Two schoolgirls have become the world's youngest formation wing-walkers.

Rose Powell and Flame Brewer, both 9, took to the skies over Gloucestershire on Wednesday.

Encouraged by their grandfather, who is a professional pilot, they undertook the record attempt to help raise awareness of Duchenne Muscular Dystrophy.
