So after 5 seasons Jon Pertwee bowed out as the Doctor. His suave more action orientated take on the time lord oversaw a very popular era with consistently high ratings with some notable highs. Having been "killed off" the Daleks returned after 5 years in the super Day of the Daleks. For the 10th anniversary he teamed up with the previous Doctors to save the Time Lords in The Three Doctors and of course he did battle with the Master on many occasion. Some of other noticeable stories include- anything from his first season. The Sea Devils, Carnival of Monsters, Frontier In Space, Invasion of the Dinosaurs and his exit in Planet of the Spiders.....
The 3rd Doctor would go out bravely, facing his fears and making 10 look like a whiny little pussy. Planet of the Spiders tied together a number of minor threads from Pertwee's run as the Doctor. It also was the first story to feature the term "regeneration" as an explanation for the Doctors ability to metamorphosize into a new man.
A NEW FACE"There's no point being grown-up if you can't be childish sometimes."
Tom Baker had been chosen to play the new Doctor. It would be one of the final acts of the outgoing Barry Letts and one that would take the show on to new heights. The 4th Doctor began life at UNIT HQ, in the story "Robot", and quickly had them bewildered. He wasn't the only new face. Harry Sullivan was a royal marine surgeon who had joined UNIT. He had been previously named in Planet of the Spiders before appearing in Robot, the opener to season 12.
Harry would join Sarah and the new Doctor for the adventures to come......
Story 13-
The Ark in SpaceIn the far future the TARDIS, containing the freshly regenerated Doctor alongside Sarah and Harry, lands on a seemingly deserted space station orbiting Earth.

. I am keen to check out the Tom Baker era, though, and so perhaps this could be a great time to jump back on board.
