UFO seen in Chicago Ridge in 1968

Summary

In April 1968, a witness in Chicago Ridge, Illinois, reported seeing an unidentified flying object with red lights on both sides that moved up and down, back and forth. The report, though incomplete, mentions that the sighting lasted 20 minutes and was visual. However, the observer did not provide further details, leading to the conclusion that there was insufficient data for evaluation. The Air Force requested the observer to complete a form for more information, but no additional responses were received. The case remains unsolved.
