The sinking of SS Titanic, 14 April 1912. An artist’s impression of the ship going down. Operated by the White Star Line, on 14 April 1912 SS Titanic struck an iceberg in thick fog off Newfoundland. She was the largest and most luxurious ocean liner of her time, and thought to be unsinkable. In the collision five of her watertight compartments were compromised and she sank. Out of the 2228 people on board, only 705 survived. A major cause of the loss of life was the insufficient number of lifeboats she carried. (Photo by Ann Ronan Pictures/Print Collector/Getty Images)
