imo the Titanic was really the Olympic which was previously damaged by crashing into another ship, they swapped them and were planning to sink it for the insurance money, JP Morgan also had another ship waiting near by where they planned to sink the "titanic" but they forgot the navigation charts so ended up too far away, i think the idea was to save most of them probably not the ones who opposed the federal reserve act as it was said they were already dead before it sank.

Here is some pics of the two ships and the port holes that shows that it was the Olympic that sank Port holes Comparison

Article Explaining it all

I am guessing that after this mishap they are going to prevent anyone else to go down there and take a look as its possible to see that its the Olympic due to things like the window placements etc.
