© abc3340.comA loud boom was heard over much of north Alabama on November 14, 2017
It's the sound everybody is talking about. So much so, Trey Cochran wrote a song about it:
Alabamians flocked to Twitter, with many reporting the event shook their homes.
Lincoln resident Dawn Stanton described it as "...a propane tank just exploding. I looked and I didn't see nothin' sailing through the air."
The National Weather Service in Birmingham hypothesized the sound originated from an aircraft sonic boom or a meteorite from the Leonid shower.
NASA's Bill Cooke says the origin of the mysterious boom still remains unclear but shut down the NWS' theory of a Leonid shower meteroite.
Cooke says the sound could have been produced by a bolide, large supersonic aircraft or a ground explosion.
According to Cooke, NASA's meteor scientists will continue to analyze new data in hopes of determining the cause of the 'boom.'
ABC 33/40 has reached out to Maxwell Air Force Base to see if a pilot could have broken the sound barrier with a training exercise.
