Class III Bandragian freighter
From Tardis Wiki, the free Doctor Who reference
A Class III Bandragian freighter was a cargo-carrying spacecraft used by some Bandragians.
When Gein's Class III freighter crash landed into Earth's North Sea, sometime prior to the Second World War, Gein disguised himself as a human and hijaked a submarine, intending to recover his ship. When the Eleventh Doctor found out about this he offered Gein a lift home in his TARDIS.
So that the freighter wouldn't discovered by the Nazis, changing history, the Doctor altered the ship's biocomposition – making it an attractive, tasty and digestible food source for sea life, which quickly ate it. The ship decomposed before it was discovered. (COMIC: Sub-species)
