Francis Ridge:
Not listed in either BB Unknown list, original or Comprehensive Catalog of Blue Book Unknowns , but has aspects that may ultimately classify it as an unknown. At 4:55 PM on October 20, Larry Riordan, the Superintendent of Security for the X-10 control zone became a witness.  While driving to a residential area he saw an object which he thought at first was a balloon which had lost its “basket.”   It was generally round, appeared to “come together at the bottom in wrinkles (rather indistinct and something was hanging below.”   It appeared to be 8 to 10 feet long and lead or gunmetal colored.  It didn’t seem to be moving but, since he was traveling and only saw it for a number of seconds, he couldn’t be sure.  He was sure it wasn’t a weather balloon, although he thought it might have been a gas bag balloon launched by the nearby University of Tennessee Agricultural Research Farm..  On the same day at 3:27 PM the radar unit at the Knoxville airport detected radar targets near the area of Mr. Riordan’s sighting and scrambled a fighter plane.  The pilot searched the area for about an hour and a half, which included the time of Mr. Riordan’s sighting, and found nothing.

Brad Sparks:
The Riordan sighting might be a balloon, but we won't know until AF data can fill in more details.
