They eject us from planes when disaster strikes. They gently guide us to Earth from thousands of feet in the air. They transport us with amazing speed and remarkable safety. And they keep us alive in the most extreme environments humans have ever explored. This series tells the stories behind the machines and devices that help us survive in the skies--space suits, parachutes, ejection seats, and jet engines--and how they evolved from humble beginnings to incredible instruments that have changed the world and lifted us to new heights.
