The Sahara is the largest hot desert on Earth. Its various landforms are almost exclusively formed by wind and include everything from salt flats through to stone plateaus. The sand sea (erg) only accounts for roughly 20% of its total area. The only possibility to see the vast extension of the desert and the various pattern of dunes is from the bird’s eye perspective.
