Project 10073 Record Cards - Dayton, Ohio, October 1963

This document contains a series of Project 10073 Record Cards and associated technical information questionnaires documenting multiple sightings of unidentified aerial phenomena in the Dayton, Ohio area during October 1963. The reports detail various observations made by civilians. The first major incident, reported on October 3, 1963, involved an object described as a 'twisted flame' about the size of an aircraft, yellow in color, with red and green lights. The object was observed moving north and maneuvering. Subsequent investigation revealed this to be a Tri Pacer aircraft (tail number #6LX) towing an electrical advertising banner reading 'Gem City'. Other reports in the file include a flash of light on October 6, 1963, which was determined to be a meteor; observations of a bright object in the east between October 8 and 10, 1963, identified as the planet Jupiter; and a report on October 10, 1963, of an object moving through the sky, which was identified as the ECHO I satellite. The documentation includes handwritten notes from witnesses, sketches of the objects' paths, and technical data sheets regarding the visibility of the ECHO I satellite over Dayton during that period. The files reflect the standard procedure of the Aerial Phenomena Branch to collect civilian reports and cross-reference them with known astronomical, meteorological, and aviation data to provide conventional explanations.
