Inside the Milwaukee Airport is museum of the airport's history. As opposed to the hustle and bustle of O'Hare, Mitchell Airport is relaxed, and you can take the time to learn about the great General Billy Mitchell (of Mitchell Airport, Mitchell Park, Mitchell Blvd, etc. fame). He argued for American aviation supremacy before anyone else took him seriously. At least until he got court martialed. Oh, and you can see some of the remains of the greatest airline ever in American history.
