Denver UFO Report 1958

Summary

In August 1958, a Denver, Colorado, civilian reported observing three reddish-orange objects, each about the size of a baseball. The objects moved in an almost straight line and slowly disappeared behind trees. The official report under Project 10073 concluded that there was insufficient data to evaluate the sighting. Although Spica and Jupiter were mentioned as possible astronomical references, they did not align with the exact location of the objects. The witness, a reliable businessman in his 40s, described the event in detail, but no photographs or radar data were available. The Air Force noted the possibility of an unidentified aerial phenomenon but could not confirm any specific explanation.

This case occurred during a period of heightened public interest in UFOs, with numerous sightings reported across the U.S. Most were attributed to natural phenomena or known objects like balloons or reflections, but some remained unexplained. The lack of photographic or radar evidence limited the investigation, yet the detailed visual account and the unusual behavior of the objects sparked some curiosity among researchers at the time.
