    Excellent !

    The elliptic wing planform...actually a "double ellipse" was designed to minimise induced (lift dependent) drag; the skewing of the ellipse was to get the local wing centre of pressure onto the unswept main spar ... this being a good thing for the structural design. This was based on the work of the German aerodynamicist Ludwig Prandtl whose work was published in 1934 just in time to contrbute to the Spitfire....nice case of international collaboration eh?
