evidence: Olympic exchange hypothesis [edit]One of the controversial[5][6] and elaborate theories surrounding the sinking of the Titanic was advanced by Robin Gardiner in his book Titanic: The Ship That Never Sank? (1998).[7] Gardiner draws on several events and coincidences that occurred in the months, days, and hours leading up to the sinking of the Titanic, and concludes that the ship that sank was in fact Titanic's sister ship Olympic, disguised as Titanic, as an insurance scam by its owners, the International Mercantile Marine Group, controlled by American financier J.P. Morgan that had acquired the White Star Line in 1902.
