Earlier quoted context omitted.
True but I have a feeling it might be designed to rip off in this situation. I'm more surprised the wing rupture didn't cause a fire/explosion because this is where most of the fuel is stored.
I seriously, seriously doubt it. The wings are so utterly critical to flight I can’t possibly imagine any situation they’d be engineered to snap off under. Further, that’s where the fuel is and any crash involving a wing rupture is dramatically more dangerous given the risk of fire. Hell even in a crash landing like this you want the plane to stay upright and stable.
They know how much peak load is supposed to be for the airframe, then they go well beyond it to see how the plane fails. Generally you want the wings to break not the fuselage.
You can in a lot of situations land a plane with 1.5 wings. But once the spine cracks you’re just a ballistic object.
