This is the Hawker 900 XPi commissioned by Frans Erasmus, the then Chief Pilot of National Airways Corporations. This particular one I did twice in fact. The cabin crew on this particular jet on seeing what I was doing, commissioned it for the then owner of the aircraft himself to take back to him.
I then did it again for Frans, the original commissioner of the work, to add to the collection on his office wall. I have always thought that the Hawker jets were a nice shape to the eye.
