On the night of 19 to 20 May 1986 radar operators and pilots over south-eastern Brazil reported as many as twenty-one unidentified objects, and five armed fighters were scrambled without an interception. The claimants in the file are almost all serving officers. This is the record of what was tracked and reported, not a verdict on what was over the Paraíba Valley.
EVENT DATE
May 19-20, 1986
LOCATION
São José dos Campos / São Paulo / Rio de Janeiro / Paraíba Valley · Brazil
The night runs from 19 into 20 May 1986 across the airspace of São José dos Campos, São Paulo, Rio de Janeiro and the Paraíba Valley. Radars and pilots are reported to have detected twenty-one unidentified objects over the region. Five armed fighters went up after them, F-5s and Mirages, and none of them made an interception. The objects are described as showing colour-changing lights, moving at extreme speed and performing manoeuvres the pursuing crews could not match. One detail sets the account apart from the ordinary run of radar nights: the objects are said to have responded to a controller signalling with the runway lights. Near dawn they went out over the sea.
What is on the record
The archive resolves six claimants from a single video on a single reporting channel. All six are identified by rank: Colonel Osiris Silva, Captains Armindo de Souza Viriato and De Freitas, Lieutenant Kleber, Sergeant Sérgio Mota da Silva, and a commander whose name appears in the file in two spellings, as Alcir in one place and Aucir in another. That the claimants are serving officers speaking about their own operational night is the substance of this entry.
What is missing is the paperwork. The archive holds no Brazilian Air Force documents for this case, no radar plots and no transcripts, so an event that turns entirely on instrumentation reaches the file as testimony about instrumentation. The file also carries no second reporting channel, which means the number of objects, the number of aircraft and the runway light exchange all rest on one carrier. That is a gap in what this archive has indexed rather than a finding about what exists.
Why it sits where it does
The entry grades L3 on multiple claimants describing one connected event. It would be a candidate for the document-corroborated tier if official records were in the file, and they are not. What the record holds is a consistent account, attributed to named officers, of a night on which Brazilian radar and Brazilian pilots reported objects they could not intercept. What those objects were is not resolved here.
