Colares and Operation Prato

The Sighting

Through 1977, reports of strange lights spread along the rivers and coasts of Para state in northern Brazil, but they converged with unique intensity on Colares, a fishing town on an island at the mouth of the Amazon. Residents described objects of many kinds: silent discs, cylinders, and small probe-like lights that came in from the sea at night, low over the rooftops. The frightening part was contact: witnesses reported thin, concentrated beams, like a hot needle of light, that struck people, typically on the chest or neck, leaving small burn marks and paired puncture wounds, followed by weakness, dizziness, headaches, and in some accounts a feeling of blood having been drawn. Locals named the phenomenon "chupa-chupa," the sucker. The town doctor, Wellaide Cecim Carvalho, treated dozens of patients with unexplained superficial burns and marks; she publicly affirmed for decades that the injuries were real and unlike anything in her practice. Night vigils with bonfires and fireworks were organized; some residents fled the town. Mayor Jose Ildone Favacho Soeiro appealed for federal help.

The Investigation: Operation Prato

What happened next has no parallel: the Brazilian Air Force's I COMAR (First Regional Air Command, Belem) launched Operacao Prato, Operation Saucer, in roughly October 1977, an official military field study of an ongoing UFO flap. A small team under Captain Uyrange Hollanda deployed to Colares and surrounding villages with cameras and recorders. Over about four months the team logged hundreds of witness interviews across some thirty communities, took photographs of unexplained lights (estimates run to 500 photos), shot hours of film, and produced reports with maps, sketches, and object classifications. Then, in early 1978, the operation was abruptly terminated without public conclusions.

For two decades the files were denied. In 1997, the now-retired Colonel Hollanda gave a long filmed interview to Brazilian ufologists Ademar Gevaerd and colleagues, confirming the operation, describing far more material than was ever officially released, and stating his personal conviction that the phenomena were real, technological, and not of human origin; he described his own close-range sightings during the operation, including objects he watched maneuver at treetop height over the Baia do Sol. Weeks after the interview aired, Hollanda was found dead at his home, in what was recorded as a suicide by hanging. His family and colleagues have spoken of it since with evident pain and have generally attributed it to a private depression rather than to anything connected to the case itself, though the timing, immediately after his most candid public statement in twenty years, has understandably kept the loss entangled with the mystery he spent four months chasing. It remains one of the most somber chapters in the history of military ufology anywhere in the world, and researchers who cover it do so carefully, treating Hollanda first as a man who lost his life, and only second as a case footnote.

Beginning in 2004-2005, under pressure from Brazilian researchers, the Air Force declassified batches of Operation Prato documents, witness statements, sketches, and reports that confirm the operation's scope, though researchers maintain much material, including most photographs and films, remains unreleased. The released material includes the team's internal object taxonomy, sorting sightings by shape and behavior with hand-drawn sketches of discs, cylinders, and the small fast-moving probes, and log entries recording the investigators' own sightings, a level of granular, institutional documentation with no equivalent in the American, British, or Soviet case files of the same era.

The Fear on the Ground

What distinguishes Colares from nearly every other wave in this collection is the texture of daily life it disrupted. Fishermen altered their working hours to avoid the water after dark; families slept with lanterns lit through the night; church congregations organized prayer vigils specifically framed around the chupa-chupa rather than any conventional threat. Dr. Carvalho's clinic became, for a few months, something closer to a small emergency ward for an unclassified condition, treating patients whose wounds she could photograph and measure but not diagnose against any textbook she owned. The panic was serious enough, and sustained long enough, that it reached the federal government not through a UFO organization but through an elected mayor's formal appeal for help, a detail that separates Colares from cases driven by hobbyist ufologists: the request for Operation Prato came from civil authority responding to a public-health-adjacent emergency, not from believers seeking validation.

The Explanations

Skeptical analyses face an unusual problem at Colares: the primary documentation is military, contemporaneous, and voluminous. Proposed prosaic ingredients include misidentified aircraft, satellites, and meteors over a population under stress; mass psychogenic illness propagating the chupa-chupa narrative through isolated communities primed by folklore, Amazonian tradition includes light-beings and visagens; and self-inflicted or mundane injuries, insect bites, minor burns, reinterpreted under panic. The injuries were superficial; no deaths were ever rigorously documented as caused by the lights, though local accounts attribute at least two. Critics also note witness descriptions varied enormously, suggesting a composite of many stimuli rather than one phenomenon.

Against this: a serving military team, sent specifically to debunk or resolve the panic, instead accumulated photographs and first-hand sightings its commander considered genuinely anomalous; a physician documented injuries in real time; and the pattern, beams causing burns, recurs in credible cases elsewhere, most notably Cash-Landrum three years later. The Brazilian Air Force has never offered any explanation, only files.

Witnesses' Fates

Dr. Carvalho, the town physician, restated her testimony as recently as the 2020s: the burns were real, symmetrical, and beyond her medicine, and her patients were not hysterics but fishermen who wanted the sky to stop. Hollanda's death in 1997 closed off what researchers consider the single richest untapped source on the operation, since he alone among the team leaders had spoken candidly and on camera before he died; no comparably detailed insider account has surfaced from any other Prato team member since. Several rank-and-file soldiers who worked under Hollanda gave shorter statements to Brazilian researchers in the 2000s, generally corroborating the volume of sighting and interview activity without adding new interpretive claims.

Recent Fieldwork

Interest in Colares has been kept alive by a new generation of Brazilian UAP researchers working the same territory Hollanda's team once covered. Rony Vernet, a Rio de Janeiro-based electronic engineer and contemporary UAP investigator, has spent recent years running fieldwork expeditions across the Amazon basin, collecting fresh video and audio testimony from riverine and indigenous communities describing luminous phenomena strikingly similar to the 1977 chupa-chupa pattern, and pressing Brazilian authorities for further document releases; his 2024 fieldwork, reported alongside a separately organized December 2024 "Expedicao Chupa-Chupa" itinerary retracing Operation Prato's original ground across Para, produced new recorded witness accounts and renewed public and journalistic attention on the unreleased portions of the Prato archive. Neither expedition has yet forced a further declassification, but both illustrate that Colares functions less as a closed 1977-78 case file than as an ongoing regional phenomenon still being actively documented today.

Documentaries and Popular Culture

Colares and Operation Prato have been the subject of Brazilian television specials since the 1990s and feature in international UAP documentaries examining military-run UFO investigations, generally built around Hollanda's 1997 interview footage, which remains the only extended on-camera testimony from an operation commander anywhere in world ufology. The 1997 interview itself circulates in translated form on research archives and has become required viewing for serious students of the case, precisely because no comparable insider account exists for Roswell, Rendlesham, or any other major military-adjacent case.

Why It Endures

Colares is the most aggressive UFO wave on record, the rare case where the phenomenon is described not as evasive but as intrusive, physically marking human beings. Operation Prato makes it the best militarily documented flap in the southern hemisphere and a cornerstone of Brazil's uniquely open official engagement with the subject, a lineage running from Trindade through the 1986 "Official Night of UFOs" to the Senate hearings of the 2020s. The chupa-chupa's legacy is double: for researchers, a dossier of injury cases begging for medical follow-up that never came; for the people of Colares, a remembered season of fear, bonfires, and prayers under a sky that would not leave them alone, and for the case's chief documentarian, a debt the field has never quite settled, a commander who told the truth as he saw it and did not live to see what came of telling it.
