You know the old saying, "Build a better mouse trap and the world will beat a path to your door?"  Sunday morning on The World of Aviation, our guest did exactly that, but it wasn't a mouse trap, he saw a need for better hanger doors.  Michael Schweiss is a Minnesota kid who started Schweiss Doors, the most recognized brand name in hydraulic and bi-fold doors.  Mike is going to be inducted into the Minnesota Aviation Hall of Fame on April 20th.
