Alaska (spaceship)

The Alaska was a spaceship which crashed on the Dalek Asylum, and launched several escape pods to the surface. There were at least two survivors: One of the crew members was Harvey, who died soon after on the frigid surface and was reanimated by the nanocloud field, becoming a Dalek puppet along with the other crew members who died on impact. The other was Oswin Oswald, who instead used a ladder to descend below the surface of the planet, but was captured and fully converted into a Dalek. However, she managed to retain her human consciousness within a delusion of life (believing she had set up camp in the cockpit of a crashed spaceship), and it was this humanity that caused her to hack the Daleks' databanks in the real world, deleting all Dalek memory of the Doctor.
