When they did the same test on the B727 the wings nearly met over the hull before they snapped, then it could be heard all over the airfield!
Did the A380 pass this test first time round?
We are in danger of being somewhat blinkered here, new material, a different picture altogether, not at all reasonable to compare the visual image of the 787 wing stress test with wings not constructed from the same material or to the same design.
