    Military Design Standards

    Hi guys :) I was sure that it had been brought up here before but I just couldnt find it using the search tools (so maybe it hasnt been mentioned). I'd like to know what you all think about crescent wings; how they compare to elliptical wings and/or your typical rectangular wing. I'd thought...
