Nice video, thanks for sharing it, hadn't seen it before.

The most interesting things for me, apart from the sound of the engine in general, were the difference in sound when the cockpit window was closed, the variable sounds of the wind resistance when doing aerobatics, and the confirmation that I couldn't hear the other planes when he was flying in formation.

Edit - Nice flyby video too Gelbevierzehn's, posted while I was writing, thanks.
