This thing of go flying in Africa, is also an utopia!
First, going to Africa does not work for everybody, fair enough trying to live the dream, but making insane decisions to achieve this is also another part of it!
Friend of mine works with insurance within aviation, and told me there are jobs there, but you do it on your own risk, as safety, bad maintained aircraft etc. claims many lives every year!
The only positive with bush flying that it might give you some long term connections, however short term - it is not going to give you to much.
To be honest heard better things about people who worked for Susi Air than!
