RetiredBA -- No worries. I'm pretty pedantic myself about such things but tried to use terms a non-pilot would understand best. I thought he was seeking some kind of plausible explanation for this tragedy. Indeed, everyone here is.
The LOC possibility sounds plausible. I was looking at it from an instruments pov because that's my specialist field. I still think the static could have been a factor in disorienting the pilot if it was in the wing section. Would probably need a wind tunnel test and that isn't going to happen. Could make a good final-year undergrad study in aeronautical department. Lots of meat in there and historical interest.
Coming back to LOC, it is plausible. For me the least plausible explanation is that this particular pilot just screwed-up. It's possible, but less likely than other things. We can't turn the clock back. We can try to learn from any deficiencies. We can help all those involved to get closure and move on with their lives.
