Quick Info
In 1977, the small island of Colares and nearby beaches in northern Brazil became the center of one of the most violent and disturbing UFO flaps ever recorded. For months, glowing objects hovered over the region at night and fired beams of light at people. The beams caused severe burns, paralysis, puncture wounds, and in many cases appeared to suck blood directly from the victims’ bodies. Hundreds of residents were attacked.
Some were left with permanent scars and chronic health problems. The fear was so intense that families slept huddled together under blankets. Eventually the Brazilian Air Force launched a secret military operation called Operation Prato to investigate. What they discovered was so shocking that much of the evidence was suppressed. The Colares UFO Flap remains one of the darkest chapters in UFO history.
Timeline of the Colares Terror
- July 1977 Strange glowing lights begin appearing over Colares Island and the mainland coast. Fishermen report objects hovering silently above their boats at night.
- August 1977 The attacks begin in earnest. People are hit by beams of light while walking on the beach or near their homes. Victims suffer immediate burns, paralysis, and extreme fatigue.
- September–October 1977 The flap reaches its peak. Hundreds of residents are targeted. Many report feeling their blood being sucked through the light beams. Children and elderly people are frequently attacked. Panic spreads across the islands.
- Late 1977 The Brazilian Air Force launches Operation Prato. Captain Uyrangê Hollanda and his team spend months on the islands filming UFOs, documenting injuries, and collecting evidence.
- End of 1977 The attacks gradually decrease and eventually stop. The military operation ends. Much of the collected evidence, photographs, and medical reports mysteriously disappear or remain classified.
- 1997 Captain Hollanda breaks his long silence in a detailed interview, confirming the objects were real and under intelligent control. He dies by, allegedly, suicide shortly afterward.
The Attacks: What Victims Experienced
The beams of light caused immediate and painful physical effects. Victims described a sudden intense heat or pressure followed by complete paralysis. Many woke up with circular red burns on their skin and strange puncture marks. Some reported feeling as if their blood was being drained through the beam itself. The objects usually appeared at night and targeted people who were outside or near windows. The fear was so intense that entire families would huddle together under blankets, praying the lights would not return.
"The light hit me in the chest. I couldn’t move. It felt like something was pulling the blood out of my body. I was burning and freezing at the same time. I was sick for weeks afterward."
– A Colares resident, 1977
Many suffered long-term effects including chronic fatigue, recurring nightmares, anemia, and burns that would not heal properly. The psychological trauma lasted for years. Some victims refused to go outside after sunset for the rest of their lives.
Witness Testimonies: Voices from the Terror
The Colares UFO Flap was not just statistics and military reports. It was hundreds of ordinary people — fishermen, mothers, children, and farmers — who lived through something terrifying. Here are some of their own words from interviews and official records:
"The light came down like a fire. It hit me in the back. I felt a burning pain and then I couldn’t move. When it was over, I had a round red mark on my skin and I felt very weak, like all my blood was gone."
– João de Oliveira, fisherman, 1977
Many fishermen reported being targeted while working at night. They described the objects as glowing spheres or disks that would hover silently before firing the beams without warning.
"I was walking home with my daughter when the light appeared above us. It was bright red. The beam hit her first. She screamed and fell down. When I tried to pick her up, the light hit me too. We both had burns and felt sick for many days."
– Maria das Graças, resident of Colares, 1977
Children were not spared. Some of the most heartbreaking accounts came from young victims who were left traumatized for years.
"I was playing outside when the light came. It felt like fire on my leg. I couldn’t run. I saw a small round mark on my skin the next day. I still have nightmares about it."
– A 9-year-old boy, interviewed in 1977
Local doctor Dr. Wellaide Cecim Carvalho treated dozens of victims and became one of the most important witnesses. She documented the injuries and later spoke publicly about what she saw:
"I examined many patients with perfect circular burns, puncture marks, and signs of anemia. Some had radiation-like symptoms. The pattern was always the same. These were not ordinary injuries. Something was attacking these people."
– Dr. Wellaide Cecim Carvalho, local physician who treated victims
Even members of the military who participated in Operation Prato later confirmed the reality of the attacks. Captain Uyrangê Hollanda, who led the investigation, gave his most revealing interview in 1997:
"We saw the objects. We filmed them. We saw the beams hitting people. The injuries were real. This was not mass hysteria. These things were under intelligent control."
