## RESTRICT At approximately 1320 Sgt Cook from the CO's office notified the observer (T/Sgt Quinton A Blackwell) that according to Ft Know Military Police & "B" Town State Police, a large circular object about 250 to 300 ft in diameter was over Mansville, Ky. Advised him to check with Army Flight Svc. They advised negative but shortly thereafter reported object over Irvington, Ky, then Owensboro, Ky. Object first sighted by Blackwell about 1345 to 1350 over south Godman Fld. ## Verification: 1st Lt Orner (Detachment Commander) Capt Carter (Operations Officer) Col Hix (CO) sighted it about 1420 At approximately 11430 to 11440, four P-51's approached Godman f/south enroute f/Marietta, Ga. to Standiford Fld, Ky. Blackwell asked Flight Leader NG 869 to attempt to identify object. Accompanied by two other planes he proceeded south f/Godman. Fourth plane proceeded to Standiford Fld alone. About 11445, flight leader (NG 869) reported sighting object "ahead and above - still climbing" At 15,000 ft he reported "Object directly ahead and above and moving about half my speed." Again "it appears metallic of tremendous size." Still later "I'm still climbing - object is above and ahead moving about my speed or faster - I'm trying to close in for better look". This was about 1515. Five minutes later the other two ships turned back. NG 800 reported "it appeared like the reflection of sunlight on an airplane canopy" Shortly afterward this same pilot (NG 800) resumed search going to 33,000 ft, 100 miles south but did not sight anything.
