GlueBall:
I second what vilas said. Any transport category pilot will tell you it's complete BS to deduce an aviator's training record and knowledge from a few seconds of pixelated video of their demise filmed from half a mile away. That's what the investigation team exist for.
While its informative and useful for the community to speculate a little about "maybe it was a load shift", or "if you study the wingtips really closely from the very beginning of the clip, their motion suggests almost Phugoid motion which might imply they had no direct control over the aircraft at all", while we can drop these things into conversation, there are too many variables for anyone to make any specific statements about this incident, I will wait for the report to come out for that! No offence meant.
