White UFO seen in Arizona in 1960

Summary

A man in Glendale, Arizona, observed a white, round object the size of a quarter. The object crossed the path of a "dust devil" and moved in a straight line at high speed. The witness, who wore glasses, did not use optical aids and claimed it wasn't an object picked up by the wind. Weather conditions showed a strong thermal inversion, which could explain optical phenomena. Despite the brief observation (15 seconds), the report concluded that the data was insufficient for a definitive evaluation.

The thermal inversion recorded in the area could have caused refractions or mirages, complicating the object's identification. There was no physical evidence or radar records confirming the object's presence. The witness, although cooperative and detailed, couldn't be rated as particularly reliable. Explanations like meteors, satellites, or balloons were ruled out, but the object's nature remained undetermined.
