Bright UFO Sighted Near Benson in 1957

Summary

A group of civilians in Arizona observed a bright object in October 1957 while searching for the Sputnik I satellite. The object suddenly appeared on the southeast horizon, emitted a yellowish light, and quickly moved across the sky toward the northwest, disappearing minutes later. Although initially thought to be the Russian satellite, its trajectory and brightness didn't match expectations. Three photographs captured the event, clearly showing an object distinct from airplanes or stars. Researchers considered the possibility of artificial meteors, as such experiments were conducted around that time, but no definitive identification was made.

Calculations suggested the object was at least 35 miles high, ruling out common atmospheric phenomena. Despite later analyses, the mystery remained, and the report was shared with scientific and military institutions for evaluation. The coincidence with artificial meteor experiments and the lack of a conventional explanation kept the case in a limbo between the ordinary and the unexplained.
