Don't normally comment on accidents and wont pretend to have any special
knowledge, but apart from the detached TRs, nobody seems to have mentioned the
bloody big hole in the side of the nacelle..
I mentioned about potentially spat blades with my original comment on the TR. But this could have come as a result of FOD as the jet carved its way through the treeline.
My thoughts are in agreement with another poster; if this damage pre-existed prior to impact, you would have expected smoke stains both aft and above the hole. Until the prelim report comes out and they replay the tapes, its all guesswork!
If the aircraft has impacted trees, I wouldnt be surprised if the TR had ripped itself off in the impact with the ground.
