The fuselage impacting 'flat' does not preclude any attitude up to flat impact, including nose up, as the 'tail' may have contacted first, destroying the tailcone and VS mounting hoops, releasing the fin from its forward mount. If there was rotational (radial) movement (not roll), that would explain the 'left' torsional component of the failure. Dragging the tail would slow horizontal velocity, derotate, and allow for a 'flat' aspect at contact (a la Schipol).
Having said that, irrespective of its possibility in fact, it is irrelevant.
The trail still needs unwinding to the moment of loss of control.

Reason: clarify, add derotate
