Project 10073 Record Card — Tucson, Arizona, 15 September 1960

This document contains records regarding a sighting of unidentified aerial phenomena reported on September 15, 1960, in Tucson, Arizona. The primary report is a Project 10073 record card detailing an observation made by a civilian machinist. The witness reported seeing approximately 20 round, bright orange objects, described as being slightly smaller than a grapefruit and football-shaped. These objects were observed in a formation that moved from the east, executed a 90-degree turn, and proceeded toward the south-southeast before fading from view. The observation lasted between 10 and 20 seconds. The witness reported no sound, no exhaust, and no tail associated with the objects. The investigating officer, based at the 684 ACW Squadron at Mt. Lemmon AFS, noted that the witness appeared sincere during a telephone conversation. However, the investigation concluded that there was insufficient data available for a formal analysis. The report highlights that the objects were not detected on radar and no physical evidence was recovered. The investigator noted that if the sighting were authentic, it would be expected that more than one person would have observed the objects. The document also includes a teletype report sent to the Air Technical Intelligence Center at WPAFB, which reiterates the details of the sighting. Additionally, the file contains a separate, brief mention of a cylindrical, glowing orange UFO sighted on September 14, 1960, in the Caribbean Sea by the captain and two officers of the American S.S. Orion Clipper. The primary Tucson case was ultimately categorized as having insufficient data for evaluation, with a speculative note suggesting a possible connection to a 'moon dust alert'.
