Blue UFO with white trail in Colorado Springs

Summary

A 1967 report describes a UFO observed for nearly two hours in Colorado Springs, Colorado. The witness, a 44-year-old woman, saw a bright object with an extremely blue color and a white vapor trail moving slowly northeast. The object was brighter than any star and had fuzzy edges. It was estimated to be about 8 degrees above the horizon, and its size was roughly the size of the first joint of a thumb. No noise was heard, and the object passed in front of a star, suggesting controlled movement. The report includes sketches from the witness showing the object's path.
