Breve história - o piloto da nave espacial precisa de segundo personalidade para voar navio
A citação de Ran al'Thor de Construindo Novos Mundos, 1946-1959: A Era de Carnell, Volume Um :
"Captain Bedlam" (69), reprinted from the December 1957 US Space Adventures, proposes that humans can't stand up to the stress of space flight, and the only way to get around the problem is to induce a second personality to pilot the spaceships. The main personality never sees space and experiences only periods of amnesia. But the protagonist gets into real trouble, and his main personality wakes up just long enough to see the stars, before the third personality is invoked to deal with the emergency at the cost of considerable injury.
