Whatever else, the aircraft left them with no real options to stop APART from closing the T/L (if that was the case) and that to me is WRONG, be it Boeing/Airbus/Embraer/Tupolev or whoever - WRONG. Plain and simple. Indeed, if Boeing have now gone that way, then I think they are WRONG too and I would not be surprised if folk are now looking rather carefully at what they have 'created'.
Forgive me if I have missed it in previous explanations - IF there had been those unlikely multiple failures in the sensors and with No2 T/L actually at IDLE but indicating CLB, what could the crew do to deploy the ground spoilers?
