UFO seen in Longmont in 1966

Summary

In October 1966, a citizen from Longmont, Colorado, reported an unidentified flying object that remained visible for about 15 to 28 minutes. The initial report contained inconsistencies in the sighting date, prompting a request for clarification. The object was observed at an altitude of approximately 2.64 degrees above the horizon and was described as stationary. Despite investigations, no conventional explanation, such as satellites or aircraft, was found to account for the phenomenon. The case was handled by Project Blue Book, which requested additional information from the witness for a more accurate evaluation.

The report included testimonies from ground and airborne observers, but no physical evidence or conventional explanations were found. The object showed no changes in appearance and did not emit noise, adding to the mystery of the sighting. Although local agencies were contacted, no further information was obtained. The case was closed without a clear resolution, highlighting the difficulty Project Blue Book faced in identifying non-conventional objects.
