If anybody knows how to streamline something, It's a toss-up between the Lockheed Skunkworks and Mother Nature. As far as I can tell, the Skunkworks ain't talking, and nature is right in front of you so just look at the body of a fish- or a bird for that matter. Both have cross-sections which are amazingly similar to post #3. Maybe I've oversimplified things a bit, but once again, you're not going supersonic.
