After the World Trade Centre was destroyed by terrorists (I don't believe that 'inside job' conspiracy), a ship was made out of the steel that was recovered. The USS New York is a battleship, which seems appropriate.
What is really spooky about this is that while the excavations are underway for new building at the site of the World Trade Centre, they uncovered the remains of... a ship. Part of a ship, anyway, from the 1700's and most probably used as landfill to extend Manhattan's land area.
So the building that became a ship was always standing on top of a ship. Funny how things tend to go in circles, isn't it?
The one worry in all this is that if they are digging foundations in a place where a very tall building stood and they've found something they haven't seen before... were the previous foundations really deep enough?
