For those who haven't read my report, I'll make it easy.
https://ibb.co/d7dk26 is page four of the CAB report, saying the plane slid tail first and upright until it stopped.
https://ibb.co/kvz8N6 is a press photo of the main wreckage, showing the plane is upside down. If it's not immediately obvious to you, note the position of the main gear. It retracts forward from the main spar, and the brake lines which are behind the wheels end up below the main strut when retracted. You're looking at the bottom of the wing, and the leading edge is to the left.
There it is, real simple. Either the plane is NOT upside down, or the CAB is wrong. Take your choice.
Once you accept that the CAB is wrong, the questions are: How did the plane get there? What else did the CAB get wrong? How much of the official reports do we have to discard before what's left makes sense?
