>Are you suggesting they build the entire fuselage as one piece and "glue it all together"?

That's basically how they build ships. The glue is just a little hotter.

It seems doable but QC would probably be a nightmare and it wouldn't be very repairable adding up to it not being an economically sane choice.

Edit: Since apparently this has to be said, they weld ships together creating what is in effect one single piece assembly. The point is that while the techniques for joining fibrous materials are very different, large single piece structures that flex and bow are fairly well understood and there's no reason you couldn't create one out of carbon fiber if doing so penciled out.

IIRC a major rationale behind the 787 design is to allow sections to be manufactured complete with wiring harness etc in different locations and then shipped for final assembly. You can build really big parts (check out Janicki) but for this application probably not desirable.

They definitely stich sections of hull together to make all but the smallest ships.

Their point is that the hull sections are welded, becoming one single solid piece. Ship hulls do not have gaps.
