The BBC revealed today that two complete episodes of Doctor Who have been returned to the BBC Archives.
Firstly, the complete third episode of the William Hartnell story Galaxy 4, Air Lock has been recovered - prior to this only a short segment from the first episode remained in the archive with no telesnaps taken to show how the third episode and its characters would have looked.
Secondly, the complete second episode of Patrick Troughton's third story The Underwater Menace has also been recovered - making this the earliest complete episode for the Second Doctor to now exist in the Archives (alongside the existing episode three).
Both episodes were found via former TVS engineer Terry Burnett, who bought them at a school fête in Marchwood, Southampton back in the 1980s!
