In Brasília-DF and São Paulo-SP, air traffic controllers detected several UFOs [1984]

NOV 1st, 1984. Time: 00:31. Duration: not determined. At 00:31 on November 1, 1984, the Brasília-DF Area Control Center [ACC-BS] activates the São Paulo-SP Approach Control [APP-SP] to find out if there were any aircraft flying, because they were “detecting a runway 5 NM southeast of São Paulo, at a speed of 13kt [24km/h], constantly varying from the bow”. At that time, APP-SP had not yet detected anything.

At 00:40, the ACC-BS was already detecting 2 “plots”: one to the southeast of Itanhaém-SP and the other to the vertical of São Paulo-SP. This time the APP-SP confirms the contacts. Meanwhile, at TWR-SP [São Paulo Airport Control Tower] operators were seeing “with a binocular, a white and yellow light”.

The TWR-SP, by that time, had already registered 3 phone calls reporting the UFO, and APP-SP ” detected not only 2, but several unidentified ‘plots‘”.

00:40 – “APP-SP has 2 contacts: one on the 155º radial, 8 to 9NM; and the other was on top of Santana-SP and moved to the 340/343 radial at 16/17NM”, while the ACC -BS now had a plot near São Paulo, without Santana. “APP-SP even had 4 large primary ‘plots’ in the northern sector between 8 to 16 NM outside São Paulo”.

At that time, the two control centers in Brasília and São Paulo “simultaneously lost and recovered contact with UFOs”. However, at 00:46, APP-SP had 7 ‘plots’ in the São Paulo region and 4 ‘plots’ in the north, up to 8NM. According to the report, the primary ‘plots’ were the size of a Boeing. Radar contacts have also been reported to the south of Santos-SP. Gradually the reports were diminished until nothing was reported from aircrafts or control centers that day.
