Try this link for an idea of DRC helicopter operations.
This video might show you what the area is like and a bit of what the work is like, but it is more about show boating and flying irresponsibly. The rest of us don't fly like that in the DRC... it's just too risky - especially as there is no help when your finger comes out your ass...!!!
Sure the SA CAA would love a copy of that for their next inspection on BAC operations...
