Salute!

The pilot analysis seemed fair to this old greybeard, especially the whine about not letting the pilots know about a new and significant system ( only when it goes rougue),

I cannot help but wonder how many $$$ Boeing saved or the carriers saved by not having some sim time training that demonstrated a rogue MCAS high alt or just after takeoff. They are all surely paying now, ya think?

I also do not unnerstan the bang-bang implementation versus a smooth stab input according to AoA. No need for a new computer, as a 1970's op amp (analog) could easily provide the control signals. Not everything with a "chip" is digital, with clock speeds, mux-bus protocols to deal with other systems, RAM and so forth.

For all who do not realize, but the original Viper quad redundant computers were no-kidding analog doofers with op-amps and both D-to-A and reverse chips and then voltage commands to the servo actuators.We had no internal clock speeds or delays. The chips worked literally at the speed of light thru the wires. We did not go fully digital for about 20 years
