documentedagencyInternational UAP Agencies
Brazilian system for the investigation of unidentified aerial objects (Sistema de Investigacao de Objetos Aereos Nao Identificados), created in 1969 - predating FAB's 1977-78 Operacao Prato.
Establishes that Brazil's official UAP handling predates Operacao Prato; the Brazilian government has acknowledged SIOANI's 1969 creation. Bridges to fab_brazil and contextualizes operacao_prato as one operation within a longer institutional history.
