Lighter planes means less fuel, means less money and, hopefully, lower ticket prices. Carbon fiber reinforcements are a major part of this plan; both Boeing's latest bird and the double-decker Airbus make liberal use of the light and strong composite. However, they're not without their own dangers; minute amounts of water can get into the carbon fibers, which then form ice at high altitude, damaging the fiber structures. This sort of miniature damage is -- unlike aluminum versions -- very difficult to spot. Embarrassingly, the engineers' best bet to detect the r
