'Sunny' I have seen a couple of YouTube Vids on Queenytown (great to observe) & as I mentioned have actually flown into there a couple of times but not in the 'Bus' on that App.
Sure it's a higher risk App than most but the plane doesn't know that it's just the drivers behind the steering wheels:-)
As I have mentioned b4 it's more about A/C perf than anything else where the risk is.
Anyway with 2day's modern tech stuff this shouldn't be rocket science at all, it's more risk assessment stuff.
