Project 10073 Record Card and Related Correspondence — 12 September 1964

This document consists of a Project 10073 Record Card and several associated military cables documenting a series of aerial sightings that occurred on 12 September 1964 in the vicinity of Mountain View and Castle Air Force Base, California. The record card summarizes three distinct observations: an orange-red round object with a trail of light seen for three seconds; a yellow light resembling a comet tail, described as the size of a nickel held at arm's length, observed for ten seconds; and a round white object with a tail similar to a falling star that blinked out after five seconds. The official conclusion recorded on the card is that these events were meteor observations. The accompanying military cables, dated 1955 and 1964, provide further administrative context, including compliance with Air Force Regulation 200-2 regarding the reporting of Unidentified Aerial Phenomena. One cable details a sighting from 12 August 1954, describing a round, white object with a tail similar to a falling star, observed by a Technical Sergeant from the 93rd Air Base Group, who was noted as being fairly reliable. The cables confirm that these sightings were not corroborated by other sources and were generally attributed to astronomical phenomena such as falling stars or meteors, with no known aircraft in the vicinity.
