusual phenomena; despite local reports of lights nicknamed 'Chupa Chupa', vigils and fires, and a mayor who sought federal assistance, it was led by Captain Uyrangê Bolivar Soares Nogueira de Hollanda Lima and unfolded in two phases from October to December 1977 during which photographs were obtained but no conclusive evidence emerged; official documents are archived in the Brazilian National Archives; Hollanda gave a 1997 interview about his experiences and was found dead three months later, fueling conspiracy theories; while some ufologists claimed injuries or radiation-like effects or blood-sucking incidents, these claims are not supported by official findings; Jacques Vallée is cited among ufologists who discussed the events, making it a notable episode in Brazilian ufology.
