Project 10073 Record Card — Sloan, Iowa, 18 October 1955

This document is a Project 10073 record card and associated teletype report concerning an Unidentified Aerial Phenomena (UAP) sighting that occurred on October 18, 1955, near Sloan, Iowa. The witness, a 35-year-old clergyman, reported observing four objects for a duration of four minutes. The objects were described as oblong, white, and approximately four to five feet in length. Two of the objects were observed at a high altitude, while two were observed at a lower altitude. The witness reported that the objects moved from the northeast to the southwest and were accompanied by a slight sound as they moved into the sun. The report was processed by the 789th AC&W Squadron in Omaha, Nebraska, and transmitted to various Air Defense Command (ADC) and Air Technical Intelligence Center (ATIC) units. The official conclusion reached by the evaluating authorities was that the sighting was likely caused by aircraft activity in the vicinity at the time of the observation, noting the color, sound, and the presence of T-33 aircraft on penetration runs at Sioux City as contributing factors to this assessment.
