I haven't dug deeply into it, I've seen images showing crumpling at the
base of the nose cone, one image that appears to show a bend in the
mid-body of the airframe, another where it seems like the ship is
sitting on the engine compartment skirt, not the landing gear, etc.

Yes, things involving serious dynamics are hard to sort out
except in
flight test, and that just has to be allowed for.
