Like everything else, from all over the place. There's "Titanic - The Ship That Never Sank", by Robin Gardner. There's The Creature from Jekyll Island: A Second Look at the Federal Reserve" by G. Edward Griffin. There's all sorts of things about Morgan (read how the sadistic bastard treated Tesla).
And the Web, of course. In fact, searching the above books as they are referenced in web articles is a good start.
As astounding as the Olympic-Titanic name swap appears (just think of the audacity), it does bear up under scrutiny. Subtle things like the numbers of portholes, the extend of external promenade coverings, and the placement of external shear lines are clearly evident in comparison photos. And I read that now they've found eveidence of different letters etched in the steel of the submerged "Titanic" where the name letters have dropped off.
The important thing to remember, I think, is that the people who did this are the same people who created entire wars for profit and social control. Whacking a ship in order to murder renegades within their ranks in order to gain control over America's financial system was probably so trivial to them, that they had assistants handle it.
What's chilling is that the same mindset still controls the same "elites" today.
Thanks, I never read that book but I do know what you are saying about the “Elites”.
