Yes, when North Korea hacks them.
(seriously, our NTSB has some pretty amazing protections at CVR and FDR data, I'm guessing that's not really going to happen here
)
I was reading the story this morning and thinking to myself: yeah right, I bet they'll be leaked/revealed/hacked.

I've been receiving some PMs that discretely suggest there may be some parallels (previous accidents) that some parties may have a vested interest in not discussing publicly. I'm starting to doubt that the CVR will have much weight in determining the real cause here anyhow. FDR data likely far more important. It's release would just baffle the average newspaper subscriber. The complexity and sample rates of the data would even baffle many pilots. It's interpretation however subject to speculation of the investigators.
My speculation? The tail came off this airframe in flight.

That doesn't explain the high rate of climb prior to the rapid descent.
The tail did come off---it was found quite a distance from the majority of the fuselage.
But inflight breakups where the tail comes off (at high speed) usually result in a negative-g pitchover, departure of engines, and the fuselage failing near the wings.
I think it came off at lower speed.....possible a spin/departure that the protections in the Bus couldn't have prevented (super updraft).

Are we talking tail-end completely blown off, or more of a JAL123 type of situation? That flight flew for quite some time giving ample time to radio in a distress call.

JAL 123 Had a stub of tail remaining. It flew for almost an hour.
AA 587 sheared the entire fin off; breaking the steel attach flanges (and not the composite surface, as detractors speculated). It went into a spin almost immediately; centrifugal force tore the engines off within seconds.
8501's tail (during recovery operations) clearly showed it was attached to a significant portion of rear fuselage.

Don't know what happened but it does sound like they are looking at a failure of both FACs.

I'm guessing you haven't seen the pictures of the tail section yet. It was still very firmly attached to a portion of the aft fuselage.
If it did come off, it took part of the fuselage with it (not a shearing event like you seem to be speculating).

Question for Airbus 320 series drivers: Could TS updraft/downdraft encounter result in regressed and/or alternate law flight mode(s) and make FAC failure more likely? I assume FAC failure means loss of yaw damper also.
Thanks.
