let me have a goat answering your objections, that are all well made.
(A) acknowledged but there may be solutions or partial solutions that do not rely on satellite. How is ACARS transmitted?
(B) probably not but it is almost always a necessary element.
(C) I agree bit it should be easy to establish whether or not streaming costs spread across the global fleet would be less than occasional recovery costs. Has the calculation been made? I don't know but it surely ought to be made.
(D) possibly true but if the DFDR/CVR is available, there is possibility of a partial answer rather than no answer.
