I still believe the theory : that the Titanic sailed until 1935.
The Titanic developed several engine problems and the owners did not want to delay the maiden voyage. They docked in Ireland and out-fitted the identical ship Olympic and re-named it the Titanic and visa versa.
But the Olympic had a deep seated slow burning fire in it's coal reserves that the owners thought could be overcome on the maiden voyage but it weakened the structure and thus when the iceberg struck it had no hope.
So the Olympic sank and the Titanic stayed in service until 1935.
