Slipback (audio story)

Slipback by Eric Saward was the first original Doctor Who serial to be produced for radio. It was first broadcast by BBC Radio during the summer of 1985, during a period when the televised series was on hiatus for a year. Colin Baker and Nicola Bryant reprised their TV roles for the production, with also included a number of other cast members. It, along with the earlier Doctor Who and the Pescatons, is considered a forerunner of the later Big Finish Productions audio dramas. It followed nearly a decade later by two more radio dramas starring Jon Pertwee and in 2007 by a new made-for-radio series for BBC7 (produced by Big Finish) starring Paul McGann.

Slipback was released to cassette tape by BBC Audio, and later to CD by Silva Screen Records.

 * According to this story, the Vipod Mor is responsible for the Big Bang, yet a previous televised serial, Terminus, established that another vessel was responsible for triggering the explosion. The Big Bang was such a monumental event, it's possible it needed more than one catalyst. The fact the Doctor states he needs to read up on his history could also reflect the fact that he appears to have forgotten the Terminus vessel himself.

Novelisation
Novelised as Slipback by Eric Saward in 1986. It was the first Target Books novelisation not based upon a televised story. The book is notable for not featuring the Doctor or Peri for its first half, as Saward expands the radio story to include background on the various characters.
