More than a century ago, legendary explorer Ernest Shackleton sailed from England with the goal of becoming the first explorer to cross Antartica. He never reached it, however, as his ship became stuck in a massive block of ice, where it stayed for more than 2 months. Remarkably, Shackleton's entire crew survived. Leading his men with compassion and bravery, Shackleton and his crew escaped and were able to return to England. The ship however, stayed behind, hidden until recently.
