Project 10073 Record — Sioux City, Iowa, 17 April 1966

This document consists of a Project 10073 record and an associated incoming Air Force staff message regarding a UFO sighting in Sioux City, Iowa, on 17 April 1966. A single witness, identified as a housewife whose reliability was marked as unknown, reported observing an oval-shaped object for three to five minutes. The object was described as orange in color with a 'white shadow' near it. While the object itself was reported as motionless, the witness claimed the white shadow was moving. The sighting occurred at night under broken cloud cover. The official conclusion reached by the investigating officer, 1st Lt. John J. Konrad of the 30th Air Division, was that the object was an astronomical phenomenon, specifically a star seen through the broken clouds. The report includes internal commentary questioning the nature of the 'white shadow' and expressing skepticism regarding the quality of the report, which was explicitly labeled as 'very poor'.
