The shuttle's wings were replaced with inflatable airfoils featuring self-inflating valves in the leading edge to automatically retain rigidity.
The shuttle's bulky, durable landing gear were replaced with a lighter bicycle arrangement and wingtip skids. Finally, a towing mast was connected to the aircraft's prow to enable a mothership to thrust the glider aloft.
I based the model on Revell's Heinkel He 177 A-5, with parts from Italeri's OA-10A and F-14A. Inverting the wings (including the roots) and giving them the angled bend was the first challenge, followed by puttying all the gaps. The longest period of assembly was removing all the surface features to produce an “inflated skin” effect on the wings and polishing off the horribly molded straps on the cockpit blister.
For the paint scheme I made a first frustrating attempt at pre-shading, and after a half-dozen bouts of priming, painting, mourning, and sanding down to bare plastic, I finally like the results. I tried to create a 1930's Captain Proton effect for the entry, and I included a few nods to Martian sci-fi in the decal scheme.
