quote "Did all Tx (ACARS) arrivee via FIN?? Or was the last one, the Cabin Speed, tx by the Fuselage, after the famous gap in ACARS, the loss of the Fin causing the Bus to switch to SATCOM?? If so, that explains the gap in tx, and would explain the possible loss of the Fin at altitude, coinciding with a depressurization, a hull rupture, and the possible loss of some cabin contents, explaining the lack of damage to the Galley structure, when the recovered cabin liner right next to it was utterly destroyed."
That's the sequence that has been bugging me since the beginning. That galley floating relatively undamaged seemed to tell a tale of a back-broken airplane spitting parts. BTW what exactly does UAS mean?
