In 1977, in the interior of Pará, on the island of Colares, one of the most intriguing episodes in Brazilian ufological history occurred. A phenomenon considered supernatural marked the region: intense lights coming from the sky, with silhouettes similar to spaceships, flew over the community and attacked residents with beams of light. These attacks caused burns, discomfort, malaise, and reports of blood sucking, generating fear and commotion among the local population. Given the seriousness of the events, the Brazilian Air Force was called in and began the official investigation known as "Operation Prato". The case gained international attention, being recognized as one of the largest and most impactful ufological episodes in the world.
