I probably used "zero torque" when thinking along the lines of what Cylcol had reported....but was talking about a generic event and not the one that happened to the PHI aircraft in particular.
My conjecture also would have to allow for the differences between shaft driven transmissions vice direct input drives. My thinking was more along the lines of a mechanical failure vice a digiital brain unit running amok. The main discussion was more along the lines of how the various digital brains interact.
