you can only make so many systems redundant before the weight increase and lower capacity outweighs any potential risk of systems failing, or this is how it seemed to me when i compared cargo carriers to other aircraft. you need constant dedicated maintenance and regular troubleshooting, i don't understand how more ptoblems like this haven't already occured. there is only so much you can do without a reliable pilot to disable anything causing problems. and having seen firsthand the problem solving methods and goto solutions for maintainers, everytime a plane lands successfully it's a miracle
