Operation Prato

Record summary

Operation Prato was a Brazilian Air Force inquiry into reports of luminous objects and alleged injuries in communities around Colares, Pará, during a period often called the Colares flap. Reports included beams of light, nighttime activity and medical complaints, while investigators collected witness accounts and photographs. The episode matters because it offers an unusually substantial official file for comparison with later UAP investigations. Its evidentiary status remains disputed: many reports were secondhand, symptoms have competing explanations, and the surviving documentation is incomplete and mediated by later interviews.
