Some of the story doesn't really make much sense. Consistent pattern of break ups on impact does not suggest ad hoc bashing, cutting and general bodging to make structurally crucial parts fit. Also, the implication that the computer design process is at fault seems somewhat weak considering that process was developed for the 777 to achieve Early ETOPS out of the box. So far I have no reason to believe that any incidents are related to this issue.
No doubt there were QA failures, as there are in any organisation from time to time. The question for me is was Boeing's response appropriate and is there a significant risk?
