        Higher and Faster

        Explore the social and economic factors as well as the engineering innovations that have driven—and continue to drive—both higher and faster commercial flight, in this interactive produced by WGBH and The Documentary Group. The first part of the interactive focuses on high-altitude flight. Using diagrams, infographics, and still images, it describes the benefits of flying higher with respect to safety, comfort, and fuel efficiency. It also explains the technological breakthroughs, namely in cabin pressurization and jet propulsion, that have enabled higher flight. The second part focuses on faster flight and, in particular, the challenges in aerodynamics, propulsion, and materials that manufacturers face as they seek to deliver new generations of high-speed passenger airplanes capable of supersonic (and even hypersonic!) flight. This resource is part of the Aerospace Engineering collection.
