We do not have details of this anomaly, but I hope you understand that some situations must be simulated, flying into them is difficult, maybe not possible, or downright unsafe.

I don't know how much about planes do you know (I'm starting to feel not much since excessive, maintained pitch during flare didn't tell you anything). But the context explained here is rare and obviously more manageable than "one of three redundant sensors failed and an aircraft went out of the sky without giving the crew even a possibility to save their lives".

EDIT: Found new details. The pilot has to keep the excessive pitch although AWARE that he is stalling the aircraft.
