The infamous ship Endurance, which sank in Antarctica in 1915, wasn't as well built for a polar voyage as previously thought — and its owner was likely aware of its shortcomings.
Explorer Ernest Shackleton sailed Endurance to Antarctica in 1914 as part of a failed British expedition to cross the continent on foot. The ship became trapped in the ice in the Weddell Sea, where it remained for 10 months before it sank, supposedly when its rudder was torn off by the ice. But there's more to the story, according to a new study.
