A group of dedicated Doctor Who fans tracked down at least 100 long-lost episodes of the show gathering dust more than 3,000 miles away in Ethiopia.
The recovered episodes from the 60s include much-loved scenes from The Crusade, The Enemy of the World and The Ice Warriors series.
In the four-part Crusade story [the First Doctor, played by William] Hartnell, and his assistant Vicki, played by Maureen O’Brien, arrive in the TARDIS in Palestine in the 12th century just as King Richard the Lionheart is doing battle with the Saracen ruler Saladin.
After each airing only once between 1964 and 1969, copies were sold to the Ethiopian Agency and the BBC then lost or wiped the originals.
The BBC hopes to announce this discovery next month on the 50th Anniversary Special.
