Unidentified Flying Objects (UFO) Report — Elizabeth, Colorado, December 1966

This report documents two separate sightings of unidentified aerial phenomena near Elizabeth, Colorado, in December 1966. The first incident occurred on December 18, 1966, when an observer sighted an object while driving on a highway six miles south of Elizabeth. The second incident occurred on December 22, 1966, involving a witness in the backyard of a home in Elizabeth. The objects were described as conical in shape, resembling a multi-storied building with a curved, domed bottom. Witnesses reported the objects as bluish, misty, and hazy, with one witness noting a yellowish-orange color. The objects were observed hovering at an estimated altitude of two to three thousand feet. Maneuvers included descending and then rapidly ascending straight up until they disappeared from sight. The objects featured blue lights on the bottom that appeared to blink in a controlled manner. No sound was reported during either sighting. The weather conditions were described as clear with no cloud cover. The investigating officer, Major Edward E. Vigee of the Lowry Technical Air Training Center, concluded that there was insufficient data for a formal evaluation. The only physical evidence provided was a drawing created by a 12-year-old boy who witnessed one of the events.
