I think Curt was trying to point out a way you could make something work from nasal without getting into core code. > The locate tower with a mouse click suggested by Gijs is closer > to the mark (though the link to the script doesn't work for me).

There is no existing support? Have you looked at the Fly-by view? It pans, rotates and moves itself to follow the aircraft already. It might be exactly what you're looking for if you were to adjust it so the moves weren't so random, its a bit disorienting when it jumps from side to side and above and below the model. If it always stayed at ground level and to the same side of the aircraft when moving it might make a nice automatic R/C view.
