The cup is miles up, and you have a limited view out of it. Would need to get to the edge and look down to see the ground, at which points... oops!Yeah, the radio series stretched the whole Shoe Event Horizon bit (which took a paragraph in the origiinal book) to like an episode and a half. IIRC, the scene with Arthur's statue was part of that.
That bit actually confused me, to be honest. Zaphod and the others are in one of the statue's ears and he says he can't see the ground. How the hell?No matter how high up they were, they should be able to see it.
Oh well, maybe there was fog or something...
