You raise the same issue- reasons I stated in my post

but more terse and simple.
IF aft section torn off by explosion and pressure issues ahead of PB, then HS and VS would be a relatively complete unit and as it fell would generally align itself to minimum drag or if not would not develop enough " leverage" ( opposite force ) to rip off HS external to tail section- thus landing almost intact but for impact damage. But photos to date do not support this analysis.
I note that CVR and FDR were ' recovered ' and probably were part of tail cone aft of PB since that was the location- but NO- repeat NO photos of nearby jackcrew and internal HS ' wing" Box which is more massive than the nearby skin/stringer attachments/shelves holding the CVR-FDR.
Something is still missing from released info
