The BBC archives erase dozens more episodes of Doctor Who due to an ongoing space crunch and an impending change of video standard from 405-line PAL to 625-line PAL. Whereas the first round of tape-wiping in 1967 was targeted at episodes involving the first Doctor, this round marks episodes featuring the current Doctor, Patrick Troughton, for deletion. The fourth episode of The Tenth Planet – Hartnell’s swan song in the role of the Doctor – is erased at this time, as well as a curious scattershot selection of Troughton episodes.
Part one of the classic 
The BBC announces that a private collector has returned part two of the mostly-missing twelve-part Doctor Who story, The Daleks’ Master Plan, to its archives. Last seen in late 1965, the episode has been in the possession of the former chief engineer of the competing Yorkshire Television network ever since the early ’70s – when he snatched it from the BBC archives (where he was a trainee at the time) rather than destroying it as ordered. The 25-minute episode, subtitled Day Of Armageddon, is handed over to the Doctor Who Restoration Team, which oversees the preservation and restoration of past episodes for DVD release.
The BBC announces that broadcast archive company TIEA has recovered nine missing episodes of Doctor Who, all from the Patrick Troughton era, completing one story of which only one episode was previous held in the BBC archives (The Enemy Of The World) and almost completing another story (The Web Of Fear), which is now missing only the third of its six episodes. All nine episodes have been found in surprisingly good condition in at a regional broadcaster in Nigeria, which had received the episodes from a Hong Kong broadcaster in the early 1970s. All nine episodes are made available for digital download, with remastered DVD releases due in time for the 50th anniversary of Doctor Who in November 2013. The find had been the subject of wild speculation on the internet for months.
