I agree with you all, well done on Prince William or any other Armed Forces employee who manages to lighten their mood using a helicopter without harming anyone else.
IMHO it's every boy's dream landing your helicopter in your Girlfriends garden or going to a party.
I always loved landing in my mum's garden.
In any case if you clamp down on these things I have noone telling me fantastic war stories of what they did during training.
