On 16 Jul 2003 I received this note
from Jan Aldrich:
Excerpt from "Historical Data of 30th Air Division (Defense), Eastern
Air Defense Force, Selfridge Air Force Base, Michigan for October to
December 1951, page 32 under the "Unusual Flying Objects:"
"A civilian guard (AESS) on duty at Oak
Ridge, Tennessee reported
sighting an
airborne object on 7 December 1951 at 0815 EST. Traveling at a
constant speed, equivalent to conventional aircraft, the object was
described as square, approximately 20 feet wide, grey-white in color,
with no markings. The observer, age 40, is described by his employer as
honest and conscientious, and is held in high respect by his
employer. Two F-47's were unsuccessful in an attempt at
interception."
The report is still listed as Unknown # 1021 by Project Blue Book and
carried
the same in the updated Comprehensive Catalog of Project Blue Book
Unknowns by Brad Sparks. On 20 May 2005 Dan Wilson filed his report on
the documents below from the BB Microfilm site.
