The rusted prow of the R.M.S. Titanic ocean liner sits in the dark waters of the North Atlantic ocean off the coast of New Foundland. While this is an iconic image of the sunken ship, the boiler of the Titanic plays a more important role in the ship's history. Until its discovery in 1985, the location of the Titanic was a mystery. Robert Ballard, co-discoverer of the ship, said that he and his team knew they had found Titanic when the team spotted its boiler on the ocean floor.
