Project 10073 Record — UFO Observation, 28 July 1968, Iowa City, Iowa

This document contains the Project Blue Book record for a UFO sighting reported in Iowa City, Iowa, on July 28, 1968. The primary witness, a staff member at the University of Iowa with a background in history and prior flight training, observed a bright white light traveling toward the WSW for approximately one minute and forty seconds. The witness explicitly stated that the object did not resemble conventional aircraft, satellites, or meteors, noting that it was self-luminous, silent, and maintained a steady, straight path without blinking or pulsating. The witness provided detailed responses to the Air Force's 'Sighting of Unidentified Phenomena Questionnaire' (AFR 80-17), including sketches of the object's path and its appearance relative to the horizon. The Air Force, specifically the Aerial Phenomena Office under Lt. Colonel Hector Quintanilla, Jr., initially requested more information from the witness, noting that the initial report was insufficient for scientific investigation. The final conclusion recorded on the Project 10073 record form is 'Possible (AIRCRAFT)'. The file includes correspondence between the witness and the Air Force, as well as surface observation data for the date of the sighting.
