From the developer:
RockSim is a computer program that allows you to design any size rocket, and then simulate its flight to see how high, and how fast it will fly. Even before you start building your creation, you'll find out if it is stable and safe to launch. Just image how much money you'll save by doing all your test flights on your computer!
