Circular UFO over Pittsburgh Airport

Summary

In April 1957, a witness in Coraopolis, Pennsylvania, reported a circular object with red and blue lights above Pittsburgh Airport. The report details that the object was about 150 feet in the air and was not seen by other aircraft, control towers, or people in the area. Despite the observer's extensive experience with military and civilian aircraft, they insisted the object was not conventional. The lack of confirmation from other sources raised concerns about potential rumors or negative publicity.

The case was classified as confidential, and further investigation was ordered to prevent more reports or calls. It was noted that the object was not detected by radar or other aircraft, adding to the mystery. The final report did not reach a clear conclusion, but it considered the object could have been a balloon, an astronomical phenomenon, or even an optical illusion. However, the observer insisted the object was close and low, making a conventional explanation difficult.
