Dont be so sure. I spoke to my sources and they said that their opinion is that is a case of Spatial Disorientation and that Andy got a case of the "leans".
ATC tracking seems to back up their theories from what I am told but time will tell. I knew Andy and would be the last to say its pilot error, but I also trust my sources and they do accident investigation as a business.
I hope your theory is right but lets wait and see. One of us should be on the right track.
