A 2004 Brazilian military document confirms that the Air Force maintains formal procedures and classified channels for handling UFO encounters-referred to officially as OVNIs (Objetos Voadores Não Identificados).
The letter, marked CONFIDENCIAL at the time, was directed to civilian researcher Cloves Roque Xavier, a representative of the UFO group UFO-Gênesis, in response to a formal public inquiry.
What stands out in this exchange is not only the acknowledgment of historical UFO investigation programs-but the clear admission that secrecy regarding these operations remains in effect.
“Procedures related to unidentified aerial phenomena are governed by specific, classified directives…”
🧾 A Civilian Inquiry with Military Acknowledgment
Xavier’s request listed several key military programs and directives known within the Brazilian UFO research community, including:
-
SIOANI (System for the Investigation of Unidentified Aerial Objects)
-
UPA 09, a 1969 protocol on incident reporting
-
RMA 205-1, a regulation on safeguarding classified information
-
Diretriz Específica 04/89, related to flight electronic protection
-
Operation Saucer, the 1977 Colares investigation
The letter from the Air Force did not deny the existence of these documents or operations-instead, it reaffirmed that many of the procedures remain subject to confidentiality and restricted access.
“The content referenced by the requester is indeed classified.”
📡 Transfer of Files to Aerospace Command
The response also notes that much of the documentation relating to UFO cases, including Operation Saucer, was transferred to the Aerospace Defense Command (COMDABRA) as of March 2000.
This supports growing evidence that Brazil’s military has centralized its handling of OVNI-related materials under higher command.
“All available documentation was transferred to COMDABRA on March 27, 2000.”
🔐 Continuity of Secrecy
While civilian researchers have long sought transparency regarding Brazil’s most famous UFO events, this document affirms that government secrecy continues, particularly where procedures or security infrastructure are involved.
The Air Force’s response cites its obligations to national defense and international protocols as justification for nondisclosure.
It does not attempt to dismiss or debunk the subject-it simply reaffirms that some files remain off-limits to the public.
