Sound familiar?:
The amount of failures is unprecedented,” said Richard Woodward, a fellow Qantas A380 pilot who has spoken to all five pilots. There is probably a one in 100 million chance to have all that go wrong.”
But it did.
Solution:
What we have got to ensure is that systems are separated so that no single point of failure can damage a system completely, Woodward said. In this situation the wiring in the leading edge of the wing was cut. That lost multiple systems.

kudos to these guys….
they understood the system well enough to land it successfully despite the challenges….some pretty good thinking was going on and the training is obviously excellent.
The design of the aircraft should be carried out in such a way that even if a “less than perfect” day is being had by the crews, it is still possible to for a happy outcome to occur
We should be aiming for both!
