RockSim simulations, alternative motor choice for USLI

[Sam]

Check out the google group file "RockSim001". I show how I've
redesigned the rocket with a J1299N motor instead of the J1999N motor.
This is just a proposed alternative to our original design, but it
does have many benefits over the original. I also explain in the file
why this rocket design is a better choice. I'll try to get a rocksim
file of the design for those who were at the meeting to download the
demo version of rocksim. I'll also post something comparing the J1999N
motor with the J1299N motor.

Thanks and give feedback if you have any,
Sam
