An important revision of the traditional image of the spaceship was made in Anne McCaffrey's Helva stories, beginning in 1961 with The Ship Who Sang. This series is set in a future when severely disabled children are given the chance to become starships by becoming enclosed in a metal shell connected directly to their brain. This is an enabling procedure involving 'schooling' (not programming) and complex neural and sensory connections being constructed through the titanium shell. In this respect, the 'shell-people' represent an early form of cyborg, and McCaffrey's narrative replaces central technological control with the individual investigations and self-modifications by Helva herself in devising a means of singing.
