Source of loud noise, shaking in Central Illinois identified

At around 11:20 a.m. on Tuesday, Dec. 21, the Illinois Emergency Management Agency was made aware of a large noise and shaking felt by many residents throughout central Illinois.

This loud boom kicked off an immediate collaboration between federal, state and local officials to identify the impact and source of the incident. 
Upon further review, it was determined that an F-15 fighter jet in the airspace above central Illinois course corrected creating a sonic boom. When the aircraft broke the sound barrier, the pressure wave created an audible noise and minor shaking that could be heard and felt throughout multiple counties in the region. 
At this time there are no reports of damage associated with the incident.
