Two lost episodes of Doctor Who were found in a TV engineer's private collection. The episodes feature the first two Doctors, William Hartnell and Patrick Troughton. One episode, Airlock, was part of a four-parter titled Galaxy Four. The other is The Underwater Menace, about the rebirth of Atlantis. From BBC News:
The announcement was made on Sunday at Missing Believed Wiped, an event held at the British Film Institute (BFI)…
Former TV engineer, Terry Burnett… bought them at a school fete in Hampshire in the 1980s.
Mr Burnett had no idea the BBC did not have the recordings – it was only when he mentioned them casually in conversation to Ralph Montagu, head of heritage at Radio Times, that their significance was recognized…
The find makes only a modest dent in the number of missing episodes, with 106 installments broadcast between 1964 and 1969 still being sought.
