UFO Sighting in Greensburg, Pennsylvania

Summary

A man from Greensburg, Pennsylvania, reported three sightings of a bright object in August 1965. The object, described as much brighter than Jupiter, appeared in the sky and moved from east to west, fading as it approached the horizon. The witness, a nuclear physicist and computer programmer, ruled out satellites, meteors, and conventional aircraft. His experience with radar and aviation allowed him to analyze the object's characteristics with precision. On one night, the object appeared directly overhead, moving at an estimated speed of 2 degrees per second, suggesting a trajectory similar to that of a retrograde satellite. However, no clear explanation was found, and the possibility of a captured natural satellite or an unidentified phenomenon was considered.
