Other mistake: The Brigadier says UNIT HQ is 'a Top Secret establishment'. It is, in fact, so secret that it has a large sign outside informing the world not only of its function, but also the name of the commanding officer.

Question: If the Doctor gets a TARDIS, does that mean other Timelords get a TARDIS as well?
