A maritime expert tells the story of the sister ships using previously unseen pictures, passenger diaries, and deck plans, illustrating Olympic's successful career; the premature ends of her two unfortunate sisters; and the experiences of those onboard. Designed for passenger comfort, they were intended to provide luxurious surroundings and safe, reliable service rather than record-breaking speed. Ironically, fate decreed that only Olympic would ever complete a single commercial voyage and she went on to serve for a quarter of a century in peace and war. Titanic's name would become infamous after she sank on her maiden voyage. The third sister, Britannic, saw a brief and commendable career as a hospital ship during World War I, sinking in the Aegean Sea in 1916.
