Almost resembles a Burnelli wing design - not the most efficient things and you get some crazies when it comes to dealing with them, but they sure look cool and tend to fly nice.
He did some impressive, futuristic designs for sure. I think from a designers perspective at least, we really would want to be designing them to be underwater, the density changes dramatically and the gravity is lower of sorts. I did a manta ray chuck glider in this kind of a format, added fins and the rest, it was absolutely hopeless of a flying thing, it was an anti flying glider, even though we know the manta ray swims perfectly in the water. I can go on with ground effects based planes and they become highly unstable when they are no longer using ground effects to stay aloft, open air like a regular plane.
