Re: PBS Frontline: Boeing's Fatal Flaw

Unfortunately too many pilots today do not know how to hand fly aircraft. The only thing that saves them is all the electronic automated systems they rely on. If a system fails, like MCAS, which was NOT properly engineered and they do not know about it and do not have the ability to disable it they...
