Yes air sound I do believe that the Max will be safe. I don’t think Boeing could countenance another accident. I believe that Boeing engineers have produced solutions coupled with operational guidance which should of course have been in place at the start. Please believe that I am no defender of Boeing; the original service introduction was an absolute disgrace. You can look at the aftermath in two ways. A realisation that there is a moral responsibility to put it right. Plus an economical agenda. I believe that one has to have confidence in the aircraft now as further disasters are untenable.
