Angus Houston's mention of 2 apparent (but 'distinct') ULB signals (presumably CVR + DFDR) is significant.
Amid much of the 'scenario' speculation (!) on this thread, if the aircraft did end up relatively intact on the sea-bed & still containing the boxes, how might they be retrieved?
[1] Can any of the deep-submersible AUV/ROVs perform any kind of hull cutting activity?
[2] Can hoisting gear be remotely attached to any fuselage structure?
