// A "max" without MCAS handles very differently to a 737 NG, but it's still perfectly flyable. //
Not really. Because Boeing were a decade late in developing a new more fuel efficient plane, they decided instead to cut corners by modifying the 737. Unfortunately, when the airframe was extended to Max, and the new more efficient engines mounted, the ground clearance was too small. So Boeing decided to attach the wings higher, which totally changed the aerodynamics of the plane, making it much more difficult to fly. MCAS was a sticking plaster to try to mend the flawed design. MCAS was supposed to aid the pilots to the effect that they would not need costly retraining. But it was poorly implemented, and the regulator, the FFA were too cosy to Being to properly do their job, and approved the 737 on a nod. Then the crashes started.
