For the record, I think it's quite obvious what happened in the photo. My estimation would be something like this...
The text that's chopped off says "Wings slam into ground, flattening vegetation in two distinct shapes. Wing fuel tanks explode, disintegrate plane
and scatter debris. Momentum of impact and explosion throws debris and ejecta forward in traditional spray 'arc'".
Again, I'm not claiming it was an F16 that crashed there. It was seriously the first picture I found that was the right perspective.
As you pointed out in Part One, Joey, there are tell-tale signs left behind by kinetic energy with respect to direction.
In my interpretation of the photo, it is clearly left to right. In yours, roughly top to bottom (although that seems to me to have far too much debris
spray behind, and far too much to one side, but not the other).
Either way, the kinetic energy leaves evidence as to the nature of the crash. Yet with Shanksville there is virtually no evidence of kinetic energy
being transferred to the ground by a plane travelling at 40º.
As I showed in the OP, a plane at 40º will have MORE horizontal momentum than vertical, and roughly one-third of the length of the plane would be
transferring this momentum to the ground BEFORE the front edge of the wings reach it. Yet there is no evidence of this occuring...
The 'OS' seems instead to claim that the energy was transferred directly down, therefore seeing the majority of the pieces of the plane bury
themselves in the Shanksville soil...
