Andreas,    (01)

        We make money by making aircraft that don't fall out of the sky,
not by simulating their performance (though obviously we make more if we
get that right too :-)). My views derive from the very practical problem
of getting bits of metal and plastic to fit together - think of a
numerically controlled milling machine as a sort of 3D plotter. That is
what, in this instance, I mean by behaviour.    (02)
