The Shield Xyla is a one off design by Gorge Shield, who was headmaster of Mexborough Grammar School in Yorkshire. It was built at the school, which shows a level of trust in the pupils which would be hard to find these days! It first flew in October 1971. Powered by a 65hp Continental engine, it cruises at 110mph and has a range of 500 miles.
And Xylitol is a sugar from birch tree, used to fight caries.
