Top Gear Africa Special Part 1
In the first of a two-part special, Jeremy Clarkson, Richard Hammond and James May are in Africa with a simple mission - to find the definitive source of the Nile. Over the years many explorers claim to have already done just that, but the `Top Gear' trio believe that they can do better by travelling further and faster than any exploration team in history using only grit, ingenuity and three ageing estate cars.
