RMS Titanic

The Titanic was an early earth luxury liner known famously for its collision with an iceberg.

Doctors involvement with the Titanic

 * The doctor (in his 9th incarnation) got several people to decide not to board the liner, intern saving their lives.
 * He also went on the ship, surviving by clinging on to the Iceberg.
 * the doctor (#10), just after fixing the TARDIS, is shoked when the Titanic rams into it, some how being able to break through. (DW:Voyage of the Damned)
 * the Doctor (#7) traveled on the ship in The Left-Handed Hummingbird by Kate Orman.
