Notable Colorado UFO sightings uncovered in Project Blue Book

📍 Location

📝 Description

Publicly available Project Blue Book materials reveal five notable Colorado UFO sightings from 1947–1956. These cases are documented in declassified Air Force files and summarized in media coverage (notably a 2016 Denver7 piece). No new official confirmations have been released for these specific Colorado cases since the archives went online; details rely on the Blue Book records and secondary summaries. The cases vary in witness type and description, from a seven-person railway crew sighting near Manitou Springs to a daylight sighting by a state senator in La Veta, and include the Denver metro area and Pueblo vicinity. Collectively they illustrate the era’s pattern of unidentified objects reported to Project Blue Book without a conclusive public explanation.

🔍 Circumstances

Pikes Peak region (Manitou Springs area), May 19, 1947: seven Pikes Peak Railway employees observed a bright, silver/metallic object overhead that performed erratic gyrations for several minutes; authorities estimated a notable altitude, with the incident later associated with the era’s ‘supersonic platters’ discussions in Blue Book records. Southwest Denver vicinity (Lowry AFB area), Aug 20, 1949: a flight instructor (Theodore Mahoney) observed a flying disk moving at high speed and not matching known aircraft; object described as oval-shaped and not identified. Edgewater, near Denver, Aug 21, 1954: a Aurora-area witness saw up to 12 flying saucers at the Lakeshore Drive-In; about 15 minutes later additional objects were seen moving toward Stapleton; duration not specified. La Veta, Nov 25, 1955: State Senator S. T. Taylor reported a daylight sighting of a barrel-shaped, luminous green-blue, jelly-like object that dove and then altered its angle, seen for about 5 seconds. Near Pueblo, Dec 1, 1956: a couple observed a white cigarette-shaped object with a glow atop and a vapor trail, moving slowly and disappearing near Mt. Baldy; duration not specified.
