I would trust the opinion of someone trained in the studying air accidents for the FAA over someone studying A&P I assume this is aviation?

could you put in full words what you are studying please? I am pretty sure that is not specifically related to the study of air accidents.At least A friend of mine went to Emery Riddle and studied accident specifically and recvied a BA in it.
Have you seen the FAA investigation reports on this accident to allow you dispute with reputable evidence.Which to satisfy me would be a person with many years experience investigating air accidents.
Also do not forget that this plane struck the ground at a very high rate of speed much higher most likely than any previous crash involving an aircraft of this size.
If one takes into consideration the scattering effects of most air accidents at much lower speeds they tend to scatter wreckage fairly far so it seems logical to me for an aircraft striking the ground at a high rate of speed and diving for the ground (where as in most crashes the crew is trying to avoid this) it makes sense for most of the wreckage to go into the ground.
Of course it is always possible that one of TLAMs doubles might have managed to brain wash me maybe he did and I don't remember it because I am now a manchurian candidate.
