DoYouFly,
Here is an X-Plane version o the crash. X-Plane simulates physics, true flight dynamics and flight characteristics. See what you think, compared to the cartoon CNN has been using.
It is just as cartoonish as CNN's version. It bears absolutely no resemblance to any of the facts we know, or to the real-life video. To name just a few points: It comes in at a low pitch angle, it does not raise a wing as high as is clearly seen, it rotates the wrong way, ...

Yes, X-Plane can be a useful tool for making such visualisations, I have done this professionally before, but only if you use DFDR data for position, speed and attitude, none of which are yet publicly available.

Relying on X-plane's physics engine can only yield something useful if you know exact control inputs (rather: control surface deflections in any FBW aircraft) and the model has been validated to reflect the actual aircraft performance, even in these extreme attitudes. Hint: not even commercial full-motion simulators can do this, as no aircraft is aerodynamically tested in a cartwheel motion, except perhaps aerobatics types).

Nice to look at (or not) but bears no relation to actual events.
