FDR and CVR
I've searched this thread before posting and have not seen the following issue with the CVR and FDR addressed.
Is there a "crush depth" for both of these recorders? It is likely, but not certain, that the CVR and FDR are both lying on the ocean floor perhaps at a very great depth. Do the recorders have specifications as to a crush depth? And even if they were both "crushed" do to ocean depth pressure would that preclude being able to read the contents thereof?
