When a ship it sinks it leaves a path of debris (objects from within the ship or objects breaking off). Depending how deep the vessel sinks this debris can be scattered over a large distance. On a shorter descent, the debris falls more or less vertically. However, as the Titanic sank 21/2 miles a huge debris field was expected.
