#1 RA wasn't working properly. It did not cause the crash, the pilots who are normally monitoring instruments caused the crash by not monitoring. I don't think Boeing has much to do with this crash. You can not make an aircraft so safe that the most incompetent crew in the world can fly it with no problems. Airbus may try to make pilots unable to screw up but I hope Boeing doesn't. Having final control of the aircraft and no computer overiding me has been wonderful in my career. I love Boeing products that let you overide anything that doesn't do what you want. I know this was a Boeing but nobody was flying it.
