On 2 Aug 48, at 7:50 P. M. Mrs. Saunders observed an unusual object in the sky. Her attention was directed toward it because some neighborhood children were looking toward the north. She called her husband, Charles Saunders, (Inc 154) to witness the phenomenon. The sky was cloudless and the light more than sufficient, without interference from the rays of the sun which were hidden by the buildings of the city. Object first appeared oblong in shape and was traveling from north to south at a slow, regular speed. at a height of a half mile. During the 15 minutes under observation the object traveled approx 7-1/2 miles. Although it did not change its course, it presented different appearances from time to time. From oblong to circular then to oblong. Object went thru this change three different times until observer lost sight of it. However, for the most part it presented a circular appearance. Outline very dark in contrast with the transparency of the center. Only when the shape appeared circular was observer aware of the center being a void. Once it hesitated momentarily, observer noticed a tail of smoke emanating from the rear, after which the object continued in a southerly direction. This tail of smoke was observed but once. The size appeared to be that of a small plane. It made no sound altho at one time observer thought she detected one. At approx 8:00 P. M. observer lost sight of the object just as it appeared to be changing direction from South to Southwest.
