It would have to be something very serious to lose all electrical systems. the 330 is a FBW airfract meaning it uses computers to fly instead of pilots having actual control. 4 electrical systems and the hydraulics would have had to all fail for the pilots to lose control.

This has to be something structual that happened durring the storm. Its unlikely that lightening caused this but there isnt alot of other options. Yes strikes happen frequently, however when they do if over land, emergency landing procedures are taken.

That's a little misleading. Just because there are 4 backup genarators doesn't mean they have full quadruple redundancy in the electrical system. It's still possible 1 system failure could bring the plane down, although that is equally unlikely as any system that is critical enough that if lost, will result in losing the plane, likely has at least one backup.

But if say you lose the transmitters from the autopilot/control stick to the rudder, then all the backup generators in the world won't help you.
