The aerodynamics of that maneuver confuse me (but I got a B- in dynamics back in college). I mean, if the chopper blades are no longer providing lift but are pointed downward, shouldn't that be bad? I guess they must act as a wing in some way as well...

^^That's why it boggled my mind as well. I figured that it would begin plummeting but it was actually able to hold position and even rise further while upside down.

I think I heard earlier in the week on NBC news that the pilot is the only one in the US that is licensed to perform these kinds of stunts in a chopper, but who knows if that's true or just an advertising ploy.
