There is no evidence whatsoever of airworthiness contributing to this crash – they were very close in while apparently in sufficient control to be changing waypoint and turning right – the final evasive manouevre seemed appropriate to sudden awareness of the ground etc with the a/c seemingly having started to respond to the large control demands – the attitude on impact seemed consistent with an a/c having been in a level attitude until these last inputs – the engines were found with matched power which would surely be unlikely if they had had any kind of control problems anytime in the last leg from waypoint change to impact– the track from waypoint change to impact was consistent with the course setting on the handling pilot's HorizSitInd which was the best approach towards that LZ. All this with altimeters set for a landing at the elev of that LZ. And with an exercise call sign. Etc. etc. Think about it.
