U.S. Air Force Technical Information Questionnaire — Dayton, Ohio, September 1964

This document contains U.S. Air Force technical information questionnaires regarding two separate sightings of an unidentified aerial phenomenon reported by a civilian in Dayton, Ohio, in September 1964. The first report, dated 4 September 1964, describes an object observed for 45 minutes that appeared to have the same intensity as stars in the Big Dipper, changed color between blue, red, and yellow, and moved in an elliptical path to the North. The official conclusion for this incident was that the object was the star Arcturus. The second report, dated 6 September 1964, describes an object observed for 10 minutes that appeared as a pale blue-white light, similar in brightness to Venus. The witness reported that the object changed brightness and speed, moving from the Southeast to the Southwest, with an initial flight path from the Northwest to the Southeast. The official conclusion for the 6 September sighting was that the object was the ECHO II satellite. The document includes a list of ECHO II data points over Dayton, Ohio, between 2 September and 7 September 1964, documenting its position and movement. The reports were processed by the Aerial Phenomena Branch, with Marilyn H. Stancombe serving as the Secretary.
