I was in Uganda when ViaUganda was operating. They had a 737 200 and did not last long.
From what I hear, SkyJet will not last long either. Spoke with an oke I know in Entebbe earlier who knows the guz there and he tells me they do have good financing from some group in Sudan (money laundering) so how long they want to support it is a big question. Once the bills really start coming due I think not long. They have some management that is full of lies, fancy promises, and hot air. The 767, if it ever were to come, is an old model that has been retired from the west, similar to the 737. Odds are it will not come.
