Having flown across Namibia myself just recently, I was warned several times of the sensitivity of low flying in areas that are not formally marked as Park or Prohibited, and were operators made agreements with land owners and/or the government about conduct, something that is as far as I am aware of not published for "outsiders".
Examples are even found north of Wolvedans, and of course around the Rhino's in Damara. Namibia has a long tradition of using small planes with something like 200 strips, but heli's are still kind of new.
Let us hope that common sense is used. From what I read the Pilot already displayed a lot of common sense and responsibility.
