Thank you, Peter, for the translation of the A330 accident.  One point
comes to mind:  If Vmc is the minimum speed at which directional control
can be maintained when one engine is developing zero thrust, the other
is developing full thrust and the CG is at its most rearward limit [the
configuration of the A330], how was directional control maintained
between 18-28 kts below Vmc?
