Bearfoil, you are reaching way too far. You are presuming the airline is so cheap they'd send messages via HF rather than SatCom when the plane is SatCom equipped. And I am not at all sure HF would be even pennies a message cheaper. It would certainly be less reliable without some serious Automatic Link Establishment sort of technology. HF propagation is not necessarily a hands off operation without such technology.
You have a habit if making unsupported and too often unsupportable assertions. And you are back to your mantra that you said you never discuss, "the VS er Fin came off the plane and caused the accident." This gets REALLY tiresome, sir.
I'd also like to note that there was a previous trouble message included in the logs - one of the potties had a problem.
