Colares Brazil Operation Prato

Terror on the Island

In the late summer of 1977, the residents of Colares — a small, isolated fishing community on an island in the Amazon delta of Pará state, Brazil — began experiencing something that would terrify the population and ultimately draw the attention of the Brazilian Air Force. Strange lights appeared in the night sky over the island, descending from above and moving with apparent purpose. At first, they were curiosities. Then they became something worse.

The lights began targeting people.

Witnesses reported being struck by bright beams of various colors that descended from the objects overhead. Those hit described an immediate burning sensation, followed by paralysis that could last minutes or hours. The beams seemed to focus on exposed skin, and victims displayed injuries that doctors found deeply troubling: burn marks consistent with radiation exposure, small puncture wounds, and in several cases, symptoms of anemia and blood loss that had no conventional explanation. The locals, drawing on the only framework that made sense to them, named the lights chupa-chupa — “sucker-sucker” — because they believed the beams were extracting blood. The name stuck, and with it, a terror that consumed the entire island.

A Community Under Siege

The nightly visitations escalated through August and September 1977, growing more frequent and more aggressive. The population of Colares responded as any community might when confronted with an aerial threat they could neither understand nor defend against. Residents barricaded themselves indoors after dark. Bonfires were lit in open areas in the belief that bright light might deter the objects. Night watches were organized, with men standing guard while women and children sheltered inside. Some families abandoned their homes entirely, fleeing to the mainland. Several deaths were attributed either directly to the attacks or to the cardiac stress of living in sustained terror. The island’s medical practitioners documented victim after victim, building a clinical record of injuries that defied any prosaic explanation they could offer.

The Military Responds

By late 1977, reports from Colares had reached the Brazilian Air Force command in Belém. Rather than dismiss the accounts — as military organizations in most countries had done with UFO reports — the Brazilian Air Force took them seriously. In November, they dispatched a team to the island under the command of Captain Uyrangê Hollanda, an intelligence officer tasked with documenting and, if possible, explaining what was happening.

The resulting investigation, designated Operation Prato (Operation Plate, a reference to the disc-shaped objects), would run for approximately four months and become one of the most extensive military UFO investigations ever conducted anywhere in the world. Hollanda’s team included military photographers, medical personnel, and intelligence analysts. They conducted hundreds of interviews with witnesses, set up observation posts across the island, and on multiple occasions witnessed the phenomena themselves. Over the course of the operation, the team produced more than 500 photographs, hours of film footage, hundreds of documented witness testimonies, and detailed technical reports on objects that they could not identify or explain.

What the Military Found

The official conclusion of Operation Prato, contained in classified reports that would not surface for decades, was as straightforward as it was extraordinary: the phenomena were real, they were not conventional aircraft or atmospheric effects, their origin was unknown, and no explanation could be offered. The files were classified and locked away.

Captain Hollanda himself was profoundly affected by what he had witnessed. He had gone to Colares as a skeptical military officer conducting a routine investigation. He left as a man who had seen something that shattered his understanding of the possible. For twenty years, he said nothing publicly, bound by military protocol and the classification of the Operation Prato files.

Hollanda Speaks — and Dies

In 1997, after partial declassification of the Operation Prato documents, some photographs and reports were released to the public. The images showed luminous objects of various shapes hovering over jungle canopy and open water, captured on military-grade equipment by trained photographers. They were not blurry civilian snapshots. They were official military documentation of something the Brazilian Air Force could not explain.

Shortly before the release, Captain Hollanda gave a detailed interview in which he confirmed everything: the objects were real, the attacks were real, the injuries were real, and the photographs showed exactly what they appeared to show. He displayed his own copies of the Operation Prato photographs and described what he had witnessed during those months on Colares with a specificity and conviction that left little room for doubt about his sincerity.

Days after giving the interview, Hollanda was found dead. The official ruling was suicide. The timing — coming immediately after his public confirmation of Operation Prato’s findings — has fueled speculation ever since, though no evidence of foul play has been established.

The Evidence Endures

What makes the Colares wave nearly unique in the history of UFO cases is the convergence of multiple types of evidence. There are mass witnesses — an entire community of roughly 2,000 people who experienced the phenomena over a period of months. There is medical documentation of physical injuries, including burn marks, radiation-like symptoms, puncture wounds, and blood anomalies, all recorded by physicians who examined victims during and after the events. There are official military photographs taken under controlled conditions. There is the testimony of the operation’s commanding officer, given on the record before his death. And there is the Brazilian Air Force’s own classified conclusion that the phenomena were real and unexplained.

Skeptics have proposed mass hysteria, misidentified natural phenomena, or exaggeration amplified by cultural factors. These explanations face a difficult challenge: they must account not only for the witness testimony but for the photographs, the medical records, and the military investigation that confirmed what the witnesses reported. Mass hysteria does not produce radiation burns. Misidentification does not generate 500 military photographs of anomalous objects. And exaggeration does not prompt a nation’s air force to deploy an intelligence team for four months.

Operation Prato remains, by any reasonable measure, one of the most thoroughly documented and officially investigated UFO events in history. The Colares wave happened. The injuries were real. The military confirmed it. The only question that remains — as with so much in this field — is what it means.
