A loud boom caused all kinds of concern in Springfield late Wednesday morning. Dispatchers took several calls after the noise this morning around 11:45 a.m. It’s still unclear what made the sound. Some of the early reports were possibly a car backfiring or a blown transformer. Calls were reported all over town. – KTTS
