    This version has a bug in the code: 'set throttle to 0' just above 'break' at the end of the While loop should be just below (outside) the While loop.

    Not directly related to this demo craft and code: in the code i use 'While stage fuel > 0' to make a stage do what i think it is supposed to do until its fuel runs out. Seems like a sensible thing and works well for the first stage (TWR limiter), but does not work for the second stage: the While loop is skipped.
    The workaround i found is to use 'fuel AllStages' instead of 'fuel Stage' for the 2nd stage and within the loop check for fuel AllStages < 0.001 and break out of the loop if true. Without that check the loop never ends. Also this only works because it is a 2 stage rocket...
