Unidentified Flying Object Report — Panama Canal Zone, March 1958

This document is a collection of intelligence reports and correspondence regarding a series of unidentified radar contacts in the Panama Canal Zone between 9 and 13 March 1958. The primary incident involved two radar tracks observed by the 764th Anti-Aircraft Operations Center (AACC) and the 764th AAA Battalion. These objects were described as triangular, erratic in movement, and occasionally evasive. At one point, the objects were estimated to be three times the size of a freighter. Despite the radar returns, visual sightings by military personnel and a commercial flight were largely negative, though some personnel reported seeing red and green lights. The radar returns were noted to be similar to strong cumulus clouds, leading investigators to suspect anomalous propagation or weather phenomena. A T-33 aircraft from Howard Field was dispatched to investigate but reported negative results. The reports were reviewed by AFCIN-4E1, which concluded that the data was too limited for a definitive analysis, suggesting that the sightings were likely false radar targets caused by atmospheric conditions or weather, rather than material objects. The document includes detailed logs of the radar tracks, correspondence between intelligence units, and a map of the area. The final assessment emphasizes that the erratic nature of the signal returns and the failure to visually confirm the objects during daylight hours strongly point toward false targets or spurious signals rather than unidentified aircraft.
