Clear Prop, if we go back to the first two pages, the various eye witness accounts (which were not dashboard cam) mentioned pitch angle. This discussion hasn't just been about that vivid but incomplete video. Your point on perspective is well made.
deSitter:
Don't know if this has been mentioned, but in the dashcam video, the aircraft is already recovering from what appears to be a significant right bank when it comes into view. This becomes a left bank, then another catastrophic right bank and total stall.
You use two words there that I find hard to support from the video clip available.
1) "Significant" right bank? We don't know how much it was, the plane is just coming into view.
2) Why is that roll "catastrophic," as opposed to any other part of the departure, most of which is not on that film clip?
While the FDR should shed light on the sequence of control and attitude relationships, and AoA, that last right roll may have been related to post stall behavior, or it may be related to a last attempt by the crew to get the nose down and restore control.
I've seen both points presented with decent reasoning, and cannot rule either out based on the limited evidence available.
