AVIATION PING!................
How conveeeeeeeeeenient.
It automatically overwrites periodically.
I doubt there was nothing on it. More likely it operated for more than 2 hours past the event, so the earlier event was over-written. Per US policy.
AI ? LOL
I wonder if you can even give away seats on Alaska Airlines now. Someone needs to go to jail!
Easy to do I would imagine. A plane is not like a car where you turn off the ignition and everything powers down. I’m not trying to contrive any excuses, but if it works as I suspect it does, if no one shut off the CVR after they got on the ground as if they were parking the plan in a hangar, then the recorder was still running
One thing will come of this:
All maintenance personnel will be required to get covid booster shots.
Our entire government is completely full of lying malicious incompetents.
Top to bottom and side to side.

Correct, it runs on a 2 hour loop. If not turned off, it keeps running.
Interesting in Europe they run on 25 hour loops. Wonder why?
Because the Airline companies and Pilots did not want it running move than 2 hours so that there would be no record of “embarrassing” recording. In the age of digital recordings and hardware, seems to me 2 hours dates back to a time of TEAC recorders! Equally ironic, when we used body in my job in the 70s, we had recorders that ran for almost 4 hours, AIDS.
Which is why, if it looks like a review will be required, the crew can pull a circuit breaker to cut power, stop the overwriting, and preserve the record...?
And get DEI training.
In the old days, the CVR would record to a point and then start over; as I understood it.
I assume today’s systems are digital, but I don’t know if they erase, then begin recording again or what.
And this circumstance certainly warranted pulling the circuit breaker, didn’t it...
Informative answer at this link from a few years back...
[Correct, it runs on a 2 hour loop. If not turned off, it keeps running.]
I was thinking it was 2 hours as well. So that sounds correct.(?)
They are solid state IIRC, and after 2 hours are restarted at the beginning..............
Does EVERY plane have a handy switch to disable the federally mandated flight recorder?
I would be so lucky with my automobile!
The warning light went off three times and they just pushed the “acknowledge” button.
“Yeah, just a false alarm...let’s ignore it. Need to get that sensor adjusted sometime. The next crew can worry about it.”
That same thought process doomed the first Max that crashed.
