I can remember during my last year at Junior school in the 60's the local cinema had the latest film on release 633 Squadron. It was a bit unfortunate as the timing of the release coincided with conker season and having used up our conkers in the traditional way, we thought of a way using up the bits! Ammo! Our imagination had been fuelled by the film, it only seemed natural to reinact it in the playground. We split into two sides each side occupying either cycle shed and carried out running battles for days.
If Health and Safety had been around in those days they would have been off work with R.S.I.
