already. However, stop for a minute and consider the 10s of thousands of
aircraft airborne at any given moment in time. You are talking about a
*lot* of data. Data that no one cares about, except in extremely rare
circumstances.
1) To an approximation, the A/C was transmitting data to the home base.
That's the primary basis of what the guesses about what happened are about.
2) Since customers enjoy (and are willing to pay for) telephone and
internet services while in flight, there is the potential of having plenty
of bandwidth available to "maintenance." Data storage is cheap and
getting cheaper so at least a "data summary" can be kept 'just in case.'
There is a "privacy" question as to whether cockpit voice should be
automatically "phoned home."
3) It's clear from this accident that the whole issue of the "black
boxes" should be re-visited. First, how should the data recorder be
protected/packaged/and "beeped." What should be monitored? Should
the data be "processed" before being stored? When consumers routinely
store an hour of video on an inexpensive 'chip', the 'technology' of the
black boxes looks that something from a century ago.

If this has been addressed before I apologize. With all the
sophisticated electronics on a plane, can't the black box data just be
transmitted as it's occurring to a central processing station?
Wouldn't this be a viable solution to investigate crashes, and allow
new safety measures to be put in place faster? Why can't something
like this be implemented? Isn't the data digital? If not, could it be?
It would seem an easier, faster, more efficient method than all the
time and manpower and expense needed to find these black boxes.
As electronics advances this could very soon be possible, if it's notsophisticated electronics on a plane, can't the black box data just be
transmitted as it's occurring to a central processing station?
