Re: Making bricks fly
"[..] if the pilot for whatever reason manoeuvres the aircraft hard, generating an angle of attack close to the stall angle of around 14°, the previously neutral engine nacelle generates lift. A lift which is felt by the aircraft as a pitch up moment (as its ahead of the CG line), now stronger than on the 737NG. This destabilizes the MAX in pitch at higher Angles Of Attack (AOA). The most difficult situation is when the manoeuvre has a high pitch ratio. The aircraft’s inertia can then provoke an over-swing into stall AOA."

This is why I mentioned the Sopwith Camel comparison, as it too had the tendency to fly its pilot into the ground when pushed towards certain points. Imagine a pilot pulling a bit more than usual on the yoke during take-off, causing the AoA to hit the pre-programmed limit, or turbulent weather destabilising the plane and causing lift or downdraft events on the nacelles. And that's all with MCAS working 'as designed'.
I did not need to 'invent' anything here. We have all seen the two fatal cases and the dozens of near-misses. The 737-MAX has wildly different aerodynamics (the way the airplane behaves under different conditions), which disrupt the stable platform of the previous 737 generations.
