I think crash investigators have to experience worse things than a CVR- including body parts etc. So I would not be scared for them. Police etc see just as bad.
The crash is a classic stall on take off with unknown cause (as yet). Note a couple of things- the idea that the climb angle was the result of excessive enthusiasm in leaving the
MANPAD threat envelope is pretty silly. The pitch angle and airspeed bleed would have been terrifyingly obvious and would have totally occupied crew efforts.
Also note the left wing stalls first followed by a right hand roll. Whether the latter was due to a control input is not clear but as the aircraft descends and gains speed the crew
definitely have aileron authority and roll it level just before impact.
So clearly the crew had working aileron linkages and used them but (a) whether the elevator/HS link was disabled or (b) it was functional but ineffective due to a rear CofG will have to await investigation.
It's obvious that no professionally trained crew would allow their aircraft to get into
such a dangerous attitude and airspeed configuration unless something broke.
In other words, let's rule out the usual great finger pointed at pilot error.
