An unnamed Kenya CAA official has been reported as stating "the plane has crashed" ..

SA news sources have stated that witnesses near Lolodorf have reported hearing "a loud explosion" ..
The scenario doesn't look good .. heavily timbered country is reported where the plane is reputed to have gone down .. thus making it harder to find wreckage, and more difficult for possible survivors. God speed the searchers.
I can't imagine that any top-class rescue teams are ready to roll .. or that quality treatment facilities are nearby, either ..
