SATCOM and Telemetry Data?
Concerning Data:
Why has nobody confirmed/announced if there were any transmissions sent via SATCOM? Seems to be the elephant in the room - the media currently appears to have an unhealthy tunneled obsession with; radar, ads-b, voice comms, gps, black boxes, etc.
Surely ACARS and engine telemetry data could shine a good dose of light on this incredibly sad fiasco.
Many aircraft today also have Panasonic Avionics high-bandwidth eXconnect GCS (Global Communications Suite) to augment SATCOM.
