I was lucky enough to go to Wanaka this year,it was absolutley fantastic! I can't think of a better venue for an airshow anywhere in the world. They had some interesting formations like:
2 P-51s, 2 P-40 Kittyhawks and 2 Vampires all in formation then doing a tail chase.
The Hunter and Sea Fury and Hurricane did a goog routine,
The Hurricane and Spitfire flown by Keith Skilling and Ray Hanna respectively also did a superb pairs formation sequence.
The Polikarpov's were also really good as was the mock airfield attack by the Harvards. There was also some RNZAF types suchas C-130, P-3 and 727, red checkers and RNZN Sea Sprite.
Piece of cake
