FDR & CVR – Why don’t they float, they don’t have to but it would be really useful if the memory modules did and what’s more, think 16GB USB stick, wouldn’t it be useful if the data was ported to more than one memory module and both voice and flight data were recorded on the same module.
Now the memory is so small it should be able to fit in just about anywhere, even wireless is possible.
One thought on the current situation. If the aircraft broke up and the rear section is partially intact, perhaps with the rear bulkhead still in place, it may actually be floating sub-surface due to trapped air and the recorders may not be immersed and therefore, not pinging but perhaps transmitting.
One item mentioned earlier – the press in emergency button, which would ACARS and transmit an automatic position report/heading/speed/altitude and keep doing it until cancelled is a brilliant idea, should be one on every joystick.
Can you imagine what would have happened if they had managed a successful ditching but not been able to talk to ATC or Paris first.
Lastly, I wouldn't rule out those other sounds, unfortunately fish and probably squid will be attracted to the wreck and whales of course eat squid so definitely listen for them.
