Project 10073 Record Card and Correspondence — Aquadilla, Puerto Rico, December 1960

This document consists of a Project 10073 Record Card and associated correspondence regarding a UFO sighting reported in Aquadilla, Puerto Rico, on December 17, 1960. The witness, who identified himself as an ex-professor of science, observed an object with the intensity of a first-magnitude star moving in a straight line from the west to the southeast. The witness noted that the object, which displayed a bright blue light, appeared to 'wiggle' and change its path at the end of the ten-minute observation. The witness explicitly stated his opinion that the object was not a balloon or a rocket, but possibly a satellite. The official Air Force evaluation, conducted by the Aerospace Technical Intelligence Center (ATIC), suggested the object was likely a satellite, noting that the 'wiggle' observed at the end of the flight path could be attributed to atmospheric phenomena. The document includes a memorandum dated January 23, 1961, from Colonel Philip G. Evans to L/Col Tacker, confirming that the sighting report had been forwarded to 'Space Track' for correlation with known satellite data. The results of this correlation were negative at the time of the memo, and the office was awaiting further information. The correspondence highlights the standard procedure for investigating aerial phenomena during this period, specifically the attempt to rule out known orbital objects before classifying the sighting.
