The Caves of Androzani - S21-E6
Trivia: On the DVD commentary, Peter Davison remarks that when Christopher Gable whacked him across the face with the back of his hand, it actually hurt quite a bit, even though they'd discussed it beforehand. Davison believes that Gable couldn't see him properly with his mask on, although a more likely explanation is that Gable got too carried away.
Trivia: During production of this story, Peter Davison (The Doctor) and Janet Fielding (Tegan) announced their departures from the series. Producer John Nathan-Turner had offered Davison a fourth season in his role, but he feared being typecast if he stayed beyond three years on the programme.

Trivia: Peter Davison named this as his favourite serial from his three years on the show. He enjoyed the script and working with the director, Graeme Harper, praising Harper's direction for bringing more pace and energy to the programme, as well as a more cinematic style, which was lacking in his earlier stories. Davison has said that if he had been given more scripts like The Caves of Androzani, he would have considered staying on for a fourth season.






Answer: It was never destroyed on-screen; it was intact at the end of the TV movie, and destroyed by the start of the 2005 series. It was destroyed in the novel "The Ancestor Cell," but in a completely different manner to what happened in the series.
