The U.S. Air Force Thunderbirds will be flying high across Chicago's lakefront on August 15th and 16th.
The U.S. Navy Blue Angels usually alternate years with the Thunderbirds at the Air and Water Show, but will not this year due to a scheduling issue.
During the Thunderbirds' practice session last year, some Chicago lakefront residents described hearing sonic booms, but the Air Force denied that any jet went supersonic.
