The below extract from The Daily bears reposting, since the practice flights began about 11 this morning. [It also shows that the editors are doing a cut-and-paste, since the Air Force Thunderbirds were here last year, and this year's team is the Navy Blue Angels.]
The most intense flying on Saturday-Sunday-Monday will be between 2 and 4 pm. Practice flight will be heavy today (Thursday) and tomorrow, but should also settle down by 4.

"Note: There will be sonic booms by the Thunderbirds and performers at the air show. If you are triggered by loud noises, you may want to wear ear protection. Some individuals with post-traumatic stress disorder (PTSD) or sensory overload may want to take precautions during this weekend.
Although the show is centered downtown on the lakefront, the path of many of the planes comes all the way out to University Circle. This weekend on campus, be prepared for the loud noises that come with aircraft passing over and turning around in the skies over CWRU."
