Starship UK
Starship UK was a huge ship built to house the population of the United Kingdom (excluding Scotland, who used their own ship) during their journey to find another planet to live on, after the Earth (and all life on it) was threatened by Solar Flares.It was built around an organic Space Whale that was the last of its kind. The Eleventh Doctor and Amy Pond went there and found that it was run by the Smilers and the Governemt instead of its rightful queen who was Elizabeth the Tenth. They also found out that Elizabeth kept getting her memories whiped due to her orders and her feeling guilty about it because of the ethics in which where used to created it. In the end Doctor's companion Amy Pond resolved everything by setting the ship to self destruct. It did not becuase there where children on board and the Space Whale would not eat the children.
