Who Sunk The Titanic? yes, Who, not What...

I don't buy it..

As already stated it would have been much easier to just hire people to kill them, and yes, back in that time frame, it wouldn't have been much of a problem to get away with it. We're not talking CSI style DNA testing.

The Titanic hit an iceberg, it was tragic, that's all there was to it. At this point in time we have been to the bottom of the ocean and seen it, there's not much to dispute.

Plus, there ARE differences between the Olympic and the Titanic that would have been noticeable and would have been noticed, if not by the survivors, then by the return to the titanic.
