Fighter Wing Flight Broke Speed of Sound in Southeastern Wisconsin

Last night residents and National Weather Service noticed the ground shaking. 

The National Weather Service at first reported it may have been a frost quake. However, later noted that there was military exercises going on in the area. 

A 115th Fighter Wing F-16 Fighting Falcon unintentionally exceeded the speed of sound during routine night training in the airspace above south central and south eastern Wisconsin Jan. 12, at approximately 8:29 PM, according to the 115th Fighter Wing Public Affairs Office. 

The jet's speed, which caused the air to compress, resulted in a sonic boom heard by numerous Wisconsin residents.

"The 115 FW pilots make every effort to minimize the impact of their training missions to local residents," said Capt Boustany.
