Brown, Acting Chief, Review and Analysis Section, AEC, has been received from the Senior Instructor, USAR Instructor Group, Oak Ridge, Tennessee, and is transmitted herewith in accordance with directive cited in paragraph 1, above: "At approximately 3:00 P.M. on July 19, 1953, an F-86 aircraft was observed flying over the Oak Ridge residential area, making circles at what appeared to the writer to be approximately 2,500 or 3,500 feet. The F-86 flew over the area in this manner for approximately ten or fifteen minutes. The writer, together with his wife, observed the aircraft through a pair of six power field glasses. After the aircraft flew in what appeared to be the direction of Knoxville, Tennessee, a black object moved out of a high white cloud, directly over the area the F-86 had been flying. This object began to travel, at a tremendous speed, in a large circle. This action on the part of the unknown object continued for at least five minutes. During the circle of this object, it appeared at times to be in the shape of a cigar and at other times round." "This object was extremely black in color, having an appearance of a deep black metal exterior with a fine gloss. It did not leave a vapor trail or were there any lights of shine noticed. No sound was heard. The object flew east at a tremendous speed for what appeared to be approximately three miles where it stopped. The object was then joined by two more of these same objects. A formation similar to a spread "V" was formed and the objects, at a tremendous speed flew in an eastward direction." 3. Further information will be reported as received.
