It is and with modern antennas and bandwidth and auto-sharing between VDL and SATCOM it would be easily done (see for example
INMARSAT Iris ). Future aircraft can be expected in any case to have 'always on' broadband IP communications for other operational reasons, adding continual background recording would not be an issue. The days of hugely expensive 1200Bd intermittent SATCOM are well over bandwidths today are huge and continually increasing. However, there are those that do not want the recorder information, particularly the CVR information, 'shared' due to distrust in their operator's management. Yes in a completely unstabilized state
after a loss of control some connection could be lost but the lead up to the LOC would all be there. Within a few hours the recorder information of initial lead up to an incident could be in investigator's hands. For example all of AF447 information could have been available at the time of the crash instead of a 2 year wait.
