On the night of May 19,1986, an array of UFOs were spotted over southeastern Brazil, and the entire defense system was put on alert. The Air Force scrambled its most experienced pilots in F-5 and F-103 jets to intercept these objects. Colonel Ozires Silva, president of a Brazilian oil company, and his pilot, Commander Alcir Pereira de Silva, were flying an executive Xingu jet near Pocos de Caldas heading to Sao Jose dos Campos, when radars in different locations showed twenty-one UFOs in the sky from Sao Paulo to Rio de Janeiro. Silva and his pilot saw one of them and chased it for thirty minutes—a fast-moving, bright red-orange light that appeared to jump from point to point. They were not able to gain on it and eventually had to give up their pursuit. This was a situation in which numerous expert witnesses saw something and radar detected the same thing. Radar equipment can be affected by many different factors, and can present a false echo, but a false target appears very briefly and is easy to recognize because it disappears quickly. It's a different story when we have a regular trajectory to follow. Also, when we have more than one radar spotting the same target, we know it's serious. This equipment operates in different frequencies, so we have the correlation of independent readings from different sources. These data have nothing to do with human eyes. When, along with the radar, a pilot's pair of eyes sees that same thing, and then another pilot's, and so on, the incident has real credibility and stands on a solid foundation. A few days after these sightings, Brazil's Minister of Aeronautics, Brigadier Octavio Moreira Lima, called a press conference to explain what happened. He revealed that six jets had been scrambled from Santa Cruz AFB and Anapolis AFB, and some of the pilots had made visual contact, while all objects were registered on radar. The minister promised an official report within the next thirty days, but for some reason he changed his mind about releasing it. This was probably for some political reason, or maybe fear of panic because at that time the thinking was that the population might panic, if they knew. But in the meantime, the pilots and controllers were not prohibited from speaking about it. The events of that night were really amazing, and some of our simple questions have simple answers: Did the pilots see the phenomena? Yes. Did the radars spot them? Yes. Did Ozires and other military pilots see them? Yes. Did pilots in commercial aircraft see them? Yes. Do the a i mm . eo. times of the sightings correlate? Yes. Do the trajectories of the objects correlate? Yes; all of this was technically analyzed. So, did it happen? Yes, it did happen. o Everything was spotted by both aircraft radars and the radars on the ground. On-board radars operate in a microwave band, which is very narrow, while ground radars operate in a much broader band, so there's no risk of confusion or mistaken correlation. During this event, the military was not fearful of any sort of invasion. Jets armed with missiles took off and reached the objects in less
