Let us wait for the findings of blackbox and pilot information from an investigation team before starting to speculate the cause.
Not sure that I agree... I know a lot more about 777's as a result of these PPRuNe threads than I did a few days ago because of the theories proposed here. Questions have been raised that I, personally, didn't immediately have an answer to... until I went back to my manuals (or until one of the more knowledgeable forum members responded).
Albeit maddening, it is a learning process.. Unfortunately, some of us don't take on information as easily as others
Let's hope the FDR/CVR have the answers... but as someone already mentioned, it may not have what we are looking for. The FDR may tell us what was happening to the aircraft, but not necessarily why it was doing that. However, hopefully it should reduce the variables
Rgds.
