Summary: Finally the TARDIS is being flown the way it should be.
There’s a knack to flying the TARDIS, and the Doctor is an old hand at it; he’s been doing it for hundreds of years, after all. Yes, it involves a lot of mad running around the central console, pushing this button, pulling that lever, pumping, cranking, twisting dials, but after so long it’s second nature; he barely even notices the effort he has to expend any more.
There’s no denying this is so much easier though, standing back and simply instructing the others on what to do. TARDISes are designed to be operated by six people, not one single pilot.
