One question I have: on Boeing how easy is it to just jump down to secondary law to give up some of the flight envelope protections. Can that be switched manually? How exactly does that look?

If you know computer is getting garbage data / plane acting in an unusual way, you can dial things back. These planes and their engines are so reliable and maintenance is usually so good that it seems you could fall back to closer to direct law flying (power setting / pitch / etc) and at least keep plane out of the drink / gain some altitude.
