Diamond-shaped UFO seen in Kansas

Summary

In August 1965, a witness in Kansas observed a diamond or delta-shaped object moving from south to north. The sighting lasted about 15 seconds and the object left a bright green tail. The report classifies the event as "Astro" (possibly astronomical), though other explanations are not ruled out. The witness, a salesman, claimed the object seemed to "flame out," adding mystery to the case.

The official report does not include photos or physical evidence, and the analysis concludes that no definitive cause can be determined with the available data. The document, part of Project 10073, was processed by the U.S. Air Force, but no conclusive explanation was reached. This case, though brief, remains one of many that raise questions about the nature of unidentified objects.
