This Project Blue Book case file covers the 7 January 1948 incident at Godman Field, Fort Knox, Kentucky, which the file itself calls the famous "Mantell case." It holds control tower witness statements describing a large, bright object and the three P-51s sent to pursue it, whose flight leader, Mantell, stopped answering after climbing past 15,000 feet. It also includes weather data and Air Materiel Command correspondence. One analysis concludes that the object was not Venus and that the sighting must be considered unexplained.

STATEMENT OF LT PAUL I ORNER Following is an account of the sighting of unknown objects from the Control Tower on 7 January 1948 at Godman Field: On the above date at approximately 1400 CST a report came in to the Control Tower through M Sgt Cook of a report of an unidentified object flying at terrific speed in the vicinity of Maysville. This call was canceled minutes later by the Military Police at Fort Knox who had instructions from the Kentucky State Police. Very soon thereafter several reports of the same nature came from Flight Service saying this object was over Irvington and Owensboro, Kentucky. At the same time an object was reported by T Sgt Blackwell, Chief Control Tower operator on duty. I was in the office of the Commanding Officer checking the call from the Fort Knox Military Police at this time. When the call was cancelled I was returning to the Control Tower to see the object sighted by them. I immediately went to the Control Tower and saw a small white object in the southwest sky. This object appeared stationary. I was unable to tell if it was an object radiating its own light or giving off reflected light. Through binoculars it partially appeared as a parachute does with bright sun shining on the top of the silk but there also seemed to be some red light around the lower of it. The Commanding Officer, Operations Officer, S-2 and Executive Officer were called immediately. Several minutes after the object was sighted a flight of four (4) P-51's came over the field from the south. I instructed T Sgt Blackwell to call flight leader and ask if they had seen any evidence of this object. The flight leader answered negative and I suggested to the Operations Officer that we ask them if they had enough gas to go look for this object. The Tower operator was instructed to call the flight leader and he answered "yes" to this question. One (1) P-51 had permission from the flight leader to break formation and continue where he landed several minutes later on their original flight plan. The flight leader and two (2) other planes flew a course of 210° and in about five (5) minutes sighted the object. At first the flight leader reported it high and about one-half his speed at "12 o'clock". Shortly thereafter the flight leader reported it at about his speed and later said he was closing in to take a good look. This was the last message from NG869, the flight leader. NG800 shortly thereafter reported NG869 disappeared. From pilots reports in the formation NG869 was high and ahead of the wing man at about 1515 CST to 1530 CST when he disappeared. NG800 said he was breaking off with other wing man to return to Standiford Field due to lack of gas. This was about 1525 CST to 1530 CST. From messages transmitted by the formation it was estimated the flight leader was at 18 to 20 thousand feet and the wing man at approximately 15 thousand feet wide formation when the flight leader NG869 disappeared. NG800 and other wing man returned to Standiford Field. UNCLASSIFIED