– Captain Uyrangê Hollanda, commander of Operation Prato, 1997
These testimonies, combined with medical records and physical evidence, paint a picture of a sustained campaign of terror that lasted for months. The fear was so deep that many residents still refuse to talk about that year openly, even decades later.
Medical Analysis of the Injuries
The physical effects of the light beams were not just stories. They were documented by doctors and left real, lasting marks on people’s bodies. The injuries followed a very specific pattern that doctors in the region had never seen before.
Most victims suffered **circular red or purple burns**, usually 2 to 8 centimeters in diameter, that appeared exactly where the beam had struck them. The burns were often deep and took weeks or even months to heal. Many people also had small puncture marks, as if something had pierced the skin. Blood tests frequently showed sudden anemia, with victims losing significant amounts of blood even though there were no open wounds large enough to explain it.
Dr. Wellaide Cecim Carvalho, the main physician who treated dozens of victims on Colares, kept careful records. She described the burns as “perfectly circular and unlike anything caused by fire or chemicals.” She noted that some patients developed symptoms similar to radiation exposure, including hair loss, nausea, headaches, and extreme fatigue that lasted for months. Several people required hospitalization.
"The burns were perfectly round, as if made by a precise instrument. The patients had low red blood cell counts with no visible bleeding. Some had puncture marks that looked almost surgical. I had never seen injuries like this before."
– Dr. Wellaide Cecim Carvalho, local physician who treated over 40 victims
During Operation Prato, the military medical team also examined victims. They confirmed the circular nature of the burns and the unusual anemia. Some reports mentioned elevated white blood cell counts, suggesting the body was fighting an unknown trauma. A few victims developed long-term health problems, including recurring skin lesions, chronic pain, and psychological trauma that lasted for years.
What made the injuries especially disturbing was how selective they were. The beams seemed to target specific parts of the body, often the chest, back, or legs. Some people were hit multiple times over different nights. The fact that the attacks continued for months and left consistent physical evidence across hundreds of cases made it impossible for local doctors to dismiss as mass hysteria.
To this day, some of the original medical records and photographs of the burns remain among the strongest physical evidence from the entire Colares flap.
Operation Prato: The Brazilian Military Investigation
As panic spread across the region, the Brazilian Air Force could no longer ignore the situation. They launched a secret official investigation called **Operation Prato**. Captain Uyrangê Hollanda, an experienced and initially skeptical officer, was put in charge.
Hollanda and his team spent several months living on Colares and the nearby islands. They interviewed hundreds of victims, photographed injuries, collected soil samples, and attempted to film the UFOs. According to Hollanda’s later testimony, they witnessed the objects on multiple occasions. He described seeing both small probe-like craft and a much larger “mother ship” that would release the smaller ones. The team reportedly filmed the objects firing beams at people and animals.
"We saw them many times. They were real. Some were small probes, others were very large. We filmed them. We saw the beams hitting people. It was not a hallucination or mass hysteria."
– Captain Uyrangê Hollanda, 1997 interview
The military collected medical reports showing burns, puncture wounds, and anemia consistent with blood loss. Some soil samples reportedly showed unusual radiation readings. Despite the extensive evidence gathered, most of Operation Prato’s findings were never released to the public. The files mysteriously disappeared or remain classified to this day.
In 1997, Captain Hollanda finally broke his silence in a detailed interview. He confirmed the objects were real, under intelligent control, and not human technology. Just months after the interview, he died by suicide. Many researchers believe he was under heavy pressure to keep quiet about what his team had discovered during Operation Prato.

Legacy in 2026
The Colares UFO Flap remains one of the darkest, quite frankly terrifying, and most disturbing chapters in UFO history. For months, unknown objects systematically attacked innocent people with beams of light that caused real physical harm. The Brazilian military’s own investigation confirmed the reality of the events, yet most of the evidence was suppressed. Colares stands as a chilling reminder that not all encounters are peaceful. Some of them are violent, extremely violent. And some of them leave scars that last an entire lifetime. This one really makes you think.
