Mystery Boom in Georgia

Mystery boom still confounding officials

This sound would fall into the category of strange phenomena called brontides that Charles Fort had an interest in.  That this mystery boom was a brontide seems like a simple enough explanation but there is also the possibility that it was a top secret aircraft like the Aurora performing a test run.  If it is a secret aircraft then the owners will most likely never admit responsibility for the boom.

Personally, I have no idea what it could have been.  The more probable explanation is that it was a supersonic aircraft of some kind, but it would have to have been a secret craft as flying at high speed isn't permitted over that part of Georgia.  It could have been an extraterrestrial craft for all we know.  Until the experts can determine some mundane cause for the sound we're left to wonder.
