The Swedish warship restored after 300 years

In 1628, at the height of Sweden’s military expansion, the Swedish navy built a new flagship, the Vasa. At the time it was the most heavily armed ship in the world. But two hours into its maiden voyage, it sank in Stockholm's harbour. It remained there for more than three hundred years, until its discovery in 1961. Tim Mansel hears from the former Swedish naval officer, Bertil Daggfeldt, about the day that the warship was recovered in near-perfect condition.
