"What about the 332 and 725?"
I think that AH statement on Friday only referred to the H225. Not sure if there was a later one.
The SIN does seem very unequivocal. But leaving aside deliberate sabotage or wilful misconduct, something that can go wrong, will go wrong. An engineering / maintenance error may likely still lead to some change either procedural or component design, to ensure there could never be a repetition.
At least it sounds as if we will be hearing more sooner rather than later. This uncertainly and speculation (by us as much as anyone) is doing no good to the industry or the shattered confidence of our passengers.
