It's also very cool to watch the smoke behind the airplane, as well as the smoke that's flown thru in various maneuvers. Pay attention to the rolling tailside that starts at about the 3:15 mark... once the airplane stops the vertical climb, Jason turns the smoke off and then keeps rolling as the airplane descends backwards. It's awesome watching him work the rudder pretty much from stop to stop to keep it falling straight backward - and it goes on for a really long time!
I also really like the hangin'-on-the-prop pass that starts at the 5:30 mark. It's interesting to see what visual clues he's using as he has the airplane nearly stopped, hanging on the prop. Here again I like watching the tail surfaces as they move... and you can see some high frequency vibration in the fabric on the stab, and the stab itself from all of the intense turbulent flow and vibrations.
