Kelch Aviation Museum preserves the Golden Age of Aviation at Brodhead Airport in southern Wisconsin, telling how interwar record-breakers, barnstormers, airmail pilots and home-built aircraft helped turn flight into an industry. The nonprofit collection includes 19 vintage aircraft, original aircraft engines, aviation books and research archives, photographs, models, automobiles and hands-on exhibits that connect the machines with the people who built and flew them. Education, preservation and family programming are central to the visitor experience, with occasional aircraft activity and events tied to the living airport. Public access, guided-tour arrangements and accessibility support follow current operator guidance; confirm before travel. Visitor address: N2463 Airport Road, Brodhead, Wisconsin 53520, United States.
