Triangular UFO spotted near Curitiba in 2009

Summary

A report from the Brazilian Aerospace Defense Command (COMDABRA) describes a UFO sighting that occurred on April 18, 2009 at 13:45. The observer, a pilot, reported seeing a triangular object approximately 3 meters in span with a positive dihedral. The sighting lasted about 10 seconds, at an approximate altitude of 37,000 feet, 10 to 20 meters above the flight level. The pilot could not precisely determine the object's speed, but described it as metallic and without a defined shape. The sky was clear with no cloud formations.

The pilot contacted a military organization, and the report was recorded in COMDABRA's air traffic control system. Although no physical evidence or visual records such as photos or videos were found, the pilot's testimony was documented. The document, dated and signed, is part of COMDABRA's archives and no further investigations were conducted on the case. The sighting was described as "normal" in terms of sound, though the pilot mentioned the object reminded him of an aerophotometry model.
