I thought there were too many aircraft in the world today so Boeing and Airbus need to develop inovative technology to encourage airllines to replace their existing fleets. Since the Dreamer is mostly composite, it is 40% (??) lighter than a conventional aluminum plane and, therefore, burns a ton less fuel; right?
Composites have been around a long time and Airbus has used this in VS, and controll surfaces since the 80s. Many beleive these designs or the materials have casues a few tail snapping incidents so far, but the jury is still out, I supose.
Anyway, I guess Boeing will eventually figure this stuff out and make a ton of money in the future.
