Soar through the high points of American aviation: from the Wright brothers and their competitors to the military pilots who first circumnavigated the globe, from the initial space rocket to the moon walk, from the earliest manmade satellite to today’s spy drones. The book also describes what inventions—such as rocket propulsion, the wind tunnel, and the silicon chip—helped move flight upward and beyond. Profusely illustrated with objects from the Smithsonian’s collection, Milestones of Flight provides an inspiring look at America’s contributions to aviation.
