Operating in Africa (South Africa excluded) teaches you one thing very quickly… you are totally on your own. The key rule is not to trust anyone. Anyone remember the Hydro Air cargo 747 that crashed in Lagos after landing on a closed for maintenance runway? The controller cleared him to land and turned the runway and approach lights on for a runway covered in construction vehicles. A couple of years ago I was the first arrival into Lagos early one morning. We asked the tower for the weather and they said it was lovely weather. We went down to 200′ and had to go around due to no visual contact with thunderstorms all around and when we called them to notify them that we were going around all they wanted was for us to give them a weather report! Nairobi is not quite as bad as Lagos but it has a whole bag of other issues such as specific routes to fly on arrival and departure to avoid getting shot at by the natives!
