On the NASA Shuttle Carrier Aircraft for the Space Shuttle the Orbiter Support Struts for both forward and aft location have now been modeled in 3D. I'll add the aerodynamic covers tonight. However, even with technical drawings, I think the aft struts need a little widening to make it look more like the real thing.
This is just a starter 3D model of the Boeing 747-100 Shuttle Carrier Aircraft. It's not going to be too complex. For the time being I'll just improve the fuselage, add basic landing gear, control surfaces and the supports for the Space Shuttle Orbiter. I'll model both N905NA (747-100) and N905NA (747-100SR). I also plan to create the original 'American Airlines' and the NASA liveries as textures.
