I don't know how this happened, but it strikes me that the HS broke at least at one point (don't know if it did broke at the other side also like at the left side or departed "only" in two pieces) and the VS is also lost, only the leading edge and the skin attached to the fuselage stay there (this point to vertical only acceleration/s, compare with flight 587). For me, the fuselage could not be badly damaged before, otherwise you don't have the leverage, also see engine pylon damage.
Edit: also someone pointed here to the long fuel line of the APU still there, that would probably not happen if the fuselage was compromised first.
