The Africa Special is a Top Gear special in which Jeremy Clarkson, Richard Hammond and James May attempt to find the true source of the River Nile in secondhand estate cars on a budget. It was the first special in Top Gear history to be split into two parts and air across two episodes, airing as the sixth and seventh episodes in the nineteenth series. The team traveled through Central Africa to achieve this goal, starting in Uganda and traveling through Rwanda to reach their final destination in Tanzania. The special was originally slated as a Christmas Special for 2012 and was filmed in the same year, however it was pushed back and aired in 2013 instead. (thetvdb.com)
