Hoping to satisfy the Holy Trinity by stating both rotary and fixed qualifications, and having 'pushed the boundaries' more than a few times - cutting through the crap here:--
Surely the lesson is that if you are going for a bit of skoshie as Mr Hanna used to call it, don't do it
a) Below the level of nearby obstructions
b) Over built-up areas, so far less chance of taking an unfortunate bystander with you?
This does not just apply to rotary!
