Maybe not with the Titanic, that ship is too slow as it is.
I'll just make a "special" mission with Titanic pointed towards an object far away, so I can always start up at the same point and try to hit the object whenever I can
All just so I can get some good sinking pictures
But I do wonder if you can actually create holes in the Titanic from hitting something. I thought you couldn't do it with the Sherpa, but then I saw a screen shot and the thing was all bashed in at the front and side. But, that's because it was thrown into the air and fell back to earth
**oh, here's the link to the topic with that screen shot http://www.shipsim.com/ShipSimForum/index.php/topic,1192.0.html
