Thanks for the pointer, Mike, certainly will get this.
I'm sad to have missed this one, sounds like a very special airshow indeed.
Down the rabbit hole: I dug out a BD-RE (!) disk I made in April 2004, and found a machine which attaches to a USB port to make it work

Was a great day, charter Convair 550 out of Auckland to Wanaka via CHCH and what a setting.
Next year for sure.
