Hi!
I think you mean Fly540. The are based in NBO Jomo Kenyatta airport, and are growing. I flew on them as a pax, and know one of their cabin crew. Very nice.
I have heard good stuff about them from a pilot point of view, such as great pay for a turboprop operator. They are getting new planes, including CRJs ("The Flying Carrot"). I have heard they are one of the better places to fly for in East Africa.
