Who (or what) to believe?
Tas62 asks who (or what) to believe?
Well . . let's look at some possible facts. Inmarsat basic data indicates that the aircraft was still viable (flying or landed safely) for several hours after loss of ATC and ACARS comms, based on hourly logon request/renew data (engines turning/ FMS operative).
Inmarsat then went on to do an innovative analysis of doppler shifts on the received data which gave some possible routes which appeared to preclude a landing.
Inmarsat have been slow to release the full data, possibly because as a telecommunications operator they may not release full logs as that would reveal other customer activity. Thus we can expect " edited" logs when they do appear.
There may well be conspiracies at work here but to date there is no firm evidence to support that view. Let's wait and see just what comes out. None of the parties involved (other than the designated SAR authority) has any clear reason or mandate to keep the guessing public-at-large informed.
