Intriguing. I have put the broken part back in position, but they still make little sense.
Thanks for doing reconstruction image of tail fin. I had something like that in my mind.
these vertical scratches were not present before crash. And they must have happened in flight.
They are located right over HS trailing edge. Could be marks from departing HS. Note how parallel these scratches look! Same event?
It could mean that forces that made HS to fail were from below, relative to fuselage of course.
