Statistically, is it in fact more or less just as probable that other causes remain to be considered - however apparently unlikely - i.e. pilot incapacity, sabotage, etc?
With the scant information available to the public at this point....Commonsense alone indicates considering all possible causes to be the bett4er course.
Watching video's taken from several perspectives does tend to point one's interest in one direction but absent more definitive information pointing a finger at a cause at this time is pure speculation.
