At the risk of annoyance, a number of eyewitnesses and other videos appear to be indicating that the departure was not typical (standard?) for that site. Legal, within regulations, etc, etc, but possibly not normal. For the lack of any other evidence I still wonder if there might have been something about the height of the departure that offers a clue to what subsequently went wrong.
The probable causes now remain:
Part of the TR assembly failed and departed flight.
Something struck the tail area causing a catastrophic failure.
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?
