Endurance: Expedition sets out to find Shackleton's lost ship

An expedition will set off from Cape Town this weekend to try to find the lost ship of Antarctic explorer Ernest Shackleton. His Endurance vessel sank in the Weddell Sea in 1915, crushed by ice. It's regarded as one of the most iconic wrecks in maritime history, but also one of the hardest to locate.
