Stage two is transforming the plans into the full scale model.

This ship has proved to be  deceptively tricky in nailing down the shapes. At first glance it looks like a collection of basically flat panels. but I think MC Escher had a hand in designing the nose  of this one! It took three attempts to get the air intake opening looking close to the original, but I just couldn't make the angles work as depicted in Chris's illustration. His appears to be a square shape when viewed front on, but I could only make the angles work by having it wider at top than bottom.
