Last month I looked at a simple ’rocket’ represented by a Visual Basic 6 control. While it worked, it did have one or two limitations. First, there was the somewhat rectangular appearance to the control. Let’s face it, most rockets are not square. Secondly, the Earth’s gravity was treated as being constant. Of course, the strength of the Earth’s gravity varies with distance from its centre.
