Scenic Route?

Why is this Skywest crj from Chicago to Madison doing holds over northern Wisconsin? Just curious to any ideas. some sort of test flight or maintenance?

This is the flight in question: … /KORD/KMSN

Look a the first flight on 5 March. It has “diverted” in the duration column. It was scheduled to fly ORD to CWA. It looks like it was circling CWA but then diverted to MSN.

Maybe they’ll try to take it up to FL450.

[Capt]That’s FL 4-5-0, Yeah Dude, unbefuckinleivabe, dude. Oh sht, do you see my joint?

[FO]Yeah Dude, it’s next to your martini…mellow out dude.

Heavy fog here yesterday, if that means anything.
