There was a project for the Saab AS-36,does this related?

Interesting, I hadn't seen that SAAB concept before.

Hispano-Suiza HS.50, a proposed fighter for Spain designed by Dewoitine.

Really nice, late or mid 30s design?

The latter. You can see the strong similarities with the Dewoitine D.520

In the mid 30's, Howard Hughes tried (unsuccesfully) to sell his H-1 Racer to the Army Air Corps.

Easy to see why they refused it; the visibility on that thing is atrocious; takeoff or landing would be a nightmare. It's much worse than the Corsair, which had nicknames like "Hose nose" and "ensign eliminator."

This was a real design - in fact it was just one of many Supersonic Business Jet designs that suddenly sprang up and became popular in the middle of the last decade as if for some reason they decided supersonic travel was going to become the next Dot Com rush. And like those others, this aircraft exists only as Vaporware - SAI (Supersonic Aircraft Industries) sprang up from nowhere, attempted to get funding and backers, failed to do so and quietly sank back into the woodwork without a trace, with even their website evaporating. Which made it extremely hard to find references (though given that this existed as Vaporware in the first place I suppose it doesn't matter to begin with). That said, SAI somehow found the funds to farm out design of the QSST (which rather ended up being one of the more daring designs) to none other than Lockheed Martin, which did get a wind tunnel model up, so this design actually is proven to be workable and also means the QSST just about got the farthest in development by default.

Hopefully I'll be able to do some other supersonic bizjets soon - the Aerion SBJ (imagine an F-104 blown up until the fuselage can hold people), newcomer Hypermach, and perhaps the two most serious designs thus far, the S-21, a collaboration between Gulfstream and Sukhio that got killed when Gulfstream gave that order, and the Tupolev Tu-444, basically a Tu-144 shrunk down to bizjet proportions (even keeping the same cockpit and nose section).

Impressive, it manages to be both ugly and appealing at the same time. Given it's rather complicated shape it might be worth it to use some heavier shading to better show it.

I'm having hard time believing that Burt Rutan wasn't involved in the design... looks so much like a few of his things...
