The Boeing 737 MAX When Humans and Technology Don't Mix
summary
Boeing fits much larger engines onto a 1967 airframe, shifting lift forward and causing nose-up tendency, then hides a software fix called MCAS that forces nose-down using just one angle of attack sensor. Two flights, Lion Air and Ethiopian, suffer erroneous AOA readings, 346 deaths and $20 billion USD in losses follow, the fleet grounds for 20 months, and pilots lack training or a usable manual override so they cannot overcome the runaway trim. single point of failure
