Cool news for the serious Who fans (me included). The BBC today revealed that an episode of the 1965 First Doctor story, Galaxy 4, has been recovered along with an episode of the 1967 Second Doctor story, The Underwater Menace. Neither of these stories exist in their entirety in the BBC archives. Each find is significant: this is now the only episode of Galaxy 4 in existence, and while a different episode of The Underwater Menace was discovered some years ago, the “new” one is an earlier episode, and is now the earliest Second Doctor episode in the archives.
If you want to read the whole story, including a brief explanation of why there are missing episodes in the Doctor Who archive at the BBC, here’s the article on the Radio Times website.
