Explanation:

Resource Used: Grammarly

I copied and pasted the original sentence into Grammarly. The first suggestion it gave me was to fix the spelling of "flyin(g)." Once I did this, there was one premium suggestion. The premium suggestion said the punction in compound/complex sentence(s) was an issue. Specifically, they underlined the name Milwaukee and the semicolon next to it. As you can see, you can notice the adjustments that Grammarly approved.

I hope this helps you in any shape or form.
