Doctor Who: 10 Secrets Of The TARDIS You Need To Know

10. It Has Been Faulty Since The Series Began

Most of you know by now that The Doctor has been zipping through space and time without a care for the where or why since he first stowed away from his home planet of Gallifrey, 'borrowing' the TARDIS from a repair shop with only his granddaughter for company, and a dream of a responsibility-free life of adventure (if only, Doc... if only). However, the TARDIS was not always the instantly recognisable pillar of pop-culture that it is today.

To help him blend in with the natural surroundings of 1960's England on what was supposedly his first real outing in the vessel, the TARDIS did a quick scan of the area and determined the box to be the most perfectly innocuous shape to have suddenly appeared on the street corner. What The Doctor didn't realise was that this "chameleon circuit" had actually developed a fault - hence the repair shop. All it took was that single journey and the circuit was jammed for good, giving us that look we know and love.

To top it off, the navigation system is also completely unusable, a fact that was compounded by 2013's The Name of The Doctor in which a Gallifreyan with an uncanny resemblance to future companion Clara Oswald remarks to The Doctor that a time machine with a broken navigation would be "much more fun". Each to their own!
