Teacher from local school (lives close by) has asked that I bring a helicopter in at the end of term to show the kids! Seems I could save myself time & money by quoting H&S at them.
Private school, though, so more concerned with showing kids what they can do if the work hard. That bit has gone out of fashion in State education. I think it's a good idea and I am going to do it.
