Having lived on the IOW myself for many years, I too have seen such 'play' over at Alum Bay. Seems incredulous that they still get away with it, specially with the proximity of the regionals at Southampton and Bournemouth.
Virtually every visit I made there in about 30 yrs I would see some idiot flying about playing silly buggers.
One day someone will come to grief, and they will probably take some poor sod in a boat out too.
Like some car drivers, I get the feeling sometimes that the cereal companies are putting free driving/flying licences in their packets.
