On 6 July 1947 while fling from Ogden, Utah, to Kansas City, Mo, at 10,000 ft in a B-25 pilot noticed a very bright object low and to his left, approximately 10 miles away. Time was 1:15 P. M. and position was approximately 100 miles west of Kansas City. His first impression was that it was the top of a water tank. After checking his position he again looked to his left (elapsed time 5 seconds). He saw a round, disc shaped object, very bright and silvery colored which seemed to be flying 1 to 2 miles off his left wing at 11 o'clock position at 11,000 ft. The brightness of the object was very great. Diameter of the object was estimated as 30-50 feet. It was traveling in the same direction at the same rate of speed (210 MPH) as the observer. However, when he started to turn into it, it completely disappeared. Weather conditions at the time were CATU.
