I assume this is a spaceplane that's capable of SSTO, but where are the wings? The idea of preventing overheat during re-entry is that, you keep a 30-40 degrees or as high as possible AoA, and use the extra drag to slow down, just like the real world space shuttle. I think we need to start a new thread in the spacecraft exchange sub-forum to discuss these. I'll be posting my cargoship later there
