...and then all the parts (not the assembled fuse, or an entire wing) are shipped to washington for assembly.
Most of the parts involved can be shipped using existing means. Doing the interior in Washington means that the aircraft does not need to move between assembly and delivery (which, by the way makes sense)
Check out that Times article. Those logistical problems with the A-380 are quite impressive. They are building the whole darn wing in Wales, and then relying on custom transports to get the wing to Toulouse. Then they have to get the Hamburg plant runway extended so they can fly the planes there to do the interior.
These aren't subcontractors either: these are Airbus plants. Why not have it all centrally located, or at least the final assembly? Well, that's not how state-subsidized business works in Europe, now is it?
I'm not saying they won't overcome those obstacles; of course they will. But it's a classic example of ass-backwards business made to satisfy government interests instead of market needs, and complicating design in the process. You want a socialist government? Great, just do it right, and stop aping your american friends by feeding EADS.
