Thanks for these clarifications.
As stated, several factors weigh heavily against satcom-based streaming - yet the idea gets brought up now and then. So let's say there are research interests in the way ICAO considers problems and possible solutions with somewhat complex cost-benefit assessments, or in developing new segments for international air law curricula, or in preparing background material to be used by one of the sector organizations or specialized government agencies.
Rather than taking any side on the merits this SLF/attorney is only looking at how digging into the record of ICAO's review of the issues might be pursued, below the easy superficial (official) record that's readily accessed. (Such is the dullness of legal and policy research....)
