"Well, well, well........ any prizes for guessing why, with the black box recovered, ATC interrogated and the pilot alive; it may takes "years to determine the cause of the crash" ? !!!"
You may recall the Spanair crash at Madrid - almost exactly two years ago. The judge will provide a report in November - if we're lucky. My guess is more like next August - that's three years. So 'years' is what it takes in Europe, too. I agree - don't knock China for the transparency of their reporting.
