I think this is as big technology step as when ship-building moved from wood to steel. This will revolutionize the industry and change the rules of the game. Congratulations to Boeing for taking the lead.

This is the difference between what Airbus is doing with the 380 tail cone and the 787. Every process before this is now stone age technology.
Good point of about the difference between the A380 tail cone layup sequence, and what the 787 is doing. Boeing can now optimise the layup sequence, for applied loads, stress concentrations etc., therefore creating a lighter weight design. This differs significantly from the way it is done in other places.

Yeah, I've seen this video before and the link to the Flight International article that had the video was posted here, but I could never get that video to play right -- always stopping and jerking. This one played well. Thanks!
We produced the largest, high-strength, fatigue-resistant upper and lower wing skins ever made.
We manufactured the largest, most damage-tolerant fuselage sheet ever created.
And we engineered new multi-material lockbolts for the assembly of the A380’s center wing box as well as the largest ever wing spar and new landing gear forgings to hold up under the pounding of a lifetime of takeoffs and landings.
This parts couldnt be made with same effect of composites. Even the 787 isnt fully made of composites(AFAIK 63%) and i doubt future aircrafts will be 100% composite.

Quoting AutoThrust (Reply 11): Oh cmon please come down from you hype. Dont let us forget the A380 has the biggest composite centre wingbox ever made and about al-alloys wich in your eyes are stone age technology:
Calm down, this is about fuselage construction, not wing boxes, and not what Airbus is doing.
There has been much debate about the A-380 tailcone, and how it is made. It does not need to be made like this and it isnt. That was my only point.
Also, "stone age" referred to previous CFRP layup methods, not things like robotic welding of advanced alloys, while impressive, are just not relevant to this discussion.
