Expedition Africa on HISTORY episode June 28th (promo)Airs Sunday June 28th at 10/9c on HISTORY. DANGER IN THE DESERT - The explorers arrive at the Bahi Swamp--despite its name, a harsh desert landscape. While there, they arrange to hire donkeys to help carry supplies for the next stage of the trip. The plan is to beat the heat by setting out at 4am, but things don't work out as planned. As the sun is hitting its peak, the explorers see the massive stretch of desert awaiting them: HOT--no shade, no protection and a long way to go. The philosophical divisions between some of the group manifest themselves in physical separations. Join other fans on Facebook: http://www.facebook.com/History .
