Unidentified Flying Objects (U) - USS HASSAYAMPA Sighting Report

This document consists of a series of naval messages and a routing slip regarding unidentified aerial phenomena observed by the USS HASSAYAMPA in the Philippines between May 5 and May 7, 1965. The initial report, dated May 5, describes two objects of first magnitude observed moving East to West at high speeds, maintaining close proximity. Thirty-five minutes later, the same or identical objects returned moving West to East. A second incident on May 6 involved three objects sighted through binoculars; one was first magnitude, and two were second magnitude. These objects moved toward the ship at high speed. Radar contact was established at a range of 22 miles and held for six minutes. The objects were observed to hover overhead for three minutes, during which they formed a circular formation. The objects then performed erratic maneuvers at speeds exceeding 3,000 knots. IFF challenges were made but not answered. A third observation period between May 5 and May 7 noted several other objects with characteristics of satellites. Captain David G. Robinson, in a memo to Major Quintanilla at FTD, noted that the data provided by the ship was too incomplete and conflicting for a definitive analysis. He stated that the duration and speed reports were incompatible and that the visual characteristics did not align with the radar data. Consequently, the objects were speculated to be satellites, though not Echo I or II, and the lack of equatorial crossing data prevented further confirmation. The final conclusion remained that there was insufficient data for a formal evaluation.
