PARIS, ILLINOIS - 9 October 1951

On 9 October 1951, at approximately 1345 CST, a private pilot en route from Greencastle, Indiana, to Paris, Illinois, sighted a silver object just east of Paris, Illinois, at 5,000 ft. altitude. The object appeared to be stationary in as much as it did not increase or diminish in size with the approach of the aircraft. The object then started to travel in a north-easterly direction south of the Newport, Indiana, Atomic Energy Plant.

(See Appendix VIII for related incident.)

Weather

Clear, bright sun, no clouds or haze.

Status of investigation

More details of the incident will be obtained. Weather balloons are launched from Chanute AFB which is approximately 45 miles NW of the location of the incident. It is very doubtful if this object was a balloon as the balloon would have risen to a much higher altitude if it had drifted SE from Chanute AFB.
