    Derrick, where did you get this, much of this seems wrong to me.
    
    all flying things follow a "ballistic" trajectory, plus or minus
    lift.  there is no "gravity turn trajectory".
    
    my model and high power rockets are unguided so mostly fly straight up.
    even so, they are on a ballistic trajectory which is pretty easily
    calculated a number of different ways.  but not commonly with a Taylor series.
    
    the shuttle is steered eastward intentionally, to get an extra 1000 MPH
    for "free" from the earth's rotation.  most everything else launched from
    Kennedy is sent the same way.
    
    but the intentional steering has nothing to do with weight of propellant
    or max Q.
