(WUSA9) -- Nine-year-old cousins Rose Brewer and Flame Brewer are the world's youngest wingwalkers.
The Brewer cousings wingwalked over Rendcomb airfield in Gloucestershire, to become the world's youngest formation wingwalkers on August 21, 2013 in Cirencester, England.
The two girls who flew on vintage Boeing Stearman biplanes, were inspired to do so by the plight of Eli Crossley who suffers from Duchenne Muscular Dystrophy.
The pilot's parents have set up the Duchenne Children's Trust to raise money to research a treatment or cure in time to save Eli's life.
