I agree. In reflection, we either already know what happened or have enough data to make a reasonable assumption and start to take corrective action. Including but not limited to:
- Better dissemination of weather information
- Better training, SOP clarification and use of WX radar
- Be more proactive/aggressive in diverting around bad weather
- (my favorite: hand fly the AC through the ITCZ vs using the autopilot, so if you run into unseen weather, the crew isnt tossed an unstable aircraft into their laps when the AP runs for the hills )
- More active collaboration between 'hand off zones' (like Dakar)
- Faster response when the plane goes missing
All these things we know now, what else is the CVR FDR going to tell us? Useful? perhaps, but not particularly earthshattering - though I guess hearing and seeing their final moments trying to correct the plane may offer some training suggestions
