U.S. Air Force Technical Information Sheet — Sighting Report, Cincinnati, Ohio, 24 June 1953

This document is a U.S. Air Force Technical Information Sheet detailing a sighting report from 24 June 1953 in Cincinnati, Ohio. The witness, a 28-year-old value designer with some aviation cadet training, reported observing a single, spherical object while sitting on his front porch at 3308 Cavanaugh Avenue. The witness described the object as moving from north to south before executing a 90-degree turn to the east. Throughout the 15-second observation, the object reportedly pulsed yellow, orange, and red at a rate of approximately 120 pulsations per minute. The witness noted that the object crossed the face of the moon and appeared to have a darker edge encircling it. He explicitly stated that the object made no sound, left no trail, and did not resemble a shooting star or meteor, as it did not angle toward the earth. The witness estimated the object's size to be between 15 and 30 feet in diameter and its speed between 400 and 1,500 miles per hour at an altitude of 10,000 feet. He also mentioned a previous sighting in the summer of 1947. The official conclusion provided on the form is 'Astronomical (METEOR)', citing that local newspapers reported many people observed a meteor over the city on that date. The witness expressed skepticism regarding the meteor explanation, suggesting the object could potentially be an interplanetary craft, though he admitted he had no definitive idea of its nature.
