Two pilots reported UFO sightings on the same route near Brasília-DF [1978]

AUG 23rd, 1978. Time: 00: 40Z. Duration: 15 minutes. The pilot of the PT KPB aircraft reported “with a wealth of details, the UFO sighting between the Paracatu and Cristalina positions” [on the route from São Paulo-SP to Brasília-DF]. The “Radar LP-23 do Gama” also detected the phenomenon, and the same happened to another plane,the Transbrasil QD-460, about an hour earlier, passing through the same position, reporting the phenomenon seen by PT KPB.


Below is the translation of the Flight Controllers’ report from Brasília-DF Airport on the event that occurred on August 23, 1978.

“When on duty on August 22rd, 1978, we were questioned by the Commander of QD-460 [Transbrasil aircraft], about the existence of traffic in the position, in relation to the clock,  9-hours. After our denial, he informed the traffic in the aforementioned position; when asked about the existence of such traffic, he again confirmed the existence of it and later reported that it had disappeared. This happened at 65NM outside Brasília.

After being transferred to the APP, he returned to our frequency and asked us about the range of our radar, which at the time generated doubts about what he wanted, if it was the position he was in relation to the supposed traffic or whether it was actually within radar coverage.

We inform him that it was 65NM. After the dialogue with that aircraft ceased, we initialized a target in the vicinity claimed and managed to place in direct control a target that had quality factor “6”, with speeds that varied between 133 KT / 804 KT. At no time did altitude indication appear.

In the absence of traffic, we tried to keep this target in direct control, awaiting the passage of another aircraft.

Approximately 35 minutes later, the PT-KPB, coming from São Paulo bound for Brasília, when authorized to start descending, did not copy the message from that Center in a timely manner and when it did, it was to inquire about the existence of traffic in the position identical to that previously informed by QD-460.

Reacting to our information about what Commander QD-460 had said, the Commander of PT-KPB informed us that: “I have an object view that is not consistent with those known, a shapeless mass, as if it were a halo, which sometimes remains at the same altitude and for others above the aircraft.” Frequency 125.2 has been blocked by an unidentified carrier since the QD-460 reported the existence of the alleged traffic. The QD-460 was at F310, and PT-KPB at level 280, and both came from São Paulo, the first landed in Brasilia at 00:30 hours Z and the (2nd) second at 01:15 hours Z. /L.C.M. 3S QAT CV and F.M.L.P. – CTA”
