585: Operation Prato | Alien Vampires of the Amazon

In 1977, a remote Brazilian island experienced something unprecedented: systematic attacks on humans by unidentified flying objects. Victims reported glowing ceilings, beams of light, and blood extraction while paralyzed in their beds.

The Brazilian Air Force responded with Operation Prato (Operation Saucer), documenting hundreds of cases and gathering photographic evidence of unknown craft. Captain Uyrangê Hollanda led the investigation, eventually capturing images of objects hidden within the lights.

After decades of silence, Hollanda finally revealed what his team discovered, including his own terrifying encounter with the beings behind the attacks. Just weeks after his interview, he was found dead in his apartment.

The Colares incident remains one of the most well-documented UFO cases in history, raising uncomfortable questions about how governments handle first contact and why some files remain classified.
