Other mistake: Several shots are repeated during the implosion of the priory.
Continuity mistake: The TARDIS is missing its light the first time it's seen.
Continuity mistake: In the opening TARDIS scene, after the TARDIS lurches from the time scanner, the Doctor's hat rack can be seen standing upright. Then Leela picks it up in the next scene.
Continuity mistake: After shooting the two guards near the beginning of episode three, K-9's nose blaster retracts twice - one in close-up, once in medium shot.
Continuity mistake: The Gatherer gleefully states that being on the roof is a fine of 500 talmars. Later, Cordo says it is 5 talmars.
Revealing mistake: In episode two, when Leela and Mandrell are arguing about raiding the Correction Center, the camera bumps against something.
Underworld - S15-E5
Revealing mistake: The CSO caves are awful throughout, but one of the worst incidents is in episode three when Leela talks to Idas about a revolution and they both run right through a rock.
Underworld - S15-E5
Continuity mistake: When the Doctor races out of the R1C with the fission bombs in episode four, Leela follows, carrying a shield gun. She steps into the cave and is only holding her knife. Later, she has her shield gun back.
Underworld - S15-E5
Factual error: While it's true the centre of a planet would have no net gravity, the weightless condition would be everywhere, not concentrated in a convenient shaft.
Underworld - S15-E5
Revealing mistake: The pacifier devise is obviously a stage lamp.
Plot hole: In the middle of chasing the Doctor, Stor abandons the idea of controlling Gallifrey in favour of destroying it for no readily apparent reason.
Continuity mistake: When the Doctor shoots Stor with the De-Mat Gun, the flash starts on Stor's left-hand side, engulfs him, then jumps substantially to the right before whiting out the frame.
Plot hole: Leela's decision to stay with Andred is very sudden. They barely speak during the serial.
Continuity mistake: The Doctor has his scarf when he first meets with the Vardans. When he returns to the TARDIS, it is on the coat rack.
Answer: TARDISes are generally available for properly authorised use on Gallifrey; they're not usually assigned to a particular Timelord on a long-term basis. The Doctor stole his when he left his homeworld.
