ICAO must ban the Black Box as the unique place where to store Flight Data for all Commercial Flight. We have better ways to capture airplane crash data.
The All Data live-streaming, via Satellites, to be stored into Air Lines Servers, is the best solution for SAR (Search and Rescue) Operations; especially for crash into far locations or deep sea.
Also: Why not mount an adequate number of HD CCTV cameras on airliners to monitor the status of wings, rudder and other critical parts of the aircraft in flight? and of course all data must be safely recorded into ICAO Cloud.
