It defies common sense at that time either the captain or the engineer on board would have been tinkering with anything.
I disagree. They were not overly concerned with TRW's as they had requested and were given a deviation around them. The weather was not a major obstacle as many other aircraft had passed through the same area.
It is starting to look like they were "troubleshooting" the faulty FAC and got much more than they bargained for. Once more details are released, I would not be surprised to find out that the weather played no part in this accident.
