Boeing is only arguing this because if they say simulator training is necessary, then the plane must be recertified. Their executive MBA analyst and stock watcher types under no circumstances will tolerate recertification, therefore regardless of facts, their position must be that simulator training is not necessary. Even though it obviously is. Key point to observing this and everything else about this debacle is that Boeing has no concern whatsoever for safety, professionalism or lives, and is only interested in their own profit, executive bonuses, and stock dividend gains and will do absolutely anything to protect those, even though it inevitably is going to lead to another crash and more deaths. At which point they will again start by doing everything they can to blame the pilot and the culture of whatever country he hails from, as well as paying shills to post nonsense and attack pilots, engineers and others who question their narrative publicly.
