The Edge of Destruction (TV story)

Summary
A mysterious blast renders the TARDIS crew unconscious. They awake disorientated and soon find that the TARDIS is strangely malfunctioning. As all of the systems breakdown, the behaviour of the crew becomes more erratic. Soon the Doctor comes to believe that the school teachers are behind the malfunctions in an attempt to blackmail him into taking them home.

Gradually it becomes clear that the problems are a warning from the TARDIS. It seems that a spring has broken on the fast return switch causing the TARDIS to travel back through time towards the creation of the Milky Way Galaxy. The Doctor corrects the problem and the travellers are able to escape.

Continuity

 * The fast return switch is again used in The Witch Hunters, Seasons of Fear and Neverland.
 * The TARDIS power source is beneath the central console.
 * The TARDIS has an inbuilt memory of all the locations it has previously visited.
 * Despite the size of the TARDIS Susan and Barbara share a sleeping area.
 * Susan and the Doctor share a telepathic link with each other and the TARDIS
 * The only other episodes to feaure only the Doctor and his companion(s) is the 2005 Children In Need Special.
 * The Doctor and Susan have visited the planet Quinnis in the fourth universe four of five journeys ago.

Discontinuity

 * In episode 1 the studio floor is visible in the "white void" outside the TARDIS
 * Fast Return Switch is written in felt tip pen on the console
 * There are a couple of serious dialogue problems with William Hartnell. At one point he repeats the same line twice causing problems for the other actors.
 * William Hartnell completely omits the scripted explanation for the melted clock faces
 * While being central to the plot the idea that a device such as the TARDIS would use a spring seems a little strange
