#### Comparison with OpenRocket
This was our first launch using [OpenRocket](http://openrocket.sourceforge.net/) as our primary pre-launch simulation engine. Here we compare our recorded acceleration to the simulation. On the whole it did quite well. We suspect that the thrust curve that it had on file for our engine was not very accurate (or at least our motor deviated from it).
