Unfortunately, at the average drunken party on the Thames at Richmond, full of 'hooray Henry's' with a great deal more money than sense - it will be a great laugh to fly Marmaduke's new £5000 toy see if they can see into people's back gardens - then see how fast it can go or how high it can go..... what's an extended centre line? We are MILES from Heathrow...
And they wouldn't know an Air Navigation Order if it bit their backsides.
Unfortunately, whether we like it or not someone in an aircraft is going to hit one of these; and I don't think the regulators in Europe or the USA have a handle on how to deal with the problem.
