Call me skeptical of this....very skeptical. Torsional failure of the
SKIN between front and aft spars in the stub wing area? Really? So
what? I suspect something is missing in the translation, but I'm not
going to swallow that until I see this analysis, and maybe not even
then. Typical airplane structure is the main spar carries the weight,
and the aft spar prevents the wing from folding aft. I don't see much
in the way of torsion there, and they're calling it "the weakest part of
the airplane"? So what? Oh, and it's never happened before? I'm even
more skeptical.
Let's not get all wound up about this.....
