There were no simulators to train pilots (only 4 delivered up to now, vs. 376 planes delivered! -- by the way, the value of all MAX orders, including these still not delivered, is around 600 billion with a b dollars!) and if I'd guess the simulators can't simulate the plane behavior when MCAS is off. Because the selling point is "MAX behaves the same as the old one." Which is just not true.
