Do the fireworks come with these notices?
I'm just curious as the layman buying fireworks from Sainsburys (or one of the short-lived firework shops) is unlikely to be aware that he would have to inform the CAA, nor is he likely to know exactly how high the 'super-charger-whizz-bang' rocket he just bought is likely to go. Or in reality does the 250ft limit basically mean the big professional shows?
