Project 10073 Record — Indian Hills, Colorado, 4 June 1967

On 4 June 1967, a civilian reported a UFO sighting in Indian Hills, Colorado. The observation lasted approximately 20 minutes. The witness described a single, round object that appeared as a silver dollar held at arm's length, which later changed to a small orange color and then a blue-ish white, casting a reflection on the nearby mountains. The object was observed at an altitude of approximately 9,000 to 12,000 feet, moving slowly from south to north with a gradual descent toward the horizon. The object was noted to dim and then brighten to a 'very bright' state. At the time of the report, the object was still visible. The weather was reported as clear with 20 miles of visibility and scattered clouds at 12,000 feet. The Air Force, specifically the Foreign Technology Division, processed the report under Project 10073. TSgt David E. Dosy, acting as the duty controller, concluded that there was insufficient data to evaluate the sighting. The Air Force subsequently sent a letter to the witness requesting they complete FTD Form 164 for further scientific evaluation.
