Project 10073 Record: Sighting in Lakewood, Colorado, 11 December 1966

On December 11, 1966, at 2145Z, a civilian witness in Lakewood, Colorado, observed a single unidentified object for approximately 30 minutes. The witness, an electronics technician at Fort Logan Hospital, reported that the object was initially round and about the size of a grapefruit held at arm's length, but later appeared to be shaped like an obelisk with a hyperbole angle. The object's color shifted from gold to pink. The witness noted that the object moved slowly toward the western sky with no apparent motion other than a sideways movement, eventually disappearing in a straight upward motion. The observer first noticed the object while parked in an automobile, noting it appeared to hover and move side-to-side after emerging from clouds over the mountains west of Lakewood. The weather was reported as clear with no wind. Major Edward E. Vigee of the Technical Air Training Center (ATC) at Lowry Air Force Base evaluated the report. He noted that while there were numerous aircraft in the area west of Denver, the duration of the sighting made an aircraft identification unlikely. The official conclusion reached by the project was that the object was possibly a balloon. Major Vigee further remarked that the individual likely saw military aircraft in the area, noting that three years prior, a similar sighting in the same area had been described as appearing like a harp.
