Triangle UFO over Colorado Springs

Summary

A declassified report describes the observation of three round objects, 53 feet in diameter and 13 feet high, seen flying in a tail formation over Colorado Springs in 1952. Witnesses reported the objects were aluminum-colored with a reddish yellow exhaust, and no sound was heard. Their speed was estimated at 1533 mph, and the objects passed in front of the moon before suddenly disappearing. The report includes meteorological and astronomical data, but the phenomenon could not be identified with certainty. The lack of noise and unusual speed raised doubts about their conventional nature.
