The 47th episode of Doctor Who airs on the BBC. This is part two of the story now collectively known as The Dalek Invasion Of Earth, although the title of this individual episode makes it easily confused with the first season serial of the same (collective) name.
This timeline entry leads to an entry covering this entire Doctor Who serial; there are plans to write new episodic entries in the future. You can support this effort!
