by UFO History Buff & Author, Charles Lear
Brazil has a history of official UFO investigation almost as long as that of the United States. However, it has an official policy on disclosure that predates the U.S.’s by more than a decade. In 1954, the Brazilian Air Force started The First Confidential Inquiry into Unidentified Aerial Objects in response to the first major flap in that country. In 1969, the Sistema de Investigação de Objetos Aéreos Não Identificados (SIOANI) was established, and nearly 100 detailed case files were accumulated up until its termination in 1972. After this, in 1977, in response to reports of injuries and deaths as a result of UFO encounters in the area of Pará (mainly in Colores) Operação Prato was authorized by Colonel Protásio Lopes de Oliveira. This resulted in more than 2000 photos, 16 hours of film, and a 179-page report. The First Confidential Inquiry, SIOANI and Operação Prato files were classified for decades, but thanks to a freedom of information campaign begun in April of 2004 by the Brazilian UFOlogist and publisher of UFO Revista, Ademar José Gavaerd, many of the files were shown to him and other UFOlogists in 2005 as a prelude to releasing them to the general public. Then, in 2010, Brazil issued Ordinance 551/GC3, requiring every branch of the military and aviation sectors to collect and transfer all UFO reports to the Aerospace Defence Command in Brasilia along with any material proof by way of photos or video on a yearly basis. There, it is to be catalogued and made available to the public. Along with this, since 2012, the Air Force has periodically released declassified files through the Brazilian National Archives, and recently released 893 reports in May of this year. In this blog, we’ll look at the history of the Air Force investigation, the efforts of Gevaerd and other UFOlogists to gain access to the case files, and some of the most interesting (at least to us) cases (translated files can be found here) found within them.
