Realistic Flip Animation

I have read tutorials and scoured the internet in search of how to make realistic animations just like the flip animation here: http://www.matthewmahon.com/
(just click and image to zoom on, then click the arrow at the bottom corner)

I am currently working on a project that requires a similar animation, but it needs to look just as realistic. If anyone has any information as to how to achieve this effect in flash.
