The Titanic is one of the most famous maritime disasters of all time, but did the Titanic really sink on the morning of 15 April 1912? Titanic's older sister, the nearly identical Olympic, was involved in a serious accident in September 1911 – an accident that may have made her a liability to her owners the White Star Line. Since 1912 rumours of a conspiracy to switch the two sisters in an elaborate insurance scam has always loomed behind the tragic story of the Titanic. Could the White Star Line have really switched the Olympic with her near identical sister in a ruse to intentionally sink their mortally damaged flagship in April 1912, in order to cash in on the insurance policy? Laying bare the famous conspiracy theory, world-respected Titanic researchers investigate claims that the sister ships were switched in an insurance scam and provide definitive proof for whether it could - or could not - have happened.

Did the Titanic really sink? Or was it sister ship Olympic? Was it a massive cover-up or an insurance scam? These and many other questions are raised in Robin Gardiner's brilliantly entertaining read which reveals a fascinating version of what really happened on that terrible night in April 1912.

Sitting around a dining-room table in 1907, the owners of the White Star Line discussed their competition to the newly-built Cunard liners, Lusitania and Mauretania. From that smoke-filled room came the first designs of three White Star superliners. Olympic and Titanic were to be built at Harland & Wolff's yard in Belfast, while the third ship was to follow after construction had been completed on the first pair of sisters. The only ship to make a return passenger voyage was Olympic and she was always overshadowed by her younger sisters. This is the definitive story of Titanic's sister RMS Olympic. First published in 2004 to critical acclaim, this new edition presents a revised expanded work from one the most successful maritime authors at work in Britain today.

A pictorial celebration of the world-famous sister ships: the Olympic-class liners 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 transport 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.

The wireless crackled, an SOS was broadcast. Olympic, Titanic's older sister ship was a mere 350 miles away from the sinking liner. Would Olympic reach her in time -
