Air Tanzania has been a terrible one for the government, they have been without planes for many months now, and the only 2 flying are wet lease. I think Air Tanzania is dead time ago, but they keep the thing open to keep pleasing some people, but I don't really see any viable solution to it, the money needed to invest and the competition will make it a money losing airline for years before, and only maybe, start sustaining itself.
Another question is, Will Fastjet survive without Kikwete in the govertment?? I know there's an investigation going on due to unpayed taxes and too many rumours about money laundry using Fastjet by family and friends. So we will see what happen next, but it does not look good also.
