(I am not a heli pilot); Just for my interest; how does one navigate in such confined spaces, near trees etc?
It is obviously vital not to stray towards the obstacles, so how do you ensure that? Do you fix on a feature on the ground underneath the heli and keep it directly below you, (but obviously where you can see it)? Tricky to do on grass, I would think.
Secondly, this heli is operating in what looks like a car park with members of joe public walking past very close by, and with no marshalling; is that sensible? And was it sensible to use that particular car park - surrounded by tall trees - in the first place?
