The Impassable Sky

As every child knows, The Gunfighters was the last Doctor Who story to have individual episodes until The Five Doctors, A Fix With Sontarans, Doctor Who (also known as the TV movie) and then Rose onwards.

On that basis, my Companion Chronicles squeezed into gaps before The Gunfighters have all had individual episode titles, at least on the scripts. I got asked online what the titles were for my latest effort, The Cold Equations, and a clever chap called Chris of Fenric then went and made this, which I like.
