Very soon, nature’s own censor – clouds – turned the view pure white. There are two major sorts of clouds as seen from a plane. One is thin, white smoke and resembles some sorts of semi-thick pudding. The other is a sort of living clay that lies somewhere between a mash-potato mountain range and holographic snow. Sometimes clouds look like a choppy sea, sometimes Alaska, sometimes a masonry explosion, sometimes giant frogs licking ice creams.
