I’m certainly not prepared to just throw my hands in the air and say “this was unsurvivable”. In fact, I put to any professional 737MAX pilot: if you studied the Lion Air preliminary report, you should have been well prepared for this event - it should not have been startle factor at all. If, in fact, you didn’t study the report and arm-chair fly it so as to be so-prepared, then maybe this isn’t the job for you.
I'd delete the maybe. In this industry it's what you don't know you don't know that'll come out and bite you. Seeking knowledge beyond the training provided can provide that last line of defense to prevent catastrophe.
