Were you refering to the ca 1915 print, which shows the third funnel fallen across the boat deck?
That didnt happen but, as I said in a different thread yesterday, reliable witneses saw something fall from the ship, forward on the starboard side, during the final stages of the sinking. They described it as everything from a funnel, to deck gear, to a chunk of the side breaking off, so it is impossible to definitely say what it was. However, since the funnel debris seems to be evenly aligned on the bottom it is safe to say that it wasnt a funnel.
