UFO Observation Report — California Zephyr, Colorado, June 1967

This document contains a series of reports and correspondence regarding a UFO sighting reported by a 13-year-old passenger on the California Zephyr train in Colorado on June 18, 1967. The witness, a civilian, observed three dull white objects while traveling through the mountains and took photographs of them. The witness described the objects as moving slowly and noted that they did not appear to be related to anything outside the train. The Air Force requested the original negatives and a completed photographic data sheet for scientific investigation. A subsequent photo analysis report, dated November 30, 1967, concluded that the images were likely photographic phenomena. The analysts determined that the curvature of the train's observation window caused reflections of objects inside the car to appear in the photographs. Because the camera used was a fixed-focus Kodak Instamatic 100, the images were slightly out of focus, which the analysts attributed to the objects being closer to the camera than six feet. The report concluded that the images were stationary relative to the camera and window and were not related to any external aerial phenomena.
