747 wing near breaking point in static test
This photograph was taken just before the wing of the Boeing 747 airframe used in static structural test broke at 116 per cent of the ultimate design load. This is 174 per cent of the design limit load, which is the maximum load the 710,000-pound super-jet is expected to encounter in normal airline operations. The wings bent up 29 feet at the tips before breaking. The wing-destruction test climaxed a year-long "torture test." Test results exceeded original engineering predictions and proved both the 747's basic wing strength and the airplane's capacity for future growth. - Boeing photograph
