That was my point. The lack of AoA redundancy was an egregious design flaw that no software could have fixed. A design with a simple but catastrophic & easily foreseeable error isn't a good or even OK design overall. If you make a suspension bridge missing one of the towers, or lacking sufficient cable strength causing it to collapse, your bridge design is terrible, even if everything else you did was flawless. Maybe the engineers had excuses, were rushed by management etc., but their design was still insane.
