A Força Aérea Brasileira e a investigação acerca de objetos aéreos não identificados (1969- 1986) : segredos, tecnologias e guerras não convencionais

Abstract

The objective of this research is to discuss the involvement of the Brazilian Air Force in the study and research of the phenomena related to unidentified aerial objects (Oanis) in the XX century. In 1969, the IV Air Zone created the Research System of Unidentified Aerial Objects (SIOANI), with the mission to carry out scientific research on the subject. Even with the closure of SIOANI in 1972, the Air Force in 1977, investigated the phenomenon during Operation Prato, in the northern state of Pará, upon request of the local authorities, who alleged a hostile attitude of the Oanis towards the native population. In 1986, the Brazilian Air Force undertook an interception mission in response to the invasion of national airspace by Oanis, an event that became to the public in a ceremony at the Presidential Palace, by decision of the Air Force minister at the time. Given these events, the objective of this research is to analyze the different positions of the Brazilian Air Force regarding the phenomenon of Oanis in the 20 th century, through its official documents, and in relation to the main evidence collected by the institution of these phenomena under the context of an air war and of the use of unconventional technologies.
