“That’s why people say the fault is that only one sensor was used. If the sensor fails, the plane doesn’t know what to do, so defaults to stabilizing the stall.

The pilots didn’t know about the system, so didn’t know how to turn it off.”

Yep, and you paid extra for a feature that would detect the bad sensor, correct?

Bizarre that pilots didn’t know how to turn off an autopilot system that they knew was mishandling the plane.

They didn't know that the system was there. Boeing didn't include it in the MAX documentation.

MCAS is not an autopilot system. MCAS is on when he autopilot is turned off (pilots are manually flying the aircraft) and the flaps are up.
