UFO sighted at Buckley, Colorado in 1964

Summary

In July 1964, an observer in Buckley, Colorado, reported a bright object moving at high altitude. He described the object as resembling a magnesium flare, moving from west to east before disappearing about 10 feet above the end of the runway. According to the report, it appeared as if pieces of burning metal were falling off the object. The witness, Ronald Horn, a dispatcher deemed reliable, observed the phenomenon for two minutes. Although initially considered as a possible rocket or balloon, investigators concluded it might be a "particulate flare," meaning a spark or flash caused by particles in the air.

The report, classified under Project 10073, was reviewed by military officials and no conventional explanations were found. There were no adverse weather conditions or alerts at the time of the sighting, suggesting the testimony is credible. Despite the detailed description, no photos or radar records were taken, limiting physical evidence. The responsible officer, Hirschoff, considered the possibility of an atmospheric phenomenon, but no definitive conclusion was reached. This case remains one of many unresolved sightings from the era.
