This reminds me of the demo 'bus crash when the senior pilot got real low and the flight controls limited his pull-up and the motors didn't spool up real quickly and.......
There's a time to show off the capabilities of the jet and such, but not with 40 SLF's along and in marginal weather while in mountainous terrain. Sheesh.
The CVR will show more than the FDR, IMHO. We may learn what the decision process was, and the impact point and flight path will only show the raw stats.
My buddy flew into a mountain near Cali about 16 years ago after turning back from a flawed FMS setting concerning the radio beacons and waypoints. Unfortunately, the turn was too wide to reach the intended waypoint and they kept descending with terrain ahead. BAM!! I honestly believe he had a better chance of avoiding impact than these guys. Almost made it and it wasn't a vertical cliff. A few survivors, as well.
