Long-term benefits could be a 15 to 20 percent reduction in total structural weight, a 7 to 15 percent improvement in fuel efficiency, and a resulting 4 to 8 percent reduction in direct operating cost -- the latter is more uncertain because manufacturing costs for composites and future fuel costs are very uncertain. European R&D efforts are extensive and continue to accelerate.
