It's not poor design or construction - it's basic physics.
Exactly. It has break somewhere. Otherwise it would be a tank. 757's buckle behind the nose gear when the nose is slammed on the ground. 767's buckle farther back. If they were built so they never buckled the plane would be too heavy to takeoff.
