Not listed in neither the BB Unknowns
nor the updated catalog by Brad Sparks, this incident was mentioned in
the MUFON UFO Journal, Issue No. 205. An Army document was
located and is presented by the link below with a transcript. Briefly,
the incident is described here:
"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."
