Weird. Definitely looks slow with a high angle of attack then into a stall. Not what you would expect in daytime VMC. Possibly one of the engines rolled back, got slow, then Vmc roll? Didn’t seem to snap over like you see on one of those though.
My first thought before seeing the video was a di&#ed up approach leading to an accelerated stall. Had the Kathmandu crash on my mind after seeing that episode of Air Disaster the other day. Clearly not the case here.
