During their lunch period (1215-1315) 19 May 1947 a member of a train crew called attention to a silver object in the sky approaching from the Northeast. It appeared to be traveling at great speed. The object appeared extremely small and therefore the altitude could not be estimated. It did appear higher than the top of Manitou Mountain which is some 1,000 feet higher than the city. No definite shape could be determined even with the aid of power binoculars. The men were certain that the object was not a conventional aircraft since it did not have any of the physical characteristics. Upon reaching the area just north of Manitou the object remained in the area for several minutes during which time it executed maneuvers such as climbing, diving and reversal of flight. This happened every few seconds. The distance and location between views prompted two of the men to think that there may have been more of the objects in the sky. At times it seemed to hoever and then it would start on another flight path. When last seen the silver object was climbing very fast towards the west almost directly into the wind.
