The most recent variant of the 737 is a debacle, one that Boeing will carry the burden for years to come. It’s predecessor, albeit another cut & paste job, isn’t. Its not without its limitations however fundamentally it remains a basic aeroplane that rarely leaves you in a state of overwhelming WTF. The reason why this aircraft crashed was that three people let it crash. One of the basics of flying is airspeed. This accident was a nonsense and remains nothing more than a lesson in poor airmanship & monitoring.
