I would substitute "propaganda" with "evidence".
Not even the MAX simulators could simulate the MCAS fatal events - so it could only be done as a live drill.
Interesting re simulators not having capability to duplicate stabilizer aero forces as a function of speed and elevator and stabilizer position
Over 40 years ago, used a heavy duty magnetic clutch - basically a magnetic disc/motor with metal particles in oil surrounded by a dc winding to evaluate torque versus speed for large drillmotors and getting a torque versus speed curve ( mostly linear ) and then a simple calc to get horsepower.
Thus, IMHO a relativively simple device could be used to duplicate aero loads as a simple computed function resulting from elevator position and stabilizer position and airspeed ( based on actual flight data ) and then tied to the trim wheel- cable system equivalent in the simulator. Drive it backwards is also possible. But of course it might cost a few thousand dollars per simiulator plus flight test data costs.
against a million $$ per plane cost for not doing it ??
By god we will save a million dollars no matter how many
Billions and a few hundred lives it costs.
