Elevations of the White Star Line triple-screw steamers built by Harland & Wolff in Belfast. The largest vessel in the world at the time and older sister of the Titanic, Olympic was launched on 20 October, 1910 until she was scrapped in 1935 after striking and sinking the famous Nantucket lightship off the eastern coast of the United States. Titanic struck an iceberg in fog south of Newfoundland en route from Southampton to New York on 14 April 1912. She had been believed by her designers to be unsinkable, but five of the vessel's watertight compartments ruptured, and over 1500 lives were lost. Illustration from 'The White Star triple-screw Atlantic liners 'Olympic' and 'Titanic', 45,000 tons : the largest steamships in the world', published in Newcastle-on-Tyne in 1911.
