JD-EE
PJ2 made a comment I hoped to elicit, "DO NOTHING was the correct response and that is the action which would have "prevented" the loss of control."
I'm not sure Do Nothing was a valid course of action either. As I understand it, there is nothing automatic to keep the machine right side up in roll while in Alt2 Law. The pilot has to fly the wing roll attitude.
If it was in lateral trim, probably no big deal to fly it in roll direct law, just be gentle but firm.
Out of lateral trim, it would be a complete handful-until you balanced it out with rudder trim.
