I thought this one was rather weak as well, and unconvincing (I’m working backwards in these comments from Kerblam!). I can’t comment upon how likely they would be zapped from one world to an unmanned spaceship that had no “easy” manual over-ride (God help us, if that’s what we have in store for us with cars!) but why, oh why did we have to have a man giving birth to a boy-creature. Surely there was another medical emergency that could have been featured?
