A documentary on how Cornwall became a hub for the world's communications, from the first transatlantic radio signal to modern undersea fibre cables. It describes how cable landing stations and the systems are put together.
HN 推荐的原因： Recommended as a rare look at the unmarked buildings and infrastructure where undersea cables come ashore.
