Thanks very much, I have tried this and I think that with a little tweaking it
will meet all of my requirements for both test scenes, and the animation as
well.

I think I will retain the use of a spline as well, as it will allow me to have
several shells in the air at the same time, especially with a shell flight time
of ~24 seconds.

Many thanks,
