This is an excellent article, the first one I have seen that gets to the heart of the mechanical challenges involved. Long as the article is, I recommend it because it shows how revolutionary this new building process could be; it's a big change from bolting aluminum!
One of the things that emerges is the sense that all their other lines could see tweaking in terms of materials and production techniques. There's already been talk of making the 777 cheaper to build (a great way to head off competition from the A350), but it will be fascinating to see how this technology could be applied to the other lines, such as the 747ADV.
It is not enough to be rude; one must also be incorrect.
