Something very important about this episode, the Doctor is able to fly the TARDIS to the exact point in time and space he wanted. A sign for sure that he has gained greater control over the TARDIS as the years have gone by.
The Doctor has always had the ability to do so.
Any time he's been unable, whether stated on screen or not, it' because he's been working an angle.
He's been able to pilot the TARDIS with pinpoint accuracy far too many times for there to be any other explanation.
