"The hell kind of question is that?" Handy asked. "Nothing goes up and doesn't come down." Which he knew wasn't true. Fundamentally, if you broke orbit and spiralled off into space, 'technically' you'd never come down. But then you'd never go up either since direction is near meaningless in space. Still, he got the distinct impression that whatever it was going to accept as an answer wasn't going to be something beyond the planet. It was taller than trees too, but why would that be relevant if it always went up yet never came down?
