Boeing's new 787 wings: Amazingly bendy

An anonymous reader writes: Boeing is making the wings of its new 787 out of carbon fiber instead of metal. That means the wings are so strong and flexible that they could bend upwards and touch above the fuselage — or come close. The company is expected to deliver the first 787 to All Nippon Airlines in May 2008. From Aviation Week:

Boeing has completed static testing of a three-quarter wingbox, but engineers are still considering whether to limit testing of the full wing to a 150% load limit held for 3 sec. of to continue bending it to see when it breaks. "There's a raging debate within the engineering team to see if we should break it or not," says [787 General Manager Mike] Bair.
