UFO seen in Colfax Iowa in 1956

Summary

In November 1956, a witness in Colfax, Iowa, observed a round reddish-yellow object about the size of a basketball. The object tapered to a point and moved from southeast to northwest, disappearing behind the horizon. The observation lasted one minute and was recorded in an official report. Although other explanations such as balloons or astronomical phenomena were initially considered, investigators concluded it was likely an aircraft. The description, trajectory, and manner of disappearance supported this interpretation.
