This is a really strong conclusion to the Hypothetical Gentleman story that started in...well, 'The Hypothetical Gentlemen'. It's quite odd for a 'finale' in that it doesn't feature the same companions as in that story - The Hypothetical Gentlemen is an Amy and Rory story, but this one is a Clara Oswald adventure. Likely because when the comic was published Amy and Rory had left on TV and Clara was the new companion.

It's an amazing story concerning these various aircrafts and spacecrafts that have fallen through this white hole - among them some World War II pilots with an atomic bomb to be dropped over Japan. This story features an unusual - but awesome - take on the Matrix, and a totally badass Clara Oswald moment.
