tells the story of how deep-sea mapping company Magellan created “the most precise model of the Titanic ever created: a full-scale, 1:1 digital twin, accurate down to the rivet,” according to a statement from National Geographic, published Tuesday.

When Titanic set sail on April 10, 1912, she was the largest passenger ship in service and considered unsinkable. Just four days later, Titanic’s maiden voyage became an international tragedy when she struck an iceberg in the North Atlantic at 11:40 p.m. April 14. She sank in less than three hours. The ship did not have enough lifeboats for the approximately 2,220 people on board. More than 1,500 people died in the accident, and Titanic became the most famous shipwreck in history. There were just over 700 survivors. (CNN)
