Parabollic path in flash?????

Hi...guys....
I am struck up in my game project. Please can you let me know how to generate a parabollic motion of a missile along the perspective view(z axis) in flash.

thanks,

From a stright on angle it would just invole an enlargement of the missile as it gets closer and a slight motion up then down to the impact point. Other than that, it would depend on your 3d engine that you're using.
