I've been off since Sunday night and haven't been around other pilots to discuss this.

Not inconceivable that a phone's SD card could have survived in 1 piece, or even be recoverable if damaged.
Other than your voyeuristic interest, what value would such a video provide? If any such videos (or messages) are found, you can be certain they will be played on an infinite loop on the 24-hour cable news shows.

(I wonder if this is another case where overexcited editors and reporters - anxious to get out their scoop - have reported incorrect information as facts?)
The CVR used to be an analog audio recording and, you're right, it was on a 30-minute loop (just continually writing over itself). The CVR is now a digital device and since 2008 the FAA has required at least two hours of audio recording (both ATC and ambient cockpit audio). The FDR is also a digital device and I'm sure it records at least the last hours of data, but I can't seem to find a reference for that.

You can't really expect me to give specifics on this in a public forum

It probably wasn't on autopilot, but there's no reason it couldn't have been. The autopilot will gladly accept a large descent rate (the pilot sets a Vertical Speed in feet per minute).

Thx
Very, very far. We do have remotely piloted planes (drones) and UAVs, used by the military, but that's a far cry from self-flying.
