68 <p><strong>OpenRocket</strong> is an free, fully featured model
69 rocket simulator that allows you to design and simulate your
70 rockets before actually building and flying them.</p>
71 <p>OpenRocket features a full six-degree-of-freedom simulation,
72 realistic wind modeling, a multitude of different components
73 including free-form fins and canted fins, clustering and
74 staging. Read more about its <a href="features.html">features
75 and see screenshots</a>.
77 <p>OpenRocket is an Open Source project licensed under the
78 <a href="license.html">GNU GPL</a>. This means that the
79 software is free to use for whatever purposes, and the source
80 code is also available for studying and extending.
82 <p>OpenRocket needs help to become even better. Implementing
83 features, writing documentation and creating example designs are
84 just a few ways of helping. If you are interested in helping
85 make OpenRocket the best rocket simulator out there, please
