If and when they finally find the black boxes from MH370 the CVR will only have the last 2hrs of conversation or cockpit noises on it, so we will probably never know what was said when the course change was programmed into the computer. If I can buy a cctv set up at Costco for $250 that records 4 cameras for 30 days why cant a CVR last longer then 2 hrs? And a second thought, rather then storing the data in the black boxes why cant the ACARS or satellite up load the data either live or at pre-programmed intervals, say every 15 min. to a central storage location. So in a case like this there wouldn't be searching for the black boxes blindly, the CDR would give the last reported position of the plane and we would have already heard the CVR by then next morning? should be that hard or expensive to make a system like this?
