Cool - it say's it's computationally expensive, though, so unless you and the rest of the JT team decide to use some kind of physics coprocessor, I vote for simple and easy.
By the way, is JT going to utilize or support any physics coprocessors like
PhysX? I don't know the details of the API, but perhaps one of these could take the load off the CPU(s) when it comes to flight modelling and projectile motion.
