65 <p><strong>OpenRocket</strong> is an free, fully featured model
66 rocket simulator that allows you to design and simulate your
67 rockets before actually building and flying them.</p>
68 <p>OpenRocket features a full six-degree-of-freedom simulation,
69 realistic wind modeling, a multitude of different components
70 including free-form fins and canted fins, clustering and
71 staging. Read more about its <a href="features.html">features
