Alaska (spaceship)

Alaska was a spaceship, which crashed on the Dalek Asylum launching 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 surface and was reanimated by the nanogenes field becoming half-Dalek along with the other crew members who died on impact. Oswin Oswald instead used a ladder to descend below the surface of the planet but was captured and fully converted into a Dalek, she however managed to retain her human conciousness within a delusion of life in a crashed space ship cockpit and hack the Daleks systems in the real world deleting all Dalek memory of The Doctor.
