When the Titanic struck an iceberg in the North Atlantic on April 14, 1912, it took the ship 2 hours and 40 minutes to sink. I don't necessarily know why you would want to, but now you can watch a highly detailed animation of the ship sinking in realtime, all 2h 40m. I can't quite figure out if this is appropriate or not, although when I think about the inevitable realtime 9/11 version, perhaps it isn't.
