Project Blue Book Record — Plaza, Colorado, 5 April 1967

This document is a formal Project Blue Book sighting report filed by Major Edward E. Vige of the Lowry Technical Air Training Center regarding an incident on April 5, 1967, in Plaza, Colorado. A civilian witness reported observing a single, round, reddish object for approximately five minutes. The witness described the object as pulsating regularly and noted that its color shifted from bright to dim. The object was initially observed at an estimated altitude of 12,000 to 15,000 feet, where it hovered for 45 seconds before moving in a straight, level flight path toward the mountains, eventually disappearing. The report confirms that no photographs or physical evidence were collected, and radar contact was not established by Buckley Tower. The official conclusion reached by the Air Force was that the object was the planet Venus, which was setting at the time of the observation.
