A series of UFO sightings in Colares, Brazil involving luminous objects reportedly affecting civilians physically, leading to a Brazilian Air Force investigation known as Operation Prato.
Between 1977 and 1978, residents of Colares, a small town in northern Brazil, reported repeated encounters with glowing aerial objects that allegedly emitted beams of light causing burns, paralysis, and blood extraction-like symptoms. The Brazilian Air Force launched Operation Prato to investigate the phenomenon, documenting extensive witness testimony, photographs, and field observations. Military personnel also reported sightings of structured luminous objects performing controlled maneuvers over the region. The case remains one of the most significant officially investigated UFO waves in South America.
