This post is to give a little hope.
Recently I ran over a company in Tanzania called Renair Ltd. based in Mwanza. Their fleet consists of a Cessna 310, a Piper Aztec and two Piper Cherokee Six aircraft. From a low-timer pilot point of view the company might be interesting as they claim not to rely fully on tourism but having a massive part of flying done for mining companies. Which maybe will not be afected so deeply by this downturn.
They do pretty simpatic routes for tourists: Serengeti, Lake Manyara, Ngorongoro Crater, Tarangire National Park, Ngombe Stream National Park, Rubondo National Park and so on.
Might be worth giving a try. I didn't write them yet, so I know nothing about their requirements, but if I find out or you might know something about them feel free to share it with me.
