The encounter of a gigantic UFO by Brazilian pilot Haroldo Westendorff


Most sightings occur with small discoid objects thus with few crewmembers. Occasionally, a large ship conveniently called "the mothership" is seen. This case is emblematic because a "mothership" was seen in midair by a Brazilian pilot and then flew around it several times with his light aircraft. The pilot fled when the giant UFO released three small discoid objects. This stunning encounter between a light aircraft and a giant UFO was sighted and registered by radar at the city of Pelotas airport with several other witnesses.

The Brazilian, Haroldo Westendorff, is not only a pilot but also a gaucho entrepreneur who runs a rice processing plant, a transport company and a pet food factory. In his spare time, he often flies his own airplane and was in one of those moments of leisure that the businessman had an intriguing experience.

The experience of Haroldo Westendorff:

On October 5, 1996, at nine in the morning, shortly after breakfast, Haroldo Westendorff took off from the Pelotas International Airport for a ride in his light aircraft (Tupy PT-NTH). The sky was clear and sunny that day that allowed a flight with an excellent view. At about ten o'clock, when he was about 15 kilometers from the airport, near the city of São José do Norte and flying over "Lagoa dos Patos" (literally: Ducks' Lagoon), he ran into a humongous unidentified aerial object, flying over the island of Saragonha at an altitude of 1,800 meters. The shock was so great that he did stutter for a few seconds. But when he recovered from the shock, the businessman was able to approach the object, where he remained for about twelve minutes carefully examining the ship’s surface to make a very detailed report on the anomalous object.

Haroldo affirms that the object had a base the size of a soccer stadium, about 100 meters in diameter and 50 to 60 meters high. He also says that it had the shape of a pyramid with eight sides. Each side had three protruding domes. The businessman remained flying around the UFO at a distance of approximately 100 meters. He took three laps around the craft to observe its details well. It had a metallic appearance, with a smooth bottom. The ship revolved around its own axis heading slowly toward the sea.

During the time the witness remained around the UFO, he noticed that it did not make a hostile move. One of the most memorable moments of the experience was when suddenly a hatch opened on top of it and three discoid objects came out. The discs left in a vertical position, they inclined at 45 degrees angle and shot up at an impressive speed.

At this time, Haroldo maneuvered his light aircraft to observe the interior of the mothership, which was still opened on top of it. This was when this gigantic craft began to emit some reddish rays through the opening that scared the pilot, which prompted him to move away from the craft. At this time, the huge craft ascended vertically at an amazing speed, without wind, without a roaring sound and with no other physical reaction.

This event makes an impression not only by the richness of the details described by a pilot with over 20 years of experience, but also by the quantity and quality of the witnesses who claim to have seen the same ship.

During the second lap around the ship, Westendorff used the plane's radio to inform "Infraero" (Brazilian Company of Airport Infrastructure) control room at Pelotas International Airport of what was happening. He informed the operator Airton da Silva Mendes that he had seen to the east "a grayish pyramid form object with eight sides, on the horizon." With him were the assistants of port services, Gilberto Martins dos Santos and Jorge Renato S. Dutra who visually confirmed the flying object and together tried to identify it.

Westendorff also contacted "Cindacta II" (Integrated Air Traffic Control and Air Defense Center), in Curitiba, in the state of Paraná, which is responsible for monitoring the skies of southern Brazil. The response received was that there was no record of anything unusual on radar, but could detect the presence of the plane.

The Ministry of Aviation maintains an undercover investigation on the ship sighted by Westendorff. A sergeant of the Canoas Air Force Base traveled to Pelotas to collect the testimony of the businessman and of the Infraero officials. The sergeant asked for anonymity, but spent an afternoon at the airfield where he heard the eyewitness accounts and took knowledge of the episode.


This case is undoubtedly one of the ufology stories with very precise details of a UFO coming from someone who has been a pilot since the 1970s, and from one who has had a pilot license since the age of 19. In addition, Westendorff is also a two-time Brazilian champion in aerobatics. It is obvious that Haroldo Westendorff encountered something unusual when piloting his light aircraft on a clear and sunny sky, allowing an excellent visibility.

Although there have been many unexplained sightings in the town of Lajas, the situation there has been hyped by the amount of lies and exaggeration by a group of so-called, "ufologists" who ignore other areas of Puerto Rico to promote tourism in Lajas. That was evident when my wife and my daughter confronted a terrifying experience in the town of Aguada with extraterrestrials and that group of charlatans refused our plea for help. Of course, if it happened in Lajas they would have jumped on the opportunity for fame and tourism for that town. Those hoaxes and lies were approved and sanctioned by the then mayor of that town who named route 303 "The extraterrestrial route". The idea of building an "UFOport" (ovnipuerto), “la llorona sightings" and the biggest hoax of them all, "that a UFO crashed there" all this could only be found in a science fiction novel.
