It would appear that pressing said two buttons would take the very system that makes the MAX certifiable at all, off line. That sure sounds a bit weird if one asks me. I don't see any logic in the claim that there was no incident. Actually each time those buttons had to be pushed during a commercial flight, it was an incident, since it took the plane into an uncertifiable state. How many times were those buttons actually pressed by pilots transforming the plane into a non-certifiable aircraft while in commercial flight? Anyway, the speculation now is grounding for six to nine months notwithstanding all the brave pronouncements.
