Screen Cap absolutely. Same experience from my end. The capt voice on the R/T might give a clue , but there is also the possibility of uncontrollable aircraft in the end due technical issue or CG shift , which they are looking at. But it is all to be proven . One last point since we are taking about past experiences: mine are that there is very rarely a single simple cause to an accident. Most are a combination of factors happening at the same time. I suspect the same here .
