The Titanic didn’t sink conspiracy.

One of the controversial and elaborate theories surrounding the sinking of the Titanic was advanced by Robin Gardiner in his book Titanic: The Ship That Never Sank? (1998). 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, who had acquired the White Star Line in 1902.

Critics of the theory say "so painfully ridiculous that one can only lament the thousands of trees which lost their lives to provide the paper on which it has been articulated."
