When I read the stories of people having the power steering go out on a Tesla, I think, "Man, you haven't lived until you've flown a 737 in manual reversion mode..."
Luckily, we only do manual reversion as a training exercise now instead of during PC checks with an overzealous check airman.
A few years back, we all finished our PC's (yeah... .back when we
did PC's...) early and had a bunch of extra time. Check airman set me up to do a manual reversion single engine ILS down to Cat II with no HUD, and no flight director. There were no survivors.
