Old Time,
I can understand your concern for conjecture but quite frankly, I am sure many of the newbies are equally concerned at the quality of information coming from professionals.
For instance, isnt it clear that this control tower uses a military radar system to guide planes in during low visibility approaches? If so, why all the comments on guidance systems that could not have been used.
Also, I have asked twice for comments on the lack of broken turbine components given the crushed housing on the port engine - the only comments were pedantic ones, criticizing the terminology that was used.
Well, was the engine under power when it hit the ground or not?
Finally, it is very apparent that visibility was 400 meters or more - thus, how could the crew not see the ground for several miles during the approach - just as the AC was witnessed from the ground.
Thus, in the absence of the experts to determine (in general) what happened, there is nothing else to do but offer conjecture.
