Anon's wouldn't think there may be something, apart from it not being the Titanic, on board that may be very important, would they? I for one am well satisfied with the video, no need to risk being turned into a softball when the sub implodes. That brings up another point, surly they have sonar on the mother ship so no implosion? Haven't heard. I'm really not buying it, especially since the US wont let other countries help!
