Air France 447 search for black boxes

It’s always sad to hear about an air disaster. One way to advance air safety is to review data recovered from the onboard flight and voice recorders. Unfortunately in this crash these devices may never be recovered. I was wondering if anyone has considered uploading a stream of data of each flight to a terrestrial server? Storage and bandwidth are cheap these days and current speeds should be sufficient to move significant data.  The idea would be to get a recording of each flight for analysis.  The data could even be analyzed for fuel efficiency and predicting component failure. My model is some of the more sophisticated servers that keep data of disk errors, temperature spikes and CPU utilization. When something goes or failure seems imminent they issue an alert that is sent to a monitoring program.

Perhaps each flight can be “recorded”. If an event or accident occurs the “tapes” can be reviewed. Just my idea.
