Narrative

On 1 June 1955 at 1718Z, a civilian in Harrisburg, Pennsylvania reported observing a round silver sphere the size of a basketball that appeared to land on railroad tracks before disappearing. Observed by ground visual with binoculars. The intelligence officer noted that twelve other witnesses present at the time denied observing any objects, leading to evaluation as probable optical illusion.
