UFO Case Report:

Pilot encounters giant pyramid-shaped UFO over Pelotas, Brazil

Date: October 5, 1996
Location: Pelotas, Brazil

Brazilian pilot Haroldo Westendorf, 39, was flying over Pelotas when he encountered an enormous pyramid or cone shaped UFO, with 8-10 sides; it was 100 meters in diameter and 70 meters high. Westendorf was able to fly around the base of the object three times, at one point coming as close as 40 meters. Then, out of an opening at the top of the craft, a smaller classic disc-shaped UFO emerged and flew off at tremendous speed. Three air traffic controllers and others on the ground also witnessed the event.

[Excerpt from the article]

Perhaps the most impressive UFO story told during the recent Brazilian World UFO Forum was that of Haraldo Westendorf, who made news headlines a year ago when he allegedly flew his private plane within a few dozen meters of an enormous unidentified flying object.

Westendorf is 40 years old, a father of three children and a successful businessman. He is also an avid private pilot rated for acrobatic flying. The following account is based directly on his one-hour presentation at the Brazilian UFO conference, which included several detailed illustrations.

Westendorf says he took off in his single-engine Piper Apache [correction: the plane was actually an Embraer EMB-712, the Brazilian version of the Piper Cherokee Archer II] from the city of Pelotas near the southernmost tip of Brazil on the morning of November 5, 1996. It was to be a routine recreational flight of the kind he takes for fun whenever time allows.

On this occasion, he had been in the air only about 12 minutes and was flying at an altitude of 5,000 feet over a large lake some five miles southeast of Pelotas when he saw ahead of him an enormous aerial object. The time was about 10:30 a.m.

He radioed the Pelotas tower to learn if they could see the object from the ground. They confirmed that the object was visible to them and asked him for a close-range report. Westendorf then decided to fly as close as he could.

Westendorf emphasizes that he did not believe in UFOs and says this accounts for his initial willingness to fly close to the object. He didn't know he might be in danger.

When he got close to the object, he realized that in his twenty years of piloting experience he had never seen or heard of anything like it. Since he had done stunt training in the United States and had also flown in France, he had become acquainted with some very advanced and exotic aircraft. But he knew that this was not an airplane.

Westendorf showed several detailed color drawings of the object, with his own plane drawn to scale alongside it. He describes the object as a faceted cone, flat on the bottom with a rounded point on top. On each of the eight or ten sloping side panels were three large bulges, like triangle-shaped bay windows on the side of a house -- but they did not look like windows. The entire surface was brown in color. The structure was about 70 meters (225 feet) high and about 100 meters (325 feet) in diameter, big enough to fill nearly an entire soccer field if landed. His own plane, less than 6 meters wide, was tiny by comparison.

Westendorf says he spent about 12 to 14 minutes in close proximity to the object, trying to see as much as he could. Although the Pelotas air tower does not have radar, he believes the airport radar at Curitiba (nearly 450 nautical miles northeast of his position) tracked the whole encounter. However, officials at Curitiba deny this (see below).

The object was spinning around slowly and moving southeast toward the nearby seacoast at a speed of about 60 nautical miles per hour. Westendorf managed to fly entirely around the base of the object three times. At one point, he says, his wingtip came within about 40 meters of the object.

After his third lap around the object, Westendorf noticed that the rounded top seemed to disappear, leaving what looked like an open hole at the top. Then he saw, emerging from inside the object, a classic flying saucer. It rose sideways, its long axis vertical until it cleared the top of the larger object, then tipped down to assume its normal orientation and departed at tremendous speed. Westendorf said that this saucer was about 10 meters in diameter, or nearly twice as wide as his own plane, and he thinks it flew away at more than Mach 10. The saucer showed no indication of noticing Westendorf's presence nearby.

As soon as the saucer disappeared, Westendorf decided to try to fly over the top of the object. Brazilian media later reported that he wanted to fly his plane into the interior of the object, but he says he never even considered that. He only hoped for a peek through the opening.

To get more altitude, he flew his plane several hundred meters away from the object, turned around and began a steep climb. He noticed that the object was now rotating much faster. Then he saw brilliant beams of red light shoot from the top of the object toward the sky. He quickly abandoned his plan to fly over the top.

Then, to his amazement, the object rose straight up at tremendous speed. For the first time, Westendorf was scared, because he believed the object's rapid acceleration might produce a shock wave of turbulence that could overwhelm his own plane. As a trained pilot, he knew that air traffic controllers recommend staying at least three minutes behind a large aircraft to avoid such turbulence. He estimated that the unidentified object probably weighed at least three times as much as a 747 jumbo jet, so its shock wave should be huge -- and he was only a few hundred meters away.

He quickly began emergency procedures in case his plane went into a spin or a stall. But to his surprise, he did not encounter any turbulence.
