Martin, there is apparently " no ceiling" on the next launch approval, meaning it is likely to go higher than the last one. The LabPadre Utube channel made a big deal of this today. As the ship cannot reach orbit in it's present configuration (3 x Raptors) and no booster, it is probably going to be limited to preserving fuel reserves on board sufficient to land; and they need atmo density for the wings to create drag on descent. There has also been some conjecture that they may use gas pressurisation (maybe from the RCS thruster tanks) into the header tank to ensure the LOX flows properly during the landing flip (as loss of LOX pressure caused the SN8 loss of thrust and RUD).
