While 9000fpm is fast its not THAT fast (its less than 100knots), and doesn't seem to be consistent with the speed of impact implied by the photos of the crash site. Since the crash site photo is "real" and the 9000fpm is a report and subject to being wrong for various reasons, based on the VERY limited info we have now i might be tempted to suggest they came down a LOT faster than that...
I Agree
Looks to be closer to Mach 1 and 70 to 80 degrees ND.
Not pleasant to contemplate.
