Os Documentos Oficiais da Força Aérea Brasileira (Coleção Biblioteca UFO 2)

This document is a compilation of official Brazilian Air Force (FAB) bulletins, memoranda, and correspondence regarding the investigation of Unidentified Aerial Phenomena (UFOs/OANIs). It details the establishment and operation of the SIOANI (System for the Investigation of Unidentified Aerial Objects), created in 1969 under the 4th Air Zone (COMAR) in São Paulo. The document provides a historical overview of how the FAB managed UFO reports, transitioning from the SIOANI to the NUCOMDABRA (Nucleus of the Aerospace Defense Command of Brazil) by the late 1980s. It includes internal directives, such as the 'Diretriz Específica 04/89', which established standardized procedures for military control organs to follow when encountering UFOs, including radar monitoring, video recording, and the use of a standardized questionnaire for witnesses. The compilation also features numerous case reports (CI-001 through CI-070) from the late 1960s, detailing witness accounts, physical descriptions of objects, and the military's attempts to categorize these sightings. The document highlights the military's dual approach: maintaining secrecy regarding official investigations while acknowledging the need to systematically document and analyze phenomena that could not be ignored. It includes correspondence with civilian researchers, such as Osni Schwarz, demonstrating the military's interaction with the civilian ufological community. The document serves as a record of the institutionalization of UFO research within the Brazilian military, emphasizing the importance of scientific rigor, the collection of physical evidence, and the maintenance of operational security.
