Full Circle - S18-E3
Corrected entry: Romana gives the TARDIS's weight as five million kilograms in the planet's gravity. This is totally inconsistent with the TARDIS's weight in the rest of the series - for instance, in the third Doctor's time, a few soldiers were enough to lift it. And it can't be because of the planet having high gravity, as the Doctor and Romana would have been killed and K-9 crushed whenever they went outside the TARDIS.
Corrected entry: Peter Davison's hair is blonde, however when he has just regenerated from Tom Baker, it is dark black.
Correction: And what does this reveal, exactly? His body's just been effectively torn apart and reconstituted and it's established that the regeneration energies remain in the body for several hours after the event. Hardly unreasonable, given that he doesn't establish anything even close to equilibrium for some considerable time after the event, that, when we see him post-regeneration, his hair colour, which, by the way, is hardly dark black, more a light brown, might not quite have settled down yet.
Corrected entry: Much is made of the fact that Tigella revolves anti-clockwise, as though that was unusual. Eight of the nine planets that orbit our Sun revolve anti-clockwise. The one exception is Venus, and it revolves so slowly clockwise (a mere 4mph) that it is barely rotating at all.
Correction: Romana is talking nonsense to the Gaztaks to buy time to escape.
Corrected entry: In episode 4, when the Doctor ages and de-ages, isn't it strange that his hair also ages and de-ages accordingly, but his clothes do not?
Correction: Clothes dont age.
Correction: There is no mistake. The outside has always weighed less than the inside, just like the outside is always smaller than the inside. Its outside weight is dependent on its chameleon camouflage, but in this episode they're talking about the interior weight. There have been episodes where people were unable to pull it if the chains were on inside, and in the episode Castrovalva, the weight of the TARDIS is much greater than 5 million kg. If that immense weight was always the case, it would crash through the floor of many locations where it materialised.

Referring to the new series, in the Twelfth Doctor episode "Flatline", the Doctor outright says that if he landed the TARDIS on Earth at its full weight it would crack the planet's crust.
