content: The faulty MCAS software was created by Americans. What happened is they fired many senior engineers because they were expensive. But those graybeards were expensive because they had learned how to not kill customers the hard way: by killing customers and dealing with the aftermath. It reminds me of AT&T Wireless, which completely and permanently destroyed itself in a software fiasco. They needed to upgrade their software to support number portability. They did this by turning on the new software at the deadline and throwing away the old software. When the deadline came the new software could not process new customer sign ups. They had to sell out to Cingular, who now does business under their brand name. It was basically a commercial version of the Obamacare website.
