Flexibility Doesn't Give Strength
I am a professional structural engineer and it is a pity that what I understand to be an often repeated myth has been repeated here again. Perhaps another structural engineer will correct me if I am wrong but wings would not be weaker if they were less flexible. The idea that something has to be resilient or flexible otherwise it would break is true for a link between much stronger items that cannot be restrained (like flexible sealant between slabs of concrete) but it is not true of a wing or a skyscraper. A skyscraper may be tall and slender to look impressive. A wing is long and slender for aerodynamic reasons. In both cases these are constraints that make them more difficult for the structural engineer to ensure that they are adequately strong.
