ATLANTA (AP) -- Authorities west of Atlanta are trying to figure
out what caused a spectacular boom that rattled windows and
prompted 911 calls.
Residents of Carroll, Douglas and Haralson counties heard the
boom around 9:45 p.m. Friday.
Authorities say that no one who called 911 reported any emergency or explosion and no utility companies reported trouble.
One theory that surfaced Saturday was that it might have been a
sonic boom -- a large shock wave created by an airplane that goes
faster than the speed of sound -- seems unlikely.
Kathleen Bergen, a spokeswoman for the Federal Aviation Administration says no civilian plane can reach that speed.
She says there were no logs of military flights in the area around the
time of the boom Friday night.
