The chances to UNDERSTAND everything with readable FDR and CVR are near 100%.
Remember you are continuously recording before and after the "air speedometer"
fails. This fact,the number of parameters you can analyze, their timing together with AUDIO recorded in cockpit from many sources (microphones) allows a very complete analysis. Fascinating, indeed.
Very probably we will be able to Xcheck with ACARS because electrical supply to the recorders may be lost only at sea surface impact.
