Project 10073 Record Card and Investigation Correspondence — Manitowoc, Wisconsin, April 1958

This document details a UFO sighting investigation conducted by the Air Technical Intelligence Center (ATIC) and the 1006th Air Intelligence Service Squadron regarding an incident on April 12, 1958, in Manitowoc, Wisconsin. Two nuns at the Holy Family Convent reported observing two unidentified flying objects. The witnesses described the objects as red, circular, and grapefruit-sized, exhibiting erratic movements including hovering, bouncing, and changing colors. The witnesses were interviewed by the local Civil Air Patrol and later by Air Force personnel. The investigation was handled with sensitivity due to the witnesses' reluctance to face public scrutiny and the Air Force's concern that the incident might be exploited by 'flying saucer' proponents. Major Ralph N. Albright of Detachment 7, 1006th AISS, conducted the interviews and compiled the data. The official conclusion reached by the Air Force was that the sightings were misidentifications of the stars Betelgeuse and Pollux, with apparent movement and color changes attributed to atmospheric conditions and potential confusion with surface lights. The file includes the original Project 10073 record card, official correspondence between ATIC and the 1006th AISS, transcripts of interviews with the witnesses, and technical information sheets completed by the observers.
