UPDATE: We now know what that mysterious 'boom' in west Michigan was
From WOOD TV:
Kent County dispatchers said they also handled dozens of calls about the loud explosion-type sound.
Facebook exploded as well, with numerous posts to the WOOD TV8 page. “Felt like a bomb going off,” was a common comment.
A day and a half later, we still don’t know what it was, but we do know what it wasn’t.
Forecasters at the National Weather Service in Grand Rapids said Monday there was nothing within 100 miles weather related that would have caused the noise.
Anyone who may have any idea or information on what this was is asked to contact the Kent County Sheriff's Department at 616-632-6100.
