It seems to be the major repository of both crackedpottery and some good analysis. Let those with "ideas" for solutions mine that thread to see if they've presented anything new. For example, satellite FDR/CVR is very much "not a new idea." So far a cockpit video recorder linked to base by a satellite connection has not been proposed. So it's not THAT far "out there."
