One day the CVR industry will come up with an ever so simple way to avoid this overwriting. Goodness knows how often it has occurred in incidents in the past. I know the requirement is to maintain the last 2 hours, but that didn't extend to any instruction to start overwriting at 2 hours and 1 minute.
I'm sure NTSB will lament the absence of CVR for this incident/accident, but where it's really hurting is the near miss/runway incursions where ... somehow ... 😯🫢🤫the recording always goes missing. You can be sure that at least some of the flight crews involved in these incidents are pleased as punch that CVR audio "just happened" to get overwritten.
That's what really needs to stop.
Aircrew in the US are fortunate to work in a system where human error is almost never a criminal matter, but the flip side of that is that safety culture requires honest participation in fact finding, and of late, it hasn't been happening.
