I heard something about this as well, except I read that the Titanic was actually hit by a 688 boat, which launched a Tomahawk from 450 miles out. I believe it was the USS Dallas that lauched the missile. The Dallas at the time was chasing a new type Russian sub. The light the captian of the Californian saw was a Coast Guard HH-60 dropping of rescue swimmers to help the survivors.
The Trilateral Commission and the Illuminati made sure the survivors never told the real story.
It must be true, because Michael Rivero says it is! It's all a U.S. Navy coverup, I tell you! The evidence went down with the Kursk after a Navy submarine rammed it!
