This story is one of Doctor Who's darkest yet, with the Doctor torn between saving the Bowie Base One crew from the Flood virus and leaving them to their fate. It's a harrowing tale by Phil Ford and Russell T Davies, as the Time Lord's later decision to rewrite a fixed point in time by rescuing the doomed astronauts results in Adelaide Brooke opting to take her own life.
