Unidentified object observed in Evanston in 1963

Summary

In May 1963, a witness in Evanston, Illinois, reported an unidentified object that appeared in the sky and moved toward the northwest. The object, described as solid with lights and a low humming sound, was observed for three minutes. Its erratic movement initially suggested it might be a publicity dirigible. An expert, Dr. J. Allen Hynek, saw it with an electric light and confirmed it was not a plane or a common balloon. Although several possibilities were considered, no definitive conclusion was reached.

The technical report includes detailed questions about the observation, such as the exact location, time, and sky conditions. The witness provided key information, such as the duration of the sighting and the object's direction. Despite ruling out some common explanations like balloons or aircraft, the phenomenon remained unexplained. This case is part of the records from Project 10073, which collected data on unidentified flying objects for further analysis.
