Just watched the DVD of this years Warbirds Over Wanaka.
It's excellent! There is a lot of air-to-air footage. A lot of the air-to-air stuff was shot from a helicoptor, and includes much of the actual display flying. You get shots from above of the planes taxiing, then they take off toward the hovering chopper and either break to go around it or fly underneath it.
There is some cockpit footage of Ray Hanna getting a bump as he flys through the chopper's downwash
The commentary is fairly minimal, just the way I like it.
I hope the book is as good.
Cheers,
Brett
