In one of my 1st year engineering classes we put together similar models in MATLAB Simulink. It was a lot of fun, and we gradually built up the model until it included the coriolis effect, and accounted for different air densities at different altitudes, all of which are important if you are firing an artillery round 20km. Our results matched up well with tabulated data from real rounds. The Wired article that doesn't even account for air resistance is a little disappointing.
