UFO seen during Minuteman missile launch in Oregon

Summary

A 1965 report describes the observation of a glowing balloon-shaped object with a tail over Oregon, coinciding with a missile launch. Three witnesses, including an air traffic controller, saw a white-green object that vaporized and left a contrail. The description suggests a connection to the Minuteman missile launch from Vandenberg AFB. Although normal conditions were reported, the document mentions an "unusual visual phenomenon" linked to the event. The official report classifies it as atmospheric, but details align with the missile launch.
