Project 10073 Record — Cheyenne, Wyoming, September 1965

This document is a record from the 809th Strategic Missile Wing (SAC) regarding a series of Unidentified Flying Object (UFO) sightings reported in the vicinity of Cheyenne, Wyoming, and surrounding areas in August and September 1965. The report, dated 20 September 1965, serves as an addendum to a previous report from 6 August 1965. It details several distinct sightings involving military and civilian witnesses. One incident involved a civilian guard at the Sioux Army Depot observing an object with binoculars, while another involved nine military personnel at a Hotel Launch facility. A third report came from a Geodetic Survey Team using a theodolite, and a fourth from a group of eight civilians using a 50/100 telescope. The objects were described variously as having up-and-down motion, emitting white, red, green, or blue lights, and in one instance, producing a roaring jet-like noise. Some sightings were attributed to weather balloons or the planet Jupiter. However, the overall conclusion for the specific record (Project 10073) was that there was insufficient data for a definitive evaluation. The report includes maps plotting the locations of the sightings relative to missile launch control centers. Major Elva D. Brown, an Intelligence Staff Officer, compiled the report, noting that the Geodetic Survey personnel were well-trained in astronomy and provided accurate descriptions.
