Monthly Report of UFO/UAP Sightings and Occurrences - CINDACTA I, August 1986

This document is a compilation of reports, correspondence, and monthly summaries from the Brazilian Air Force's First Integrated Air Defense and Air Traffic Control Center (CINDACTA I) regarding Unidentified Aerial Phenomena (OVNI) observed between late 1985 and August 1986. The reports detail numerous sightings by both military and civilian pilots, as well as radar detections by various ground stations. Common characteristics reported across these incidents include objects appearing as bright lights or stars, often changing color (white, red, green, yellow, orange, blue), and exhibiting intelligent behavior such as rapid acceleration, hovering, and following aircraft. In several instances, pilots attempted to intercept these objects, but the objects would either disappear or maintain a distance. Radar data often showed 'plots' rather than solid tracks, and ground controllers frequently struggled to confirm these sightings with radar equipment. The document includes detailed questionnaires filled out by witnesses, including pilots and air traffic controllers, providing specific data on the sightings. The official conclusion of the command, as stated in the final reports, is that the phenomena are solid, reflect intelligence, and are capable of complex maneuvers, noting that they are not necessarily manned. The document also highlights the operational procedures for reporting and investigating these sightings, including the use of video recording and the involvement of the Air Defense Operations Center (CODA).
