On 19 July 1843 the SS Great Britain, Brunel's famous iron ship, was launched at Bristol by Prince Albert. Exactly 127 years later, the world's first propeller-driven Atlantic liner is due to return to her birthplace at the Jeffries dock in Bristol after the world's longest salvage operation. Magnus Magnusson introduces the first live broadcast from this historic ship, together with film, specially shot by Chronicle, of her dramatic rescue and her last 7,000-mile voyage from a lonely cove in the Falkland Islands.
