Malaysia Airlines 777 missing

Imagine streaming 88 channels of aircraft parameter, 3 or more audio channels multiplied by the amount of airliners flying, it must be huge...

Maybe it could be limited to times like these when something abnormal happens and the black box does a data dump.
 
I would also venture a guess that reliability would be a concern as well. Networks drop data packets all of the time for a variety of reasons. The communication protocols just retransmit any lost packets normally. In the case of an accident, the investigators want the data leading up to the last possible millisecond. Potential data loss isn't really an acceptable outcome in a catastrophic accident.

You could certainly use both methods to complement each other, but then you get into the cost/benefit and likelihood/severity risk issues.

What's been spotted
 
This has been a hot topic at AF after the AF447 where it turned out a live stream could have facilitated the location of the wreckage, and also incorporate more than just a homing beacon on the FDR, the idea would be to broadcast it's last known position along with the beacon...
 
I wonder if anyone has looked at what ships might have been in the region at the time, and requested a copy of their radar tapes? There was bound to be commercial shipping, and possibly military vessels as well, in that area (are there ever NOT, that is a high traffic region!?). Most of them keep the tapes for at least a while for liability purposes.
 
The news that both of the stolen passports where purchased together adds to that theory even more. I was thinking about that last night. What are the odds that 2 stolen passports where used to board this flights. Bother were taken from Thailand roughly around the same time from two separate locations and now to find out both tickets were purchases together. I hate to say it, but that looks like more than just a coincidence in my opinion.

That doesn't bother me too much. There is a vibrant trade in passports. Sell you passport to a street broker, pocket some spending money, stop by the consulate and replace it.

Anyone have a good reason why flight data is still stored in the black boxes and not relayed and stored on the ground?

The same reason a lot of good and bad ideas are not implemented on aircraft: the cost of making changes and type certification.

The bandwidth required to stream the same data going to a modern FDR is minuscule, 16 kbps (roughly 9.6 kbps if you do any kind of run-length encoding, puff that up some if you also want it encrypted)..
