Surprisingly this was neither listed
among the original BB Unknowns, nor the updated Comprehensive Catalog
of Project Blue Book Unknowns by Brad Sparks. It wasn't on our site and
wasn't listed among the 200 nuclear connection cases by Larry Hatch
(NCP-03). The Air Force documents were found originally by Dan Wilson
on the BB Archive site and I matched it up with the report by Bruce
Maccabee. I then located the AFOSI documents in my files and
scanned them
in. (See report and document links below). The documents clearly show
radar had detected UFOs at the same time.
NARA-PBB90-638: "At about 1520 EST 16
October, while Special Agent William S. Price was present, a report
came from the AEC Patrol to the radar station relating that a Trooper
Isabell and four civilian employees at Oak Sidge had observed a "silver
disc" hovering over the K-25 Plant in the controlled area. The radar
screen was able to pick up an indistinct target about every three (3)
or four (4) sweeps of the indicator. An F-82 fighter plane was sent to
attempt an intercept of the object. The airborne radar of the fighter
picked up a target which later proved to be a light aircraft. The
ground observers reported that the F-82 passed under the "silver disc"
while it was in pursuit of the light plane. The crew of the fighter
observed nothing unusual. Nothing further was learned of the sightings."
