Peekay4, Thanks for a damn great answer, but your damn great answer leads to more questions. This first one you may not be able to answer.
Why was the aircraft allowed to turn around and take off for it's next leg after an incident allowing the CVR to be over written (If that is the case)? In South Africa. you will be ordered to vacate the runway if you are on one, stop and shut down immediately.
Where is the CVR delete button? Is it easily accessible in the cockpit?
