The idea of flying over the Sahara did appeal at first, but for much of it there was almost nothing to see – as one would expect, I suppose. Nothingness – at least, when seen from 35,000 feet – got boring rather quickly. However, flying over this huge expanse of water among the dunes did wake up the photographers amongst us for a while. Look closely enough at this shot and you can also get a sense of the curvature of the Earth: the horizon has a definite bend to it.
