Fast UFO over Colorado in 1957

Summary

In January 1957, a witness in Longmont, Colorado observed an object moving extremely fast northward with a short orange flame trailing behind. The report classifies the observation as probably astronomical, suggesting it could have been a meteor. Although no photos or radar were used, the civilian testimony describes a brief but clear experience. The exact duration of the sighting was not recorded, but the object was seen only once.

The report includes comments indicating that the brief description points to a natural explanation, such as a meteor. However, the speed and trajectory of the object generated some uncertainty, leading to the consideration of an aircraft as well. Despite the doubts, investigators concluded it was likely an astronomical phenomenon. The document is part of a historical file of UFO sightings attempting to make sense of unexplained aerial phenomena.
