"Richard Hammond's Engineering Connections" finds the "Top Gear" presenter investigating how major feats of engineering were achieved through technological innovation. In the opening episode, he reveals how a 19th-century rocket, a bicycle pump and an ancient Mongol bow helped in the design of the double-decker Airbus A380, the world's largest passenger airliner. The first of four episodes premiered on National Geographic in 2008 and then on BBC Two in 2009.
