During “Night of the UFOs,” Brazilian pilots come across “11,500 mph craft.”

In Brazil’s legendary “Night of the UFOs,” fighter aircraft chased enigmatic luminous objects, some of which were 300 feet wide and moving at 11,500 mph.

Air force officials acknowledged that “there is no explanation” when five perplexed pilots claimed that they saw 21 objects arrive and go, along with hundreds of troops on the ground.

What transpired is expected to be discussed at a session on UFOs this week in the Brazilian Senate.

The occasion follows a congressional hearing in response to the now-famous “Tic-Tac” video, which was shot from US Navy fighter planes and depicted weird, enigmatic objects darting in the sky.

But the tale of what happened on a Brazilian night a decade before those films were made is just as bizarre.

Hundreds of witnesses, including the top military officers in the nation, saw weird objects that appeared to be moving at a horrifying pace over the course of many hours.

The items played “cat and mouse” with the pilots, forcing them to look at things in front of them that didn’t show up on their aircraft radars, and sometimes the other way around.

On the evening of May 19, 1986, Brazilian air force air traffic controller Sergeant Sergio Mota da Silva reported the first indications of anything strange.

From the control tower of an airport close to the city of Sao Paulo, he noticed a light in the sky.

He claimed that it is simply standing there and does not move up or down, to the left or to the right.

The controllers at Sao Paulo’s international airport informed Mota that no aircraft were flying toward his airfield.

He claimed that at one point he turned up the brightness after dimming the runway lights to cause the objects to move away from the control tower.

“I’m not sure if they were attempting to engage with me. I am aware of their sophisticated behaviour, he told the BBC.

Around 2,000 cadets and officers from an air force training facility nearby reported seeing the lights around 8 o’clock.

Then, an hour later, when it was landing at the same airport, a plane being flown by the president of the aircraft manufacturer Embraer noticed multiple objects in the sky.

Two passenger flights, one of which was flying over Brazil’s interior, also reported seeing the lights in the sky.

The air force subsequently sprung into action and sent its jets to intercept the objects, but it proved to be a difficult assignment as the pilots became confused by what was transpiring.

The radars occasionally did not pick up anything, despite the pilots having visual contact with the targets, according to Mota.

Other times, even though the radars detected the existence of objects, the pilots were unable to see them.

Three aircraft were initially sent up, one of which, a Mirage F-103, took off just before midnight with Captain Armindo Sousa Viriato at the controls.

His high-performance warplane quickly reached 1,000 mph, but when he got closer to the UFO, it sped to a speed he estimated to be 11,500 mph, or 15 times the speed of sound.

A few years later, he added in an interview, “If there is a plane that can develop that speed, I don’t know of it.

Lt. Kleber Caldas Marinho was the pilot of an F-5E that was the first to take off earlier, about 10:30 p.m.

The target “stopped coming towards me and started to ascend,” he said as he got closer to it.

Ademar José Gevaerd, a Brazilian UFO researcher, thinks that night alien technology “immensely superior to ours” was on exhibit.

They never attempted to harm us. With us, they engaged in “cat and mouse,” he claimed.

The amazing things happening in the skies were not going unnoticed on the ground, though.

Adenir Britto, a photographer, received a tip that a “flying saucer” was floating overhead while he was working the night shift in his newspaper’s office.

He walked outside with a reporter, initially thinking it was a joke, then to his surprise saw the things and started shooting.
