This unique book explores, with many comparison photographs and text, the theory promoted by some that Olympic was switched in place of Titanic. The basis was that on September 20, 1911, Olympic sailed from Southampton and collided with HMS Hawke. Did Olympic suffer from such damage that her structural integrity was compromised––wounds that were so severe that she was not worth repairing? Was she switched with her near identical sister Titanic in a ruse to intentionally sink their mortally damaged flagship on April 15, 1912. Incredibly off the wall as this plot seems, books have been written on this subject convincing many to believe. The authors are two young men who have spent many years specializing, researching and amassing a photographic collection of both ships. This book addresses all the questions with a wealth of evidence and provides the final answer to which wreck actually lies on the bottom of the North Atlantic.
