Red UFO seen over Philadelphia in 1966

Summary

In 1966, a witness in Philadelphia, Pennsylvania, reported a red, circular object moving northward. The report, part of the U.S. Air Force Project 10073, briefly describes a phenomenon that caught attention for its appearance resembling an airplane's red light, though no other visual indicators were present. The object disappeared behind a building and made no sound. Although the observer described it as a red light, its nature could not be definitively determined due to a lack of additional data or physical evidence.

The Air Force concluded the object was not a conventional aircraft, but no definitive explanation was reached. The report includes detailed questions about the event, though many sections remain incomplete or ambiguously answered. This document reflects the investigative approach of the time, where testimonies were collected to analyze unidentified phenomena. Despite the brief sighting, the case remains an example of how UFO reports were recorded in the 1960s.
