Narrative

At 0111Z on 20 May 1955, an observer in Oroville, California noticed a round silver object the apparent size of a silver dollar standing still in the sky. No flight path - it just stayed in place and then faded from sight. Duration five seconds. Weather CAVU. 28th Air Division Director of Intelligence concluded the sighting was probably the reflection of a high-flying plane. HQ concluded possibly balloon due to the very brief observation.
