Sean D. Tucker donated his custom-built biplane, the Aviation Specialties Unlimited Challenger III, to the Museum for display in the future "Thomas W. Haas We All Fly" gallery, slated to open in 2022. Displaying the Challenger III in the gallery will showcase the technological achievements of the aircraft, including its eight ailerons that enhanced maneuverability and the engine’s cold-air induction system and state-of-the art fuel injection.
