Titanic: The Mission - Season 1 Episode 2 The Anchor

The team casts the ship's 16-ton anchor, which in 1911 was the largest the world had seen, at the last steelworks in Britain in Sheffield. They then explore the West Midlands town of Netherton, where the original was made, before re-creating the publicity shot that celebrated its leaving the factory. The engineers also look at the coal industry that provided the energy necessary to build and power the Titanic.
