On the launch pad, the Alpha III stands as a great demonstration of the true basics of rocketry. It shows just how simple a safe rocket can be. Each component has a purpose, and you can leverage those against the principles of flight to show how this small, simple rocket actually utilizes everything that would make a much larger rocket safe and stable in flight.
