Initial reports -- which obviously could change later -- indicated the plane did not descend or ascend, did not turn. It just disappeared. It was there, and then it wasn't. The plane's normal flight path, flown about four times a week, according to The Independent in Great Britain, would be along the Ouagadougou-Algiers air route, which would take it through Mali air space. Mali is mostly al-Qaeda controlled, but that control is concentrated in the north. The plane would have been flying into Mali at its southern boundary. Ouagadougou, Burkina Faso's national capitol, is about 120 south of the Mali border.
